About this gig

Your app breaks, a deploy fails or a feature is stuck? Tell me what you need help with. I reproduce the problem, fix it and explain the cause so it does not come back.


I work with React, Next.js, TypeScript, Node.js and Firebase (Auth, Firestore, Functions, Hosting).


How it works:

  1. You share read access to the repo and the steps to reproduce the problem.
  2. I confirm in writing what is included and the delivery time.
  3. I fix it in a separate branch and send a short summary of the changes.
  4. You test it and I adjust whatever you flag.


Not included: full rewrites, projects without source access and design changes outside the fix.

I build custom admin dashboards, internal business tools and web apps with React, TypeScript, Node.js and Firebase, plus REST APIs with Java Spring Boot.
