Backend Developer: Supabase, PostgreSQL And Database Security
Pakistan
Inglese, Urdu
Chi sono
I build and secure Supabase backends, mainly fixing the Row Level Security gaps that AI coding tools like Lovable, Bolt, and Cursor tend to leave open. I'm a Computer Science student at LUMS specializing in Cybersecurity, and I built GymELO, a fitness app with a production Supabase backend where I set up RLS policies and made sure sensitive data like user scores and rankings can only be written server-side. I also work with React Native, PostgreSQL, and general database design. Outside of security work I'm interested in AI and fintech, and I've co-founded Retez.
