About this gig
Have a bug, rough feature, or hard-to-follow codebase? I use Claude Code with professional engineering review to debug and improve web applications. I can fix bugs in Node.js, React/MERN, Laravel/PHP, and other web projects; implement scoped features and API integrations; refactor code; add or repair tests; investigate performance issues; and set up practical AI coding workflows. Basic covers one small bug or one API integration. Standard covers up to 3 related bugs or one small feature, plus up to 3 API integrations. Premium covers one scoped feature or complex bug, up to 5 API integrations, tests, and workflow setup. Delivery follows the selected package. To start, share sanitized files or repository access, language/framework versions, error logs, reproduction steps, and the expected result. Never share passwords, API keys, access tokens, or production customer data. Message me first for large codebases, urgent work, or unclear requirements.

FAQ
What languages and frameworks do you support?
I work with Node.js, JavaScript/TypeScript, React/MERN, Laravel/PHP, and other web stacks. Share your framework and version so I can confirm the scope.
What do you need to get started?
Please share sanitized source files or repository access, the relevant error/logs, steps to reproduce, expected behavior, and any test instructions. Remove credentials and production customer data.
How do you use Claude Code safely?
Claude Code assists with analysis and implementation; it does not replace engineering review. I review generated changes, run relevant tests where practical, and report any remaining limitations.
