About this gig

Half-finished Next.js app, a developer who disappeared, or a bug nobody can find? I'll pick up your code and get it done.


I build Next.js apps with Node.js, PostgreSQL and Supabase from database to screens. Recent work includes an online store live in three languages and a catalog site with an admin panel, both built end to end.


What I can do:

  • Fix bugs in pages, API routes and server actions
  • Supabase auth, database, storage and edge functions
  • Build a missing feature end to end: payments, dashboards, search
  • Speed up slow pages and fix SEO basics
  • Deploy on Vercel and hand over clean, documented code


How it works:

  1. Tell me what's broken or what's missing
  2. I reply with a plan and a fixed price
  3. I deliver in your repo, with a short summary of what changed


Happy to work with code written by other developers or AI tools like Cursor, v0 or Lovable.

I'm a React Native and full-stack TypeScript developer from Estonia, freelancing since 2021. Three apps I worked on are live on the App Store and Google Play, and since 2024 I've been the lead developer of Cocopine, a parental control app for YouTube. Most of my work is fixing apps that got stuck: crashes, broken builds, store rejections, or an AI-built app that works in the demo but breaks for real users. Send me a short description of the problem. I'll tell you what's wrong and what it costs before you order.
