Team

Mo + Us = Mouse

Mohsin plus Usama equals Mouse.

Mohsin

Co-founder & CEO

The friendly voice behind every “let's do this.” He finds the people, wins their trust, and steers Mouse Stack so every project feels like a partnership.

New city, new country, same energy. The phone never stopped ringing.

Usama

Co-founder & Lead Developer

Give him an empty repo and a wild idea, and he'll hand you back a product. Eight years of turning “can we even build that?” into “it's live.”

Swears his superpower is wasting time. Somehow, things keep shipping.

Batch-mates at PUCIT, University of the Punjab, 2013–2017.
