Glenn combines over four years of experience as a software developer with an MSc in aerospace engineering. Over the last couple of years, he has worked on a platform meant to monitor global satellite navigation systems, such as GPS and Galileo. He's most comfortable using technologies like Python, JavaScript, React, SQL, and C++, but more importantly, he's always eager to immerse himself in a new technology stack.

Artistic Website
A personal website I made for a painter. It required dynamic additions and modifications to artworks, all managed by a customized back end and a personally styled front end of the web application.

Personal Website
A personal website showing some information about myself and hosting some of the personal side projects I've worked on during the last couple of years.

Whenever I'd like to learn new technology, I also use this website to test some features.

This animated tool provides you with an easy method to see which GNSS satellite had and which ground stations were in view at any moment in time. You can personalize the configuration by selecting the ground stations and GNSS satellites to include in the visualization plots.
