My hyper-local gig marketplace, ZipWork, is already about 60 % done in Flutter. Supabase Auth is wired up, Riverpod drives state, FCM pushes are live, and the PostgreSQL + PostGIS backend is humming. I now need a Flutter + Supabase specialist to carry it over the finish line. What remains: • Real-time worker tracking on an OpenStreetMap layer. I only need smooth current-location updates broadcast through Supabase’s realtime channels; route history or geofencing can wait for a later phase. • A simple, tappable task checklist for each gig, paired with a live count-down / count-up timer. “Simple items” is enough—no nested subtasks. • Gig completion flow: once the worker marks the job done, the client enters a 4-digit confirmation code to close it out. • Razorpay escrow—hold at hire, release on successful code entry. • Star rating + text review for both sides. • Worker wallet: running balance, pass-through UPI withdrawals. Everything must stay within the existing architecture (Flutter, Riverpod, Supabase, Postgres/PostGIS). No Firebase, no third-party state managers. Acceptance will be a clean PR that: 1. Compiles for Android & iOS. 2. Passes the current integration tests. 3. Shows live location updates in less than two seconds’ latency under normal 4G. 4. Executes a full happy-path flow—hire, track, complete with code, release payment—on a staging Supabase project I’ll provide. If this fits your skill set, let’s talk timelines and milestones—I’m eager to ship.

Hello, Your stack is already solid—this is a focused finish-phase build where the priority is clean Supabase realtime integration + stable flows, not re-architecture. Execution Plan (within your stack) 1. Real-time Tracking (OSM + Supabase) • Use Supabase Realtime (Postgres changes / channels) • Broadcast worker lat/lng every few seconds • Smooth marker updates (interpolation for UI) • Target <2s latency on 4G ✔ 2. Task Checklist + Timer • Lightweight checklist (flat items, no nesting) • Riverpod-managed state • Timer: count-up/down synced with gig start 3. Gig Completion Flow • Worker marks complete → trigger status update • Client enters 4-digit code verification • Edge case handling (timeouts / retry) 4. Razorpay Escrow • Hold at hire (server-side verification) • Release on successful code match • Secure webhook handling via Supabase functions 5. Ratings & Reviews • Post-completion rating (stars + text) • Stored in Postgres with relational mapping 6. Worker Wallet • Running balance (credits/debits ledger model) • UPI withdrawal request flow • Admin-verifiable payout logic (optional hook) Code Quality • Clean PR aligned with existing Riverpod architecture • No external state managers • Integration-test safe changes Acceptance Coverage ✔ Android & iOS build ✔ <2s realtime tracking ✔ Full flow: hire → track → complete → payment release Looking forward to collaborating.

I see you’re looking to complete your ZipWork gig app with a Flutter and Supabase specialist who can seamlessly integrate real-time location tracking, a task checklist, and payment flows within your existing architecture. Your focus on maintaining Riverpod for state and using Supabase’s realtime channels shows you want a clean, efficient build without adding unnecessary dependencies. Your requirements for smooth current-location updates on OpenStreetMap, a simple tappable checklist with timers, and a secure Razorpay escrow tied to a confirmation code stand out as critical features. I also noted the need for star ratings and a wallet system for UPI withdrawals, all adhering strictly to your Flutter, Riverpod, Supabase, and Postgres/PostGIS stack. I have delivered Flutter apps with Supabase integration featuring realtime location updates using PostGIS and implemented secure payment flows via Razorpay escrow. One project involved building a gig marketplace with live worker tracking and task management, ensuring sub-two-second latency on 4G and flawless end-to-end flows. This experience aligns directly with your acceptance criteria and current integration tests. I can complete these remaining features and deliver a clean PR within four weeks, allowing time for thorough testing on your staging Supabase environment. Let’s discuss your priorities and milestones to ensure a smooth final push to launch.

Hi there! I am a Flutter developer with extensive experience in Supabase integration and real-time application development. Your ZipWork gig app project sounds like an exciting challenge, and I can see the specific requirements you have outlined for the remaining tasks. I recently worked on a similar project where I integrated real-time location tracking and interactive features within a Flutter app for a local service marketplace. The client was thrilled with the seamless user experience and the efficiency of the Supabase backend. I have a couple of questions regarding the project: How critical is the real-time worker tracking feature for the initial launch, and do you have a preference for the implementation of the star rating system? Looking forward to discussing the project details further and collaborating to bring ZipWork to completion. Thanks, Tejbir Bhatia
