I'm Zannatun Sheum — Founder of Validate.QA, Sr Software Engineer, Traveler, Hiker, Athlete. I founded Validate.QA and work as a senior software engineer (currently at Sandata Technologies). With 11+ years of professional experience across software quality and product engineering, I design systems that are fast, thoughtful, and dependable.

How I work
A few things I believe.
Ship with craft
Quality over quantity. If it goes out with my name on it, it gets the details right.
Stay a beginner
The moment I stop learning is the moment I stop growing. I try to say yes to hard things.
People first
Tech is a tool. People and experiences are the point. I build with empathy in mind.
Do the reps
Consistency beats intensity — in code, in training, and in life.

A product to build, a problem to untangle, or a coffee chat.
