I build and secure web apps for small businesses — from booking systems to AI-powered support tools.
I recently took a café queue/reservation app from a rough starting codebase to a live, security-audited production deployment (React, TypeScript, Supabase/Postgres, Netlify). Along the way I found and fixed a client-side price-tampering exploit, a double-booking bug, and a self-service role-escalation vulnerability — all patched at the database level so they can’t be bypassed from the frontend.
I also build AI chat widgets that answer customer FAQs (hours, menu, location) without hallucinating — grounded strictly in the business’s own info, so answers stay accurate.
Live examples:
Stack: React, TypeScript, Vite, Supabase/Postgres, Netlify, Gemini API
Based in Penang, working remote/async — happy to scope small fixed-price projects or ongoing work.
We will review the reports from both freelancer and employer to give the best decision. It will take 3-5 business days for reviewing after receiving two reports.
