I rescue one reproducible blocker in an AI-built or conventional web app: authentication, API, database, runtime, or deployment.

You get: • root-cause note • one bounded, tested fix in your repository • regression tests • setup and handoff runbook • one revision

Best fit: Python/FastAPI, TypeScript/Next.js, Supabase, APIs, Docker, and Playwright. Delivery is AI-assisted, reviewed, and accepted against clear criteria.

Not included: a new product, a full redesign, or multiple unrelated features. Sensitive client code is used only with permission. Public portfolio items are self-initiated technical demonstrations, not paid client work.
