03 — About

Ships whole products, not just tickets.

I'm Zohaib — a full-stack engineer with three production SaaS platforms live right now, including mobile apps on the App Store & Play Store and a marketplace running Stripe Connect payouts.

My strengths sit where most projects get risky: payments & billing (Stripe, wallets, reconciliation), realtime features, and APIs that don't break existing clients. I default to typed contracts, tested code and honest scoping.
