About this gig

Stuck on a bug that's blocking your launch? I fix Next.js, React and TypeScript apps, including apps built with AI tools like Cursor, Lovable or Bolt that break when real users arrive.


WHAT I FIX

- Authentication and login errors

- Broken API routes and third-party integrations

- Database and Prisma/PostgreSQL issues

- Vercel and AWS deployment failures

- Slow pages and performance problems


HOW IT WORKS

1. Message me the error, a short description and a link to the app or repo.

2. I confirm I can reproduce the problem before you pay.

3. I fix it, explain the cause and send the changes.


WHY ME

I'm the CTO of VieroMind, a production platform serving 10,000+ users on Next.js, TypeScript and PostgreSQL. I fix problems at the root, not with quick patches.


IMPORTANT

Never send passwords or API keys in chat. I'll ask for a staging copy or a repository invite instead. Larger projects and new features are quoted separately.
