Fix one reproducible JavaScript or TypeScript bug, with a focused patch and tests that demonstrate the agreed behavior. This is AI-assisted work for a small, clearly scoped module—not a new application or an open-ended support engagement.

For US$150, the agreed package includes one code patch, 1–3 regression tests, a short README with setup/run commands and observed test results, and one correction round against the original acceptance criteria. Delivery is as source/patch files; a pull request is optional when appropriate repository access is available.

Before booking, send a sanitized repository or minimal example you are authorized to share, the current and expected behavior, reproduction steps, and test commands. We first confirm that the issue fits this package, agree the acceptance criteria and timeline in writing, and confirm that AI assistance is acceptable. Do not send secrets, production credentials or personal/customer data.

The listed one-week duration is an estimate after the agreed start and receipt of reproducible inputs, not a promise of immediate availability. Larger changes require a separate quote. New apps, production deployment, security audits, penetration testing, mobile-store releases and ongoing maintenance are excluded.

My work samples are self-directed Mercy Key projects, not paid client case studies. A synthetic Node.js demonstration with 15 checks is available from https://mercy-key.codex507411.chatgpt.site/readiness-review#sample-review . Passing checks cover only the tested behavior; they are not a guarantee of production safety.
