A chatbot wired to my résumé — it answers questions about my work, skills, and availability. Off-topic questions get answered too, reluctantly.
What I do.
SaaS, APIs & AI — from Pakistan.
From database schema to deployed UI — one developer owning the whole slice, so nothing gets lost between handoffs.
SaaS platforms
End-to-end product builds — auth, billing, dashboards, and multi-role systems shipped production-ready.
Secure APIs & backend
Hardened Node.js and FastAPI services — OWASP-informed auth, rate limiting, and zero-trust by default.
AI & LLM integration
Chatbots, RAG pipelines, and automation wired into real products — not demos that die in a notebook.
Performance & scale
Redis caching, query optimization, and deploy pipelines that keep p99 low as traffic climbs.
Clear process.
No surprises.
Four steps, fixed price, written scope. You always know what happens next — and what it costs.

Securing data.
I am a Full-stack developer specializing in React, TypeScript, and Node.js. I design and ship production SaaS platforms end-to-end — from database schema to deployed UI.
Today, I am the founder and lead developer of BugChase — a live, multi-role marketplace connecting companies with security researchers. I architected the platform around a five-service core that powers bug bounty and vulnerability disclosure programs at scale.
My rule is simple: secure by default, measured in production, and documented enough that any engineer can pick up where I left off.
