02. About

Portrait of Daniel Keinan

I'm a Computer Science student at Columbia, returning to school after spending two years building production software at Medidata Solutions. I started in tech through App Academy in 2019 and joined Medidata as an Applications Engineer.

Outside of school, I've spent the last few years working as a House Manager at a sober-living community in NYC and as a scout-team practice player for Columbia Women's Basketball. This work has sharpened how I communicate clearly under pressure and enforced my desire to build tools that center on real solutions.

I'm currently looking for summer 2026 software engineering internships.
