Full stack, not one layer

Full-stack and mobile engineer in Okara, Pakistan. Freelancing since 2020. Remote with US teams since 2023.

I write React and Next.js UIs, Node and Python APIs, PHP Laravel Web Applications, and React Native or native iOS when the job is mobile. I also own deploy: Docker, Kubernetes, CI/CD, and keeping production quiet. Same stack for web products, mobile apps, SaaS, voice-AI calling tools, payments, bank linking, and the infra under them.

Published own 8+ Apps on Play Store and App Store.

Outside work I help run CLEP, a student nonprofit that funds children's education in Pakistan. I also reported a TOTP replay bug in OpenAI's 2FA through Bugcrowd.

He reviews the existing codebase before building, flags edge cases and scope questions before writing a line, and communicates with real clarity. When something needed troubleshooting, he diagnosed it precisely and gave me exact, step-by-step instructions that worked the first time. I'm a non-developer, and he never made that a problem.

I'm now placing my third order back-to-back, and that alone says everything. What truly sets him apart is that he builds my projects like they're his own — that level of ownership, care, and pride is rare, and it shows in every single delivery.
