Cover Letter
I can start immediately and deliver a fully working, production-deployed platform within 24-48 hours.
I've done exactly this kind of work many times — inheriting near-complete builds and getting them across the finish line. My recent projects include stabilising AI-enabled platforms with Node.js/React/TypeScript stacks, PostgreSQL integration, and production deployment on PaaS platforms like Render, Vercel, and Railway.
Here's what I'll deliver:
DELIVERABLE — Production Stabilisation Sprint:
Phase 1 — Architecture Audit (2-3 hours): • Full codebase review and dependency audit • Map all database → backend → frontend data flows • Validate environment variables and API key configurations • Document current state and identify all breaking points
Phase 2 — Integration & Debugging (6-10 hours): • Connect PostgreSQL ↔ backend ↔ frontend cleanly • Fix routing, authentication, and state management issues • Validate and repair all API integrations • Ensure end-to-end workflow functionality:
- Task creation and persistence
- Calendar management
- Daily briefing generation
- Document retrieval
- Multi-project workload handling
Phase 3 — Production Deployment & Handoff (2-3 hours): • Stabilise Render deployment with proper build/start scripts • Clean up GitHub repository (remove dead code, organise structure) • Updated README with deployment notes and architecture summary • List of any known limitations or recommended next steps
Total: 12-16 focused hours → fully working deployed platform.
I'm available for live collaboration throughout and can communicate on your schedule (I work US Eastern time but am flexible for urgent sprints).
