Backend: Go • Echo • PostgreSQL • Node.js • Express • MongoDB Frontend: React • React Native • TypeScript/JavaScript • TailwindCSS DevOps: Docker • Linux • Railway • Vercel AI Tools: Claude Code • Cursor — daily development workflow
Real-time shared expense tracker for couples, architected from a complete Technical Requirements Document before implementation began. Includes a live architecture decision log (ADRs) and technical debt register maintained alongside the code.
- Go + Echo backend, strict layered architecture (Handler → Service → Repository) — client never touches the database directly
- React Native + Expo (bare workflow), TypeScript strict mode, PostgreSQL via Supabase
- All financial amounts stored as integer cents (int64) — avoids float precision errors in money handling
- Full spec and decision log available on request
Stack: Go, Echo, React Native, TypeScript, PostgreSQL, Supabase
