We are looking for a highly experienced Flutter engineer and technical lead to perform a hands-on assessment of an existing mobile and web platform and help determine the fastest path to production readiness and revenue generation. This is not a typical feature-development project. We need someone who can review the mobile application, web portals, backend integrations, payment workflows, and overall user experience to identify what is working well, what still needs attention, and what should be prioritized next. A key part of this engagement is manual testing. We are looking for an engineer who will personally use the platform, test end-to-end workflows, and evaluate the product from the perspective of real users rather than relying solely on automated tools or AI-generated analysis. We also have a previously deployed mobile application that may provide a faster path to market. We want your assessment of whether enhancing that application, particularly around payments and subscriptions, could accelerate near-term revenue while the broader platform continues to mature. Please tell us: Your experience launching production Flutter applications Your experience in inheriting and improving existing codebases Your approach to evaluating production readiness Your experience with payment and subscription workflows Why do you believe you would be a good fit for this engagement Project Scope Overview: https://docs.google.com/document/d/10nZeqKWI-LqCewEM2vEuNvC70QW4g-D_VnIbDhQS4bY/edit?usp=sharing

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.

This is a Flutterflow app called CARS which stands for Cybersecurity Awareness & Resilience Solution. I am a Phd student at NSU and I will be engaging in developmental research for microbusiness owners testing cyber awareness and resilience for their microbusinesses. This is intentionally a minimal research app. There is no backend all logic is handled in FlutterFlow + Firestore. The app enforces sequential viewing of videos and tracks completion and rewatch behavior only. The focus is on simplicity, reliability, and clean UX. Avoid over-engineering. There are 102 videos that have already been loaded via csv via Rowy into Firebase/Firestore. You already have: videoId title module order videoUrl and the videos are set-up to play sequentially one after another. If you get the job, I will provide the csv with placeholders for videourl for privacy. Please review the attached Developer Brief to get an idea of the specifics of this job. Thank you.

I am launching a phonics-based reading tutoring app for young children (primarily K-2). The goal is a hybrid platform that combines engaging digital lessons with in-person/virtual tutoring capabilities. We need a skilled full-stack mobile developer (or small team) who is highly proficient with AI coding tools to build a polished MVP quickly and cost-effectively. Project Overview Build a cross-platform app (iOS, Android, and web-responsive) focused on systematic phonetic reading instruction. Students will learn letter sounds, blending, decoding, and reading decodable texts through interactive, gamified activities. Tutors/parents will manage sessions, track progress, and conduct in-person or video lessons. The emphasis is on speed to market using AI tools while ensuring clean, maintainable code. Key Features for MVP (Prioritized): • Digital Learning Core: • Phonics curriculum modules (letter sounds, CVC words, digraphs, blending drills, decodable stories). • Audio playback for correct pronunciation + simple speech recognition for practice/feedback. • Interactive exercises, games, progress tracking, badges/levels, and adaptive paths. • Kid-friendly UI with visuals (mouth shapes, animations). • Hybrid Tutoring Features: • Calendar/scheduling system for in-person or virtual sessions. • Video call integration (Zoom or similar). • Session notes that sync to student progress dashboard. • Parent/tutor dashboards with reports. • Backend & Essentials: • User accounts (students, parents, tutors). • Secure data storage and basic analytics. • Payments/subscriptions (Stripe integration preferred). • Compliance basics (COPPA/GDPR for kids’ data). Tech Stack Preferences (Flexible): • Cross-platform: Flutter or React Native. • AI tools mandatory for acceleration: Cursor, Claude Code, GitHub Copilot, v0, or similar. • Backend: Firebase/Supabase or lightweight Node.js. • Integrations: Audio/speech APIs, calendars, video. Timeline & Deliverables • Target Launch: Q3 2026 (aggressive but achievable with strong AI usage). • Phase 1 (2–3 weeks): Detailed specs, wireframes, core architecture. • Phase 2 (4–6 weeks): Core digital phonics features + backend. • Phase 3 (2–3 weeks): Hybrid scheduling/video + testing/polish. • Final testing, app store submission, and handover. Total estimated: 8–12 weeks for a functional MVP. Milestones with payments. I can provide initial wireframes/specs or collaborate closely. What I’m Looking For: • Proven experience building educational or gamified mobile apps (portfolio required). • Strong proficiency with AI coding tools (Cursor/Claude Code preferred) to generate, iterate, and debug code rapidly. • Ability to deliver clean, scalable, production-ready code — not just AI-generated output. • Experience with speech/audio features, user authentication, and third-party integrations. • Excellent communication, proactive problem-solving, and ability to work independently. • Bonus: Background in EdTech, phonics/literacy apps, or working with children’s products. Budget: Fixed-price preferred. Hourly also considered for the right candidate. Please include your realistic timeline and total cost estimate in your proposal. To Apply: Please reply with: 1. Links to 1–2 similar apps you’ve built (especially EdTech or mobile learning). 2. Your experience level with AI coding tools (e.g., “I ship features 2–3x faster using Cursor + Claude”). 3. Estimated timeline and budget for this MVP. 4. Any questions about scope. Serious applicants only — I’m ready to start immediately.

We are looking to do a new build of our patch bay label designer tool. Customers are currently able to pick their model of patch bay, add text labels, colorize, and group. They can then checkout and it creates print ready artwork for our team to produce. The UI is a bit clunky and there are some features we want to add such as an admin tool to add and edit labels. You can see the current tool here: https://create.traceaudio.com/
