Field Nation ↔ Autotask integration specialist (20 hours, must have used Field Nation's Autotask connector middleware for integration before) We're an MSP running Autotask (PSA) and dispatching field technicians through Field Nation. Using Field Nation's prebuilt Autotask connector, I've already got it creating an Autotask ticket when a Field Nation work order is created, and updating that ticket when the work order changes. What I'm looking for is someone who's done this specific integration before and can take us the rest of the way. Two things I need help with: 1. Finishing the configuration — mapping all the data we want to see flow into Autotask (we're partway there), and getting the field mappings/defaults right. 2. Strategy — I don't want to just make our current process work and miss the bigger picture. I want someone who can look at what we have, understand our business goals, and advise on the best way for these two systems to work together (one-way vs. bidirectional, which fields, avoiding sync loops, what's worth automating vs. not). I plan to buy 20 hours to accomplish the following: a review of our current setup, a best-practices recommendation tied to our goals, hands-on help completing the mappings and direction design, and ideally a short written runbook so we can replicate it in production. To apply, please tell me: - Where you've configured Field Nation's prebuilt Autotask connector specifically (not just Autotask's API or a generic iPaaS tool) — which client/use case, and what you mapped. Screenshots or a reference are a plus. - How you handle setting static/default values on created tickets (e.g., AccountID, Queue, Status, Priority). - How you approach bidirectional sync without creating update loops. - Your availability and time zone. Process: I'd like a short intro call first to understand the work you've done and confirm fit. If I'm confident in your experience, we'll move forward with a block of hours. More hours may be approved depending on results.

SHOPIFY CUSTOM APP MIGRATION — LIFT-AND-SHIFT, NO DEVELOPMENT I'm looking for an experienced developer to perform a clean lift-and-shift migration of two existing custom Shopify apps from my current development agency's hosting infrastructure onto hosting that I own and control. This is purely a migration job. No new features, no code changes, no enhancements. The apps work as intended in their current state — I simply need them moved. THE TWO APPS BEING MIGRATED 1. A custom currency recorder app used for dual-currency (KYD / USD) transaction reconciliation in our Shopify store. 2. A custom Shopify POS UI extension that integrates with our in-store loyalty program (Jericommerce). Both apps are currently live and in operational use. They cannot go dark, even briefly, during the migration. WHAT I NEED FROM YOU - Coordinate with my current developers to obtain the source code, environment variables, deployment configurations, and any other materials needed to redeploy the apps on new infrastructure. - Recommend a target hosting environment that makes the most sense long-term for this kind of workload (e.g. Render, Heroku, AWS, DigitalOcean) and explain why. - Stand up the new hosting environment under accounts that I own. - Deploy the apps onto the new hosting in a staging state, run them in parallel with the existing deployment, and confirm they are functioning identically to the current production version. - Confirm with me, in writing, that the migrated apps are fully functional before any cutover takes place. I will not authorize the cutover until you have demonstrated the new deployment works as expected. - Execute the cutover — switching webhook endpoints, DNS, Shopify app URLs, or any other relevant routing — in a way that produces zero downtime or operational disruption. - Verify all Shopify connections (webhooks, OAuth, app proxies, POS UI extension registration, etc.) are correctly wired to the new hosting after cutover. - Document the new deployment so I have a clear record of where each app lives, how it is accessed, how the environment is configured, and how to maintain it going forward. WHAT I AM NOT LOOKING FOR - No new features. - No code refactoring. - No "improvements" to the apps. - No exploratory audit or rebuild. - The apps work. They just need to live somewhere else. If you see something in the codebase you'd genuinely recommend addressing, flag it to me separately — but do not change it as part of this engagement. Migration first, anything else later, only if I ask. WHO YOU'LL BE COORDINATING WITH This migration involves three parties: 1. You (the migration contractor). 2. My current development team (who will provide source code and deployment details). 3. Me (overseeing the engagement and approving the cutover). You will need to be comfortable coordinating with my current developers professionally to obtain what you need from them. The relationship is winding down, but the handover should be cordial and efficient. I will introduce you to them directly once we have an agreed scope and timeline. WHAT I'M LOOKING FOR IN A CONTRACTOR - Strong experience with Shopify custom apps (private apps, public apps, app extensions, POS UI extensions). - Strong experience with cloud hosting and deployment (Render, Heroku, AWS, DigitalOcean, or equivalent). - Experience with zero-downtime migrations and parallel-deployment cutover patterns. - Comfortable working with code you did not write and deploying it without making changes. - Direct, honest communication style. I do not need to be managed or shielded — I just need clear updates and reliable execution. - IP ownership: all deployment configuration, hosting accounts, environment variables, and documentation produced under this engagement belong to me. QUOTE AND PROPOSAL Please provide: - A fixed-price quote for the full migration as described above. - Your recommended hosting environment and rationale. - An estimated timeline from kickoff to cutover. - A brief description of your relevant prior experience (Shopify app migrations, hosting transitions, or similar). - Any clarifying questions you have before quoting. Looking forward to hearing from you.

Project Overview: I am seeking an expert Python developer to build a lightweight, local automation script that bridges custom TradingView indicator alerts to Interactive Brokers (IBKR) for automated options execution. Core Deliverables: Webhook Listener: A local Python script that securely listens for JSON payloads sent via TradingView webhooks. Dynamic Option Chain Scanner: Upon receiving a payload containing specific parameters (Ticker, Target Delta, DTE), the script must query the live IBKR option chain (using ib_insync or ib_async), find the exact or closest available strikes matching that Delta, and calculate secondary strikes based on distance to the current spot price. Complex Multi-Leg Order Routing: The script must dynamically assemble these strikes into a specific 5-leg complex combo order (combining a credit vertical spread, two debit vertical spreads, and a naked wing) and route it to the market as a single transaction using mid-price algorithmic fills. Rigorous Error Handling & Logging: The code must include strict safeguards (rate limits, bid/ask spread checks, and fallback logic if an exact strike or delta is unavailable) to ensure no rogue orders are fired. Developer Requirements: Demonstrated expertise with the Interactive Brokers API (ib_insync framework heavily preferred) and TWS/IB Gateway. Deep understanding of options mechanics, including how to handle complex multi-leg combinations and delta sourcing. Excellent, proactive communication. Weekly availability during standard New York market hours (EST) for live testing. Must be located in the United States (required for IP protection and NDA enforcement). Workflow & Milestones: Initial development and testing will be done exclusively using an IBKR Paper Trading account. The project will be managed via two strict milestones: 1) Full execution validation in a paper environment, and 2) Live market deployment verification using a single test contract. If you have read this entire post and have experience with IBKR options routing, please start your proposal with the word "DELTA" and briefly describe a past algorithmic trading project you have built.

Full-Stack Developer | Freelance, Project-Based About Our Requirement We are seeking an experienced full-stack developer to work with us in transforming an early-stage concept into a polished, market-ready web and mobile application. This is a long-term opportunity to play a key role in shaping and continually improving the product architecture, user experience, and technical implementation while collaborating closely with the founders. Our objective is to create a subscription-based educational technology platform that helps families and students to better organize and manage academic information through a simple, intuitive interface The ideal solution will securely integrate commonly used educational tools and systems into a student dedicated web and mobile app providing users with a streamlined experience that reduces complexity and improves day-to-day organization. The project has progressed beyond the concept stage, with core functionality, a preliminary dashboard and workflows already defined. We are now looking for a developer with the skills to refine the platform, build a scalable and secure architecture, integrate with appropriate third-party services and APIs, and prepare the product for commercial launch. The Opportunity Based on the parameters noted above, we are seeking a mid-level full-stack developer to work directly with the project owners (non-technical but closely involved in every design decision) to help us finalize or vision and providing †he expertise to scale up our platform by applying secure real data integrations, adding durable data storage, and improving reliability — while preserving and enhancing the ease of functionally and user accessibility. Project Scope (Phase 1) • Interact with the founders to develop the means to migrate dedicated data from multiple platforms into our unique web based/mobile App. • Assist the founders in the creation and deployment of hosting and custom domain configuration. • Design and build a lightweight backend + database layer (e.g. Vercel serverless functions with a hosted Postgres database, or similar) to replace localStorage-only persistence • Evaluate whether to keep the current vanilla HTML/CSS/JS front end or migrate to a lightweight framework (e.g. Next.js), and implement that recommendation • Maintain and extend the accessibility standards already established (WCAG contrast, dyslexia-friendly typography, reduced-motion support) — nothing developed should regress readability for a dyslexic user • Set up a system of basic monitoring/error logging so issues surface before the subscribers are negatively (in terms or platform use) affected. • Document the codebase and deployment process clearly enough for a non-technical owner to follow Required Skills & Experience • 3+ years of professional full-stack development experience • Strong JavaScript/TypeScript, both front-end and back-end (Node.js) • Experience building and securing REST APIs, including OAuth 2.0 integrations with third-party services • Experience with serverless deployment (Vercel, Netlify, AWS Lambda, or similar) • Comfortable designing a database schema and working with a hosted database (Postgres, MySQL, or similar managed service) • Solid understanding of Git/GitHub workflows • Working knowledge of web accessibility standards (WCAG 2.1 AA or better) • Able to work independently against a scoped project brief with minimal day-to-day oversight • Experience integrating with EdTech platforms • Experience designing for neurodivergent users (dyslexia, ADHD, or similar) or prior accessibility-focused UX work • Familiarity with Next.js or similar lightweight React frameworks • Comfortable explaining technical tradeoffs to non-technical stakeholders Working Style This project is owned by a student’s parent, not a technical team — clear, patient, jargon-free communication matters as much as the code. You should be comfortable: • Proposing options in plain language and guiding the founders to understanding critical issues in order to (as a team) make informed decisions • Working within an existing, already-designed visual system rather than starting from scratch • Delivering in small, reviewable increments rather than one large handoff at the end Engagement Details Type: Freelance, project-based (fixed scope with a defined set of ending objectives) and a long-term potential for follow-on work) Location: Remote Estimated timeline: [Phase 1 – target implementation date – August 31/2026] [Phase 2 – to include platform refinements based of in-use feedback and scaling the platform up to allow for beta testing of 10-20 users] Budget: [Phase 1 - $ 2,000.00] [Phase 2 - $ 1,500.00] Start date: [Immediately] How to Apply Please provide relevant past projects (especially any EdTech, accessibility, or OAuth/API integration work), your estimated timeline and desired rate (fixed or hourly) for the scope above, and any questions or alternative approaches you'd suggest for the backend/data layer. Please Note: A signed Non-Disclosure Agreement (NDA) is required before the start of this project engagement. This ensures that all confidential information shared throughout the project remains protected and that both parties have a clear understanding of their confidentiality obligations.

**Project Overview:** I am looking for an expert developer to build a lightweight desktop stock ticker application (Windows/macOS preferred) where the MAIN focus is high-utility, fully customizable AUDIBLE alerts. I want to monitor the markets by ear without constantly staring at my screen. The app will feature a customizable "Quote Builder" layout running on fast user-defined refresh loops, but the sound engine is the absolute priority of this project. **Core Audio Requirements (The Main Point):** * Event-Driven Sound Profiles: I need to assign distinct, custom text-to-speech (TTS) speeds, pitches, or triggers based on user-defined price movements. * Directional Audio Logic: Distinctly different tone pitches or speech profiles for "Up" ticks versus "Down" ticks so I can instantly hear market direction. * Speech Profiles: A drop-down menu to toggle between "Standard Mode" (reads full labels: "Tesla 100, up 2, bid 99...") and "Pro Mode" (strips all labels for high-speed tracking: "TSLA, 100, up 2, 99..."). * Global Panic Mute: Hitting the Spacebar or a dedicated hotkey must instantly mute/unmute all active audio feedback immediately. * API Key Settings & Data Feeds: The app must use a "Bring Your Own Data Feed" architecture. It must feature a configuration settings screen where users input their personal, API credentials (keys and tokens) to feed data into the ticker. * Brokerage Dropdown Selector: The UI must include a simple drop-down menu allowing users to choose which data provider or brokerage connection to activate (e.g., [Dropdown: Alpaca Markets, Polygon.io, Interactive Brokers, Yahoo Finance]). The developer must build modular data adapters for these connections. **Data & Interface Requirements:** * Custom Quote Builder: Ability to save layout templates choosing from fields like Symbol, Last Price, Up/Down, Bid/Ask Size, Day High/Low, Open, and Close. * Fast Polling Loops: Drop-down selector for data intervals per ticker: 1 second, 5 seconds, 30 seconds, 1 minute, or 5 minutes. * Multi-Monitor Support: Global hotkeys to switch saved templates instantly without needing the app window to be in active focus. * Ticker Looping: Supports inputting a single ticker or a comma-separated list to cycle through multiple stocks on the interval loop. **Budget & Contract Setup:** * Contract Type: Fixed-Price * Total Project Budget: $3,000 (To be broken into milestones upon signing an NDA) ⚠️ CRITICAL: You must start the very first word of your cover letter/proposal with the word "TICKER" to prove you are a human and not an automated bot. If your proposal does not start with the word "TICKER", it will be instantly declined without review. Please reply by explaining your experience with asynchronous programming, audio-based desktop systems, or handling high-speed financial APIs (like Alpaca or Polygon.io). Selected candidates will be asked to sign an NDA before receiving the full requirements document.

I’m building Elevyn, a platform designed to help people better understand themselves through connected data, intentional reflection, and AI-generated insights. This is not a social media platform. This is not a productivity app. This is not just another trading journal. Elevyn is an operating system for self-mastery, with trading serving as the first environment where personal growth becomes measurable. Most apps collect data. Elevyn is designed to observe. The goal is to connect information across different areas of a person’s life and uncover meaningful patterns that help them improve their decision-making, habits, discipline, and overall performance. The Vision Users will log information such as: • Sleep • Mood • Daily reflections • Workouts • Morning routines • Trading activity • Goals • Habits • Personal notes Instead of simply displaying this data, Elevyn will analyze relationships between it and surface meaningful insights. Examples include: • “You slept less than 5 hours before 7 of your last 10 losing trades.” • “Your win rate increases after completing your morning routine.” • “You tend to become more impulsive after multiple winning days.” • “Your consistency improves when workouts and journaling happen on the same day.” The long-term vision is an intelligent system that continuously helps users become more self-aware. Current Stage I already have: • Brand identity • Vision and philosophy • User flows • Interactive prototype • Core feature planning • Long-term roadmap I’m now looking for a developer or small team (2-3 people) to build the first production version. What I’m Looking For I’m looking for someone who can think beyond simply building screens. I want someone who can: • Build scalable architecture • Recommend the best technologies • Think through user experience • Ask thoughtful questions • Help solve technical challenges • Build for future AI integrations • Create clean, maintainable code Experience with AI, analytics, mobile applications, and scalable backend systems is a significant advantage. Technology (Open to Recommendations) I’m open to your recommendations, but I’m considering: • Flutter or React Native • Node.js or Python backend • PostgreSQL • Firebase/Supabase • AWS • AI integrations (OpenAI or similar) • Secure authentication and cloud infrastructure Long-Term Vision Trading is only the beginning. The underlying engine should eventually support entrepreneurs, athletes, creators, students, and anyone pursuing mastery in a specific area of life. The core idea remains the same: Help people understand themselves by connecting patterns across their behaviors, decisions, and outcomes. Who I’m Looking For I’m looking for someone who believes in building meaningful products—not just completing tasks. If you’re excited about creating a platform that combines psychology, data, AI, and personal development into something people genuinely use to improve their lives, I’d love to hear from you. Please include examples of similar work, your recommended tech stack, and how you would approach building a scalable MVP that can grow over time.

*NO AGENCIES, Single Engineers Only* SeatWaves is a live ticket resale platform with a fully operational web version, complete Broker API, and TicketMaster API integration already in production. We are looking for a skilled mobile developer to finish the final leg of our iOS and Android app — not start from scratch. The previous development team completed approximately 88% of the mobile frontend UI. The Figma designs are finalized. The backend APIs are live. What we need now is someone to come in, understand the existing codebase quickly, wire everything together, and deliver a production-ready app. What's Already Done → Live web platform (full-featured, production-ready) → Broker API — fully built and operational → TicketMaster API — fully integrated → Figma UI/UX designs for iOS and Android — finalized and approved → iOS & Android frontend — ~88% complete (UI built, needs backend wiring) What Needs to Be Completed → Wire existing mobile frontend to live backend APIs (authentication, listings, checkout flows, broker inventory) → Integrate TicketNetwork API — inventory feed and seat availability → Implement interactive seat map API integration → Bot protection and rate limiting hardened for high-traffic onsale events → Queue integrity and load-resilience architecture for peak traffic → End-to-end QA testing on iOS and Android → Store-ready builds (App Store + Google Play submission prep) Why $1,500? We want to be transparent about the budget and why we feel it's fair for the right developer. The heavy lifting has already been done. The UI is built. The APIs exist. The designs are approved. This engagement is scoped specifically around integration, security hardening, and QA — not ground-up development. We estimate 3–5 weeks of focused work for an experienced React Native or Flutter developer who can hit the ground running. We are not paying for a full build — we are paying for a sharp finisher who can take 88% to 100% efficiently and cleanly. We're offering $1,500 fixed price for a clearly scoped, well-documented completion sprint. Applicants who try to reprice this into a full rebuild will not be considered. Who We're Looking For → Strong experience with React Native or Flutter (please specify) → Proven ability to inherit and work within existing codebases → Experience integrating third-party APIs (ticketing, payments, or marketplace preferred) → Familiarity with security best practices for high-traffic consumer apps → Clear communicator — we need daily async updates and weekly check-ins → Portfolio or GitHub showing mobile apps you've shipped, not just started To be considered, please include the following in your proposal: 1. A brief overview of a similar project you've completed (inherited codebase or API integration work preferred) 2. Your estimated timeline to complete the remaining scope 3. Your preferred framework (React Native or Flutter) and why 4. Any questions you have about the existing stack Generic proposals will be declined. We're looking for someone who has read this carefully and can speak specifically to the work at hand. READY TO FINISH SOMETHING REAL? The foundation is built. The designs are done. The APIs are live. We need a finisher — someone who delivers, not someone who starts over.
