About

A developer who ships
real things.

I'm a Computer Science student at Brooklyn College, CUNY, based in Brooklyn, NY — passionate about building web applications and solving problems with clean, efficient code.

My background spans both the technical and operational sides of business — from managing a pharmacy team to interning at a startup. This dual experience gives me a unique perspective on building products that actually work in the real world.
