About

Hi, I'm Anas

Portrait of Muhammad Anas Irfan

I'm a full-stack engineer in Lahore, Pakistan. I build backends, web apps and mobile apps, and pick up whatever stack the product needs.

I studied Information Technology at PUCIT, University of the Punjab, and spent two years there as a teaching assistant in labs for programming fundamentals, OOP, data structures, databases and web development. My final-year project used LLMs to recognize human activities from wearable data.

In 2025 I did two internships at the same time, one in Django and one in Next.js, then a month of Rails training at Visnext. From November 2025 I worked at Devntech on long-running Rails codebases, API integrations and Colochousing's move to a new multi-tenant TypeScript platform.
