Develop Reverse Marketplace App lovable project polishing
Budget: $250 – $750 USD
Own the last mile: fix core flows, harden the codebase, and publish to iOS and Android. Set up daily automated tests so the app stays shippable.
Current stack
Frontend: Next.js + React, TypeScript, Vercel
Backend: Supabase (Postgres, Auth, Realtime, Storage, Edge Functions)
Infra: Vercel + Supabase
Built initially on lovable.dev
What’s broken vs working
Works: listing cards and browsing
Not working: messaging, transactional flow
Goal: get messaging and payments live, stabilize app, submit to stores, and wire CI with tests
Scope of Work (you own end-to-end)
Productization and polish
Audit repo, remove lovable.dev scaffolding debt, align file structure, add env management
Resolve iOS Safari caching issues, PWA service worker sanity, and performance regressions
UX pass on listing cards, empty states, error states, loaders, and optimistic updates
Messaging that actually ships
Implement real-time 1:1 messaging via Supabase Realtime
Features: unread counts, typing indicator, attachments via Supabase Storage, basic moderation/report
Edge cases: reconnect, offline queueing, duplicate message guards, idempotent writes
Transactions that clear
Implement Stripe Connect Standard (or Express if needed) with webhooks
Flows: create intent, hold funds at accept, capture on completion, refund/cancel paths
Receipts, fees, tax settings, payout to sellers, idempotency keys, webhook signature verification
Basic dispute hooks and audit logs
App Store delivery
Pick a pragmatic path and execute:
Option A fast track: Capacitor wrapper for iOS/Android + PWA hardening + TWA on Android
Option B cleaner native shell: Expo + WebViews for transactional screens you rebuild natively
Deliverables either way:
iOS: App Store Connect setup, bundle IDs, signing, TestFlight build, App Privacy details
Android: Play Console setup, keystore, internal testing track
Store assets: icons, screenshots, short and long descriptions, privacy policy link
Quality gates and CI
Unit tests: Vitest + Testing Library for components and hooks
E2E: Playwright across desktop and mobile viewports; stub Stripe/Supabase where needed
API tests: Edge Functions with supertest or fetch-based harness
CI: GitHub Actions with nightly cron, on-PR runs, flaky test quarantine, artifacts
Observability: Sentry for FE/BE, PostHog or Plausible for product analytics
Security and compliance basics
Role-based access checks server-side, not just client
Input validation and Zod schemas at boundaries
Secrets in Vercel/Supabase, rotate keys, principle of least privilege
Stripe PCI scope minimized, webhook retries handled idempotently
Privacy policy + terms templates integrated into app
