01 / About

A systems thinker.
Always learning.

Usama Razzaq · Lahore, Pakistan

Software engineering, with people and products in mind.

Comfortable refactoring deep, complex legacy codebases (PHP, Laravel, MySQL) and building secure greenfield systems using modern stacks (Next.js, NestJS).

Beyond product work, I mentor developers and read foundational engineering and behavioral literature to write cleaner, more maintainable code and think more carefully about systems.
