About

I work on banking platforms that serve millions of users daily — building secure transaction flows, design systems, and back-office tools across both traditional online banking and digital banking. My focus is on writing software that's reliable and performant when it matters most.

I am actively seeking new opportunities to grow, learn, and contribute my expertise.

In my free time, I play Dota 2—mostly Meepo, because it helps me with my state management nightmares.

Outside of client work, I run my own infrastructure— two self-managed servers, a monitoring stack, and a handful of internal tools that let me move faster. This site is hosted on them.
