Founder · PC Nexus
The mind behind PC Nexus.
I'm building a career at the intersection of data and software. Day-to-day that means writing Python and SQL, sketching pipelines, exploring datasets, and shipping interfaces that make the work usable.
My approach is simple: pick a real problem, build it end-to-end, document it, repeat. Every project on this page exists because I wanted to understand something better.
