Features
- Fastify, Prisma, PostgreSQL and Supabase API paired with a Next.js 15 and TanStack Query frontend, deployed on Vercel and Railway.
- Designed an AI-agent engineering harness: a curated skill library, four automated code-review subagents covering correctness, security, database, and types and tests, plus machine-readable conventions.
- Built a spec-driven, subagent-orchestrated execution loop, from planning to checkbox-tracked tasks to automated review, running in isolated git worktrees, enabling the client to ship code through Claude Code and Codex.
- Used Claude Design to co-iterate the UI/design system with the client from prototype to production.
