*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 .NET developer for a short-term, focused engagement to resolve a specific bug in a legacy medical application currently in production. This is a well-scoped project lasting approximately one to two weeks, ideal for someone who can quickly navigate older codebases and deliver a reliable fix without introducing regressions. The ideal candidate must have strong hands-on experience with .NET Framework 4.x, C#, and either WinForms or ASP.NET WebForms (depending on the application stack), along with proficiency in SQL Server for debugging stored procedures and queries. Familiarity with VB.NET is a plus, as the codebase may include mixed syntax. You will be responsible for reproducing the issue, identifying the root cause, implementing a clean and minimally invasive fix, and performing basic regression testing to ensure system stability. Given the critical nature of this application in a healthcare setting, attention to detail and documentation of changes for internal review and compliance traceability are essential. Prior experience with medical or healthcare IT systems is highly valued, as is any understanding of HIPAA, FDA software validation, or GxP requirements. We offer a fully remote, flexible engagement with quick onboarding, clear acceptance criteria, and access to the codebase, database schema, and test environment upon start. If you have successfully handled similar bug-fix or maintenance tasks on legacy systems, please reply with a brief summary of your relevant experience, availability, and hourly or project-based rate. Successful delivery may lead to additional follow-up work.

We are looking for a U.S.-based senior React/Firebase technical lead or software architect to help review and guide an existing SaaS product to pilot launch. The product is already built and deployed in staging. This is not a greenfield build. We need an experienced technical partner who can inspect the current architecture, review contractor work, identify launch risks, and help sequence the remaining work before pilot. Current stack: * React / TypeScript * Firebase Auth * Firestore * Firebase Storage * Firebase Cloud Functions * Firebase Hosting / GCP * GitHub The app is a multi-tenant SaaS platform with organizations, locations, employees, role-based permissions, training modules, SOPs, communications, request-off workflows, handbook acknowledgements, and admin consoles. We need help with: * Reviewing the existing React/Firebase architecture * Reviewing Firestore rules, Storage rules, Cloud Functions, auth/custom claims, and tenant isolation * Reviewing PRs and contractor work * Advising on remaining pilot-readiness work * Helping sequence frontend cleanup, UX/UI polish, admin console structure, and final security review * Identifying risks before real pilot customers are onboarded Important experience: * React + TypeScript SaaS applications * Firebase Auth / Firestore / Cloud Functions * Multi-tenant architecture * Role-based access control * Security-minded code review * GitHub branch / PR workflow * Ability to explain technical tradeoffs clearly We would like to start with a small paid technical review first. If it is a good fit, this may turn into an ongoing technical lead/advisor role. We are not looking for someone to blindly rebuild the app. We need senior judgment, architecture review, launch-risk identification, and practical guidance.
