SECTION 01 / ABOUT

I like building
things that work.

I got into coding through a love of languages — the idea that you can learn an entirely new way to communicate, and use it to build something real. That curiosity hasn’t gone away. If anything, it’s gotten worse.

I’m a final-year student at KPU, currently building full-stack systems at Surfalytics while finishing my degree. I care about writing code that’s reliable, scalable, and easy to reason about — systems that hold up when real people depend on them.

What keeps me going is the impact side of it. I want to build things that make people’s lives feel lighter — fewer broken flows, less confusion, less overwhelm. I also like being the person who explains things clearly when a teammate is stuck. That part doesn’t feel like extra work to me.

Outside of work and school, I play tennis, follow the markets, and spend time with people who push me to think differently.
