Executive summary
A two-sided marketplace where sellers list pets with photos, videos and health records, and buyers either place competitive bids or buy at a fixed price. Alongside it, a curated storefront for pet food, accessories and grooming, plus a directory of local vets with contact numbers and addresses. One product, four surfaces: buyer/seller mobile apps, a public website, and an internal admin console for moderation, commerce and support.

Roadmap
Delivery schedule for the full scope quoted below, compressed into a ~16-week build with most modules running in parallel.
Discovery, requirements & architecture
Wk 1Product backlog, technical architecture, database schema, sprint plan.
UI/UX design
Wk 1–3Wireframes, design system, high-fidelity screens across app/admin/web, clickable prototype.
Backend foundation
Wk 2–4Auth, user & role management, core APIs, cloud infrastructure and CI/CD pipeline.
Bidding & auction engine
Wk 3–7Real-time bid service, auto-bid, outbid notifications, listing fraud checks.
Pet-needs marketplace
Wk 5–9Product catalog, cart, checkout, order management.

Wk 6–7Vet listings with contact numbers and addresses, search, admin-managed entries.
Payments, wallet & escrow
Wk 6–8Gateway integration, wallet ledger, bid-win escrow and seller payouts.
Flutter app build — iOS & Android
Wk 2–14Single Flutter codebase across all modules, running parallel to backend delivery, with native polish passes.
Admin panel
Wk 9–13Moderation, KYC review, disputes, analytics dashboard.
Website

Fitting the full scope into 16 weeks means running a larger, more parallelized team from the start — the Flutter build kicks off in week 2 alongside backend work, and QA runs continuously per module rather than only at the end. A 60-day post-launch bug-fix window follows outside this 16-week build (see Assumptions & exclusions).
Tech stack
A single Flutter codebase for iOS & Android, paired with a modular backend that keeps the real-time bidding path isolated from the rest of the system.
Mobile apps
Backend & real-time
Data & storage
Payments & identity
Admin & website
Cloud & DevOps
QA & monitoring
