Who I am

Student. Builder.
Curious person.

I'm a first-year CS engineering student with a long-term goal of working at Google or Microsoft. I know I'm at the very beginning — and I think that's actually a good place to start from, because everything I build now is a foundation.

I'm currently learning Python and HTML on FreeCodeCamp, setting up my developer workflow, and pushing my first projects to GitHub. I believe in building things that actually work over collecting certificates that don't.

Outside of code, I'm drawn to things that reward close attention — history, philosophy, furniture design from IKEA's early 90s catalogues, and art I find on cosmos.so. I think good design and good engineering have more in common than people admit.
