*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.

We are seeking an experienced mobile app developer to create a fully functional MVP that combines social features with an AI chat component. The app should be clean, stable, scalable, and ready for early user adoption, not just a clickable demo. Specific details about the app’s concept and logic will be shared under NDA. This project has a clear roadmap and strong vision for launch, and we’re looking for a thoughtful, skilled developer who can help architect and build a production-ready product with strong user experience, reliability, and performance. Complete UI/UX designs and flows have already been created in Figma, so this role is focused primarily on development, backend architecture, integrations, and implementation rather than design. Preference will be given to developers located in the DC, Maryland, or Virginia (DMV) area for easier collaboration and communication throughout the project, and occasional in-person meetings if needed. Deliverables & Requirements • Develop a cross-platform mobile app using Flutter or React Native • Build secure user authentication, profiles, friend systems, and group chat functionality • Integrate AI chat features via API with moderation and safeguard controls to prevent misuse • Implement reliable push notifications and time-sensitive user interactions across iOS • Set up scalable backend architecture and database infrastructure • Translate existing Figma designs into a polished, responsive mobile application • Conduct testing, debugging, and QA to ensure app stability and performance • Experience with Firebase, Supabase, WebSockets, or similar real-time technologies preferred • Deliver a functional app ready for deployment to the App Store

# Full-Stack AI Engineer — Semantic Search + Next.js + Supabase (Long-Term, Contract-to-Hire) ## About We're building an AI-native platform that makes a large archive of recorded talks genuinely discoverable and useful: need-based semantic search over transcribed media, with a subscription product built around it. We have a clear product vision and architecture and are looking for a lead engineer to build the first version and grow with us long-term. Full product details are shared with shortlisted candidates under NDA — this post focuses on the engineering and the skills we need. ## The engineering challenge You'll build a two-part system that shares one database: 1. **A content pipeline (Python):** ingest recorded talks, transcribe them, chunk and enrich the transcripts with metadata using an LLM API, generate embeddings, and store everything in Postgres. 2. **A web app (Next.js):** fast, crawler-friendly, SEO-strong content pages with structured data; retrieval-based search that returns relevant source material with links/citations; user accounts; and Stripe-gated paid content. We care a lot about retrieval *quality* and clean, maintainable architecture — this is a real product, not a prototype. ## Required tech stack - **App:** Next.js (App Router), TypeScript, Vercel. Strong SSR/SSG, SEO, and JSON-LD structured-data experience. - **AI/backend:** Python; production RAG (embeddings, chunking, retrieval quality); LLM API integration. - **Data:** Postgres + **pgvector** (via Supabase); embeddings via a hosted model (Voyage/OpenAI). - **Auth & gating:** Supabase Auth with row-level security. - **Payments:** Stripe (subscriptions + one-time). ## Required skills - Shipped production Next.js (App Router) + TypeScript apps with strong SSR/SEO. - Built a real RAG / vector-search system in production — not a tutorial clone. - Comfortable in Python for data pipelines. - Postgres + pgvector and Supabase in production. - Stripe integration. - Plans before building; communicates clearly in writing. ## Nice to have - Audio/video transcription experience (Whisper / faster-whisper / Deepgram / AssemblyAI). - Agentic coding workflows (e.g., Claude Code). - Content-heavy SEO products or media libraries. ## Engagement - Hourly, contract-to-hire. ~20–40 hrs/week to start; long-term for the right person. - We start finalists on a **small paid test project** (a single self-contained slice of the pipeline) before the full engagement — that's how we evaluate fit. ## Confidentiality This is a proprietary product. Shortlisted candidates sign a mutual NDA before we share full scope and context. Please don't expect complete product details in the first exchange — strong technical applicants will have everything they need to be evaluated, and the rest follows the NDA. ## How to apply Applications that skip these are ignored: 1. **Start your proposal with the word `pgvector`** so we know you read this. 2. Link **two** projects: one live Next.js/SSR app, and one RAG/embeddings or LLM-integration project. Tell us what *you* personally built. 3. Answer briefly: *An offline embedding pipeline and a live search query must use the same embedding model — why does that matter, and how would you guarantee it?* 4. One line on your approach to chunking long-form audio/video transcripts for good retrieval.

Senior Full-Stack Engineer — Canvas Medical EHR Lead Contract · Monthly retainer · Remote (US-based) · Ongoing -= DONT APPLY IF =- Not physically present in USA you're an AGENCY. I need 1 person. no middleman Generalists and "I can pick up Rails" applicants will not be a fit. If we can't see your projects on github dating back years (temp) you're not serious. Anyone who's thinking of making someone else do the work, go away. No time for games. Summary I'm hiring a senior full-stack engineer to lead the build-out and launch of a longevity-medicine platform: B2B formulary ordering for licensed providers, plus a patient prescription and reorder portal, built on Canvas Medical (a programmable, ONC-certified EHR). The design and product logic are set. I need someone who configures the EHR, builds the integrations, finishes the frontend, ships it, and keeps it running. This is not a learn-on-the-job seat. It is a finisher seat. What you'll own Configure and extend Canvas Medical to the prescription, formulary, and patient-portal workflow by writing Python plugins on the Canvas SDK Integrate the platform over the Canvas FHIR (R4) API, including provider registration, ordering, billing, and the patient portal Finish and ship the product frontend and bind it to the API Handle deployment, uptime, and ongoing monthly support and iteration after launch Stack Python (Canvas SDK plugins run inside the EHR) Canvas FHIR R4 API (FastAPI-based); Django ORM for data access Frontend: finishing an existing web frontend and wiring it to the API Healthcare data handling under HIPAA Must have Senior-level Python. Non-negotiable. The SDK is Python. Hands-on FHIR / healthcare data integration. This is the differentiator and the first thing I screen for. Experience with Canvas Medical or a comparable EHR or health-data platform (Medplum, Redox, Health Gorilla, or similar) HIPAA and PHI handling experience. This is a live EHR with patient data, not a storefront. Frontend competence to finish a web app and connect it to a REST/FHIR API A track record of shipping. Links to live work, not a list of frameworks. Strong async communication and reliable follow-through Nice to have Direct Canvas SDK plugin experience (Events, Data, Effects) Prior digital-health, telehealth, or pharmacy-tech product work Experience taking a stalled or unfinished product across the finish line Engagement Contract, paid on a monthly retainer Remote, US-based for this lead role Long-term: build phase first, then ongoing support. I'm looking for a durable relationship, not a one-off. To apply In your reply, include: Links to things you've shipped, FHIR and EHR work prioritized One example of a project you took from stuck to done, and what you did? Whats your favorite car? Your monthly availability in hours? Thanks

We’re seeking a full-stack developer to help build a SaaS MVP using TypeScript and Next.js. The platform will center around a PostgreSQL-backed system with user authentication, role-based access control, asset tracking, inspection logging, and photo upload functionality. This is a data-driven product, so experience designing clean, scalable database structures and building reliable backend workflows is important. As part of the initial phase, we plan to launch a beta using Airtable to validate workflows and refine the data model before transitioning to a fully custom build. Experience working with Airtable or integrating it into early-stage products is a strong plus. We’re looking for someone who has solid experience with TypeScript and Next.js, can move efficiently, and is comfortable working on an evolving product. The goal is to have a functional MVP completed within the next three months. This isn't a hard deadline, if our goal is ambitious let us know and we can discuss.

We're building a data-driven platform in the beauty/cosmetics space. We've already collected a very large volume of scraped product and brand data, and it's messy - inconsistent formats, duplicates, missing fields, mixed languages, and unreliable values. Your job is to turn that raw data into something clean and reliable, and to build the web application on top of it. This is not a quick gig. We're looking for someone to stay with us for roughly a year and grow with the product. What you'll be doing Building and maintaining a Next.js (App Router) front end and back end Designing and managing our Supabase setup (Postgres schema, RLS policies, auth, storage, edge functions) Cleaning, normalizing, and deduplicating large beauty datasets (this is a major part of the role) Building data pipelines to process and validate incoming scraped data Writing transformation/normalization logic (units, brand names, categories, ingredients, pricing, etc.) Setting up data-quality checks and monitoring Iterating on features with us as the product evolves You should have Strong production experience with Next.js and Supabase (please point to specific projects) Solid SQL/Postgres skills - not just ORMs Real experience cleaning and normalizing large, messy datasets (Python/pandas or similar is a plus) Comfort working with scraped data and all the inconsistencies it brings Good written English and reliable communication Ability to work independently and own your part of the product Nice to have Experience in e-commerce, catalog, or product-data projects Familiarity with data pipelines / ETL tooling Some ML/NLP experience for entity matching or text cleanup Budget We expect this to run around $4,000–$5,000 USD per month depending on experience and hours. This is a long-term commitment, so stability and quality matter more to us than the lowest rate. To apply, please include: Similar past work - links or short descriptions of Next.js + Supabase projects, and at least one data-cleaning/normalization project you've done. Your time zone and your typical available hours - we need to know there's reasonable overlap. Your expected monthly budget within the range above (or your rate if hourly). Applications that don't address all three points will not be considered. A short note on how you'd approach cleaning messy beauty product data is a big plus. We read every proposal carefully and respond quickly to strong candidates. Looking forward to working with you.

We are building a semiconductor manufacturing intelligence platform designed to help engineers rapidly identify yield excursions, investigate root causes, and capture institutional process knowledge. A working foundation already exists, including yield dashboards, lot tracking, process-route visualization, maintenance-event correlation, and investigation timelines. We are now looking for a highly capable developer to extend and refine the system into a production-grade engineering decision-support tool. This is not a basic dashboard project. The goal is to enhance an existing platform into a system that connects manufacturing data, equipment history, and engineering knowledge with lightweight AI-assisted analysis. Key Objectives Help engineers answer questions such as: * Why did yield drop? * What changed before the excursion started? * Which tools or chambers are most likely responsible? * Have we seen a similar issue before? * What corrective actions worked previously? Scope of Work Investigation Workspace * Improve investigation timelines * Correlate process events, SPC/FDC signals, maintenance activity, and yield changes * Enhance interactive debugging workflow Historical Excursion Search * Simple similarity matching using rules or embeddings/API-based methods * Retrieve past investigations and outcomes Engineering Knowledge Layer * Searchable notes, documents, and reports * Store corrective actions and process changes AI-Assisted Summaries (lightweight) * Generate investigation summaries using an LLM API * Suggest possible contributing factors based on available data Ideal Candidate * Strong full-stack or data engineering experience * Comfortable working with existing codebases * Experience with analytics dashboards or industrial systems * Familiarity with APIs, databases, and data modeling * Bonus: exposure to manufacturing or semiconductor data Notes * This is an extension of an existing platform, not a rebuild * Focus is on practical implementation rather than complex architecture * Speed and execution matter more than theoretical design * Potential for ongoing work if collaboration goes well
