About

CS student at Columbia and 2x SWE intern at Comerica — building scalable backend services and thoughtful applications across web and mobile.

I'm Ismael Olivarez, a CS student at Columbia University and current SWE intern at Comerica Bank. I build scalable backend services and thoughtful applications across mobile and web, with experience spanning Spring Boot, React / React Native, and AWS.

Previously, I shipped projects like Timeline (a customizable social app) and Plant Resilient (a geospatial plant-compatibility tool) — the kind of systems work that has to hold up under real traffic.
