Guillermo Barreto — Python backends and full-stack apps

Python backends. Full-stack apps. Building toward an SDE role.

IT support at Amazon · Software Engineering at WGU · Chicago

I work in IT support at Amazon and study Software Engineering at WGU. I'm based in Chicago and working toward an SDE role, mostly focused on Python backends and full-stack apps.

Most of my projects use Python, FastAPI, React, and TypeScript. Lately, I've also been looking for open-source projects where I can contribute fixes and tests.

A few things I've been building

🛰️ AstraScope — A satellite tracker with an interactive 3D globe. It brings together orbital data, pass predictions, and a FastAPI backend that caches data when providers are unavailable.

🔗 Shortly — A URL shortener with accounts, custom links, and click analytics. The backend uses PostgreSQL for storage and Redis for faster redirects, with tests and Docker setup in the repo.
