Background

A bit More About Me

I grew up in a small village in Sindh, Pakistan, where my curiosity about computers eventually led me to study Computer Science and build a career in software engineering.

Today I work with international teams building Web3, blockchain, and financial products while continuously exploring new technologies and product ideas.

Outside engineering, I enjoy fitness, learning about emerging technologies.
