A scoped feature, integration, or fix in your existing React, Next.js, or Node codebase, finished and deployed.

Included: one feature or integration such as auth, payments, webhooks, third-party APIs, or dashboards, or one release-blocking fix; reproduction, implementation, tests on affected paths, deployment with rollback notes, one scoped revision, and seven days of regression support.

You provide repository access, a safe test environment, and one clear acceptance test in writing. Open-ended maintenance, large migrations, and security incident response are outside this scope.
