About Me
Biography
I'm Jon (Sebas) Osorio, a full-stack software engineer with 3+ years building products end to end, from database to backend to frontend. I care as much about how something works as how it feels to use.
Good design solves problems before it looks good. Whether it's a web app, a mobile product, or an internal tool, I bring that same user-first thinking to every build.
