Jesus A. Montelongo — Software & Systems Engineer

01 · About

A generalist who ships, from the keyboard to the cable tray.

I like problems that span the whole stack — including the literal stack in the IDF closet.

I'm a Computer Science student at UTEP (May '27) and a practicing engineer at Polibius Tech, where I design IT infrastructure for small and medium businesses while also building the internal tools and web platforms that keep operations moving.

On the software side, I work full-stack — React / React Native on the front, Spring Boot, Express, and Django on the back, with PostgreSQL and MongoDB underneath. On the infrastructure side, I've racked switches, terminated patch panels, and brought up networks for clients including Amazon, ADP, GECU, McDonald's, and Gold's Gym.

I'm equally comfortable in a Figma file and in an MDF — and I think being good at both makes me better at either.
