Something broken or slow on your React or Next.js site? Send it to me and I will find the cause and fix it.

Typical jobs: a page that crashes or shows a blank screen, a build that fails, a form or API call that stops working, hydration and rendering errors, a slow first load, large bundle sizes, layout that breaks on mobile, or a site that scores badly on Lighthouse.

What you get: I reproduce the problem, fix the root cause rather than patch over it, and send you a short note explaining what was wrong and what I changed. Small related cleanups are included.

How it works: share the repo or hosting access and a description of the problem. I confirm whether it fits this service before you pay. If the work turns out to be larger than a bug fix, I will tell you up front and quote separately.

I have solved over seven hundred problems on Codeforces and HackerRank, and debugging is the part of this job I enjoy most.
