About
Engineer first. Builder always.
I'm a Software Engineer with 5+ years of experience at BRB Bank and an independent product builder. I think in systems, build with purpose, and ship things that work.
My focus sits at the intersection of backend engineering and product thinking. I don't just write code — I think about what should exist, why it should exist, and how to build it well.
