Ehsanullah Q.
Senior Full-Stack AI SaaS Engineer | AI-Built Apps to Production
Built your app with Lovable, Cursor, Bolt or Replit and now it's breaking, leaking data, or not ready for real users? I fix and harden AI-built Next.js / Supabase apps — auth, Supabase RLS, Stripe webhooks, performance, deployment — and add AI features that work in production. WHAT I DO 1) Vibe-coded app rescue → production Your MVP works in the demo but fails with real users. I audit the AI-generated code, then fix what matters: • Authentication, user roles and Supabase Row-Level Security • Exposed API keys, secrets and database security • Stripe payments and webhooks that actually work • Bugs, slow pages and broken user flows • Clean deployment, monitoring and error handling You get a written audit, a prioritized fix plan, and a stable app you can put paying customers on. 2) AI integration & AI agents for SaaS OpenAI / LLM features inside your product: AI assistants, chatbots over your data, AI agents that take actions through your APIs, and n8n automation — built with cost controls and tested for production, not just a demo. 3) Full-stack SaaS development Next.js and React front ends, Node.js and Python back ends, PostgreSQL / Supabase, Stripe billing, and React Native when you need mobile.
