about
I like problems that start with "we still do this by hand."
I'm a full-stack developer with a backend focus, and most of my work is the same quiet satisfaction: taking something manual and repetitive and turning it into a system that just runs on its own.
Before code, I studied Philosophy and Literature. I don't see it as a detour — it's my edge. It's why I sit with a problem before writing a line, why clean architecture feels like clear thinking, and why I can explain a technical decision to someone who's never opened a terminal. I think of it as digital humanities: building technology that actually means something to the people using it.
