01.about_me

I'm Mauricio Barrera, a full-stack software developer, team leader, and project manager based in Montevideo, Uruguay.

I currently work at ICA — Ingenieros Consultores Asociados as a Sr. Full Stack GIS Developer, designing and building custom GIS solutions that integrate Esri ArcGIS technologies (ArcGIS Enterprise, ArcGIS Pro, Maps SDK for JavaScript) with modern frontend and backend development, DevOps practices, and cloud infrastructure — leading cross-functional teams and delivering reliable, scalable systems.

Previously, I worked as a Systems Administrator and IT Support at the Retirement & Pension Service of the Armed Forces (Ministry of Defence), where I managed enterprise infrastructure, servers, and networks. Before that, I was an Administrative Intern at the Transportation Administration Unit of the Montevideo Municipality, and earlier managed the El Faro Club at the Association of Engineering Students of UdelaR for four years.

On the academic side, I hold a degree-level background in Computer Engineering from the Faculty of Engineering – Universidad de la República, and I am completing a Bachelor's degree in Business Administration at the same university. I also hold a Technological Bachelor in Computer Science from Pinar Educational Institute.

I speak fluent English (Cambridge C2 — CAE Grade A) and native Spanish, enabling me to work effectively in international and multilingual environments.

Together, these experiences let me bridge technology and business — delivering solutions that are both technically robust and aligned with strategic objectives.
