About this gig
Your Lovable, Bolt or Replit app got you far. Now it crashes, the login breaks, or it won't take payments. I take apps that are 90% there and get them working for real users.
Recent work:
- Took a revision app a founder built with Claude, fixed and redesigned it, and set it up so he can still make changes himself. Student satisfaction rose 70% after the relaunch.
- Rebuilt a broken AI prototype into a production platform that now processes 1.5M documents a month.
What I fix:
- Crashes, blank screens and slow loading
- Broken login, database rules and API connections (Supabase, Firebase)
- Payments and subscriptions (Stripe)
- Messy, duplicated code the AI keeps breaking
- Deployment and hosting so it stays up
I keep your stack where I can, so you can keep building with your AI tool after I'm done.
8 years full-stack (Next.js, React, Supabase, Flutter). Send me your app link and what's broken, and I'll tell you what it will take before you order.

✔ Neo4j knowledge graphs and GraphRAG search where every answer shows its source

FAQ
Do I need to share my source code?
Yes, I’ll need access to your project files or repo to diagnose and fix the issue. Don’t worry, everything stays completely confidential.
How long will it take to fix my app?
Small issues are usually fixed within 24–48 hours, while larger bugs or integrations may take a few days. I’ll always give you an estimated timeline before we start.
Can you add new features or just fix bugs?
Both! I can debug, refactor, or build new functionality on top of your existing app. Many clients start with a bug fix and end up improving their whole product.
