I will fix bugs and improve performance in your react nextjs vue or nuxt app
Vitalii Vorynka
About this gig
Something is broken or slow in your React, Next.js, Vue or Nuxt app and you need it fixed properly, not patched? I'm a senior front-end developer with 7+ years in production and 2+ years leading a team, where code review and debugging other people's code were part of my daily work.
Typical fixes:
Broken layouts, responsive and cross-browser issues
Hydration errors, state and routing bugs, failing builds
TypeScript errors, dependency and framework upgrades (Next.js, Vue 2 to 3, Nuxt 2 to 3)
Slow pages: bundle size, code splitting, images, caching, unnecessary re-renders, Core Web Vitals
API integration and authentication problems
How it works: you share the repository or a reproducible example, I find the root cause, fix it and explain what was wrong so it doesn't come back. Fixes are delivered as a pull request with a short write-up.
Message me with a description of the problem before ordering so I can confirm the scope and the price. If it turns out to be bigger than one package, I'll tell you upfront.
