*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.

I’m looking for a developer to help me build a platform that predicts World Cup match results and refines those predictions with real-time data. The project will involve leveraging AI algorithms, machine learning models, historical match data, player stats, and live performance metrics to create accurate match predictions. The platform will need to continuously update and vet these predictions based on new data as the tournament unfolds. If you're passionate about soccer, AI-driven solutions, and real-time systems, this could be an exciting challenge for you. The role will involve developing a scalable platform using technologies like React, Node.js, and possibly Python for data analysis and machine learning. You'll integrate real-time data through APIs to pull match stats and player performance information. AI will be central to the prediction system, with algorithms that analyze historical trends and live data to improve accuracy. You’ll also create a vetting process to ensure predictions remain sharp and reliable as the tournament progresses. The platform must be able to handle high traffic during live events while offering a seamless user experience. I’m looking for someone with experience in AI-based prediction systems, strong web development skills (React, Node.js), and familiarity with working with APIs for real-time data integration. If you have a background in machine learning, real-time data processing, and sports analytics, that would be a major plus.
