Portrait of Guillermo Barreto

Guillermo Barreto · Amazon IT · Software Engineering @ WGU

Learning to build software, one project at a time.

I work in IT at Amazon and study Software Engineering at WGU. Outside of work, I build full-stack and backend projects to strengthen my skills in APIs, cloud systems, testing, and software design.

01 / Selected projects

Projects built by following my curiosity.

I use each project to explore a specific problem, practice technical decisions, and understand how the pieces fit together.

Active Project

AstraScope

An interactive satellite and near-Earth monitoring project I use to explore data visualization, APIs, orbital data, and full-stack development.

  • SGP4/SDP4 orbital propagation
  • Observer-based pass predictions
  • Cached public-data APIs
  • Frontend and backend tests

02 / Experience & education

From supporting systems to learning how to build them.

Amazon IT gives me hands-on experience with troubleshooting, reliability, users, and real operational pressure. WGU and my projects are helping me turn those lessons into software engineering skills.
