Freelance AI App Developer & Bug Fixer
Upwork • ZZP
Nov 2025 - Present • 9 mos
Debug and repair full-stack apps built on AI no-code platforms including Lovable, Base44, Bolt, Replit, and v0. Work spans fixing broken app logic after AI-generated edits, securing Supabase databases (Row Level Security, auth bypass patches), resolving failed deployments, migrating apps off no-code platforms to custom stacks (Next.js, Supabase, Expo), and fixing Stripe webhook and n8n automation failures. Focus on diagnosing root causes in AI-generated code rather than surface-level patches.

I actually got emotional seeing my app live on the Play Store, this idea sat in my head for months and I never thought it would become real. She didn't just do a job, she made something I'll never forget happen. Thank you for believing in this with me

This seller is exceptional, truly perfect! Fast delivery, amazing communication, and she went above and beyond the whole time, honestly more than I expected. I can't even express how happy I am with the result, seriously top tier work. Would 100% work with her again, no doubt about it
