Resolve a reproducible JavaScript, TypeScript or React issue with a focused, reviewable patch. I work on UI behavior, component state, API calls, type errors and build problems.

Deliverables include the changed source or a pull request, an explanation of the cause, relevant tests or browser checks, and handover notes. We agree on one issue, acceptance criteria, price and turnaround before work starts.

Send the repository, framework versions, expected behavior and reproduction steps. Small fixes can move quickly. Larger features, upgrades, performance investigations and ongoing maintenance can be scoped into milestones.

Related tools include Node.js, HTML/CSS, Vite, SQL, Cloudflare Workers and GitHub Actions. Deployment and unrelated changes are separate unless included in the agreed scope.
