About this gig

Is your React app throwing errors, showing a blank page, or behaving strangely? I find the root cause and fix it without breaking anything else. I work daily with React and TypeScript and have 10 years of full-stack experience. I handle console errors and failed builds, broken state, props and hooks logic, API data not loading or showing wrong, layout breakage after updates, and slow renders. How it works: send repo access or a minimal reproduction plus a description of the bug. I reproduce it first, fix it, and show before/after verification.
