I will rescue and fix your lovable, base44 or replit app bugs
Qasim
About this gig
Your app worked in the Lovable or Base44 preview. Then a real user signed up and your entire Supabase database was wide open because row level security was never configured. Or your auth flow locks people out. Or Stripe won't go live. Prompting the AI tool again makes it worse.
I step in as a full-stack engineer (Next.js, React, Supabase, Node) working specifically on apps that already exist, not from-scratch builds, so I'm fast at finding the real root cause in someone else's (or an AI's) code.
What I fix: broken auth/login flows, logic errors, UI bugs that only show up for real users, broken database queries, state issues, and anything that worked in preview but fails in production.
How I work: Send me your app link and what's breaking I'll tell you exactly what's wrong and what it'll take to fix it, before you order.

I'm Qasim, a full-stack engineer (Next.js, TypeScript, Supabase, Node) who works specifically with apps already built on Lovable, Replit, Base44, or Bolt — taking them from "works in the preview" to a real, secure, production-ready product.
Top Rated on Upwork (100% JSS) shipping production apps for founders — including a real-time multiplayer SaaS built in two weeks and an enterprise job-tracking platform now running with 60+ active users.
I fix bugs, connect Stripe/Supabase/APIs properly, and deploy with a security pass before real users arrive.
FAQ
Do you fix bugs in Lovable apps even if I didn't build it with you?
Yes — most of my clients are fixing apps Lovable, Replit, Base44, or Bolt generated, that I had no part in building.
Do I need to give you full code access?
A live preview link plus a clear description of the bug is often enough to start. For deeper issues I'll ask for GitHub/Lovable/Replit access.
What if the bug turns out to be bigger than expected?
I'll tell you before doing extra work — you'll never be surprised by scope creep.
Can you fix Supabase RLS or auth bugs specifically?
Yes, that's one of the most common issues I see in Lovable/Base44 apps — auth flows and Row Level Security misconfigurations.
Do you offer ongoing support after the fix?
Yes, ask about a retainer once your app is stable — many clients move to ongoing support as they keep building.
