I fix one small, reproducible bug in a React/TypeScript frontend or Python script. Scope: one issue in a supplied repository, up to 3 changed files and one focused regression test, with a concise explanation and one revision. Please share a minimal reproduction, expected behavior, repository access, and test command before ordering. I use AI-assisted development and verify changes locally. The price covers diagnosis and an agreed small fix; larger features, production deployment, credentials, and live financial transactions require a separate quote. I start only after scope, acceptance criteria, delivery date, and USDT escrow funding are confirmed.
