About
I am a software developer and Computer Science student at the University of Faisalabad. I like the parts of software people only notice when they break: a download that survives a crash, a login that works in every browser, a vault that never asks you to trust a server.
I build each project end to end, so I also own the database schema, the tests and CI, the installers and the release notes. Every README lists what the project still cannot do.
Since 2021 I have also worked as a freelance designer, delivering branding and pixel art for international clients. Owning each order from brief to delivery, with a 4.8 rating across 222 reviews, taught me to scope work honestly and meet deadlines.
