Real Systems, Real Problems

Software I've built beyond classroom exercises.

My strongest work is focused on business applications, operational workflows and backend systems that solve practical problems.

About Me

I like building software that actually gets used.

I'm a Business Informatics student at Universidad de Costa Rica, focused on backend development, enterprise applications and cloud technologies.

My work combines software engineering with business process thinking. I'm interested in systems that help companies manage operations, automate workflows and make better use of their data.

Right now, I'm strengthening my portfolio through real projects, cloud deployment experience and production-oriented development practices.
