08 Open Source Initiatives
Beyond individual contributions, I co-founded and lead two open-source organizations creating lasting impact in education and community technology.
Open-Source-Uniandes
Building open technology for the Uniandes community
A student-led initiative at Universidad de los Andes dedicated to creating open-source tools that solve real problems for the university community. We believe the best solutions emerge from collaboration and listening to the people they serve. Every project is built in public — contributions are welcomed, and new ideas are mentored from concept to production.
- Serving 8,000+ students with production-grade open tools
- Student-run, community-first engineering culture
- Open mentorship: from idea to deployed product
- Building a portfolio of impact-driven software
AI-Museum
Democratizing AI education through open, visual, interactive learning
An ambitious initiative to make Artificial Intelligence education accessible to everyone — through open-source materials, rich visualizations, and novel interactive experiences. We are building a comprehensive library of learning resources so that anyone, anywhere, can learn or teach AI without barriers. Our long-term vision is the first physical AI Museum at global scale.
- Open-source learning materials for all levels
- Focus on visualizations, interactivity, and experimentation
- Free forever — for learners and educators worldwide
- Vision: the world's first physical AI Museum
