Ilia Kolodin
About this gig
Hi, I'm Ilya a Software Engineer with 5+ years of commercial experience building and fixing production apps in JavaScript, TypeScript, React, Next.js and Node.js.
Got a bug that's driving you crazy? A broken build, a crash, a failing API, a layout that won't behave, or an error you can't trace? Send it to me and I'll fix it fast and explain what went wrong.
WHAT I CAN FIX:
- React / Next.js errors, hooks, rendering, hydration and routing issues
- Node.js, NestJS, Express APIs, crashes and logic bugs
- TypeScript type errors and build failures
- REST / GraphQL, database and async bugs
- Broken UI, CSS and responsiveness
WHY ME:
- 5+ years shipping real production code
- Clean, tested fixes, not quick hacks
- Clear explanation of the cause so it won't happen again
- Fast, friendly communication
I'm new on Fiverr, so prices are low while I build my reviews you get senior-level help at a starter price.
Please message me with your bug before ordering and I'll confirm I can solve it. Let's get your code working again!
