Qasim Hassan

About

I'm a Senior Full-Stack Engineer based in Lahore, Pakistan, with 6+ years building mobile and web products end to end — architecture, frontend, backend, payments, and increasingly, AI integrations. Most of that time has been spent owning products completely rather than working on isolated pieces of someone else's system.

My core stack is React Native and Next.js on the frontend, with Node.js, FastAPI, and PostgreSQL on the backend. Over the last two years that's expanded into applied AI — integrating the OpenAI and Claude APIs into production products, and working with computer vision models like YOLO11, SAM2, and DINOv2 on real-time pipelines.

I've worked across both freelance and long-term engagements: 100% Job Success on Upwork as a Top Rated Plus freelancer, an 18-month international client engagement on the Qubio ecosystem, and full-time work at StarComputer Labs where I lead architecture across mobile, web, payments, and AI. Alongside client work, I run Jafrix System, my own studio, where I've built and published Innerverse and am currently developing Dealflow AI and Decidr.

I hold a B.Sc. in Computer Science from COMSATS University, Lahore. Right now I'm working through a structured AI curriculum (Level 1–5) while shipping updates to Innerverse.
