Aside from being a developer, I expend my free time hanging out with cool people, drinking beer, chilling, working out, travelling and cooking. I am quite familiar travelling within Colombia, and I've also been in Brazil, the United States, Mexico and Uruguay.

I always wanted to be a tech entrepreneur and an open source contributor so I am looking forward to show you many more interesting projects.

Projects & Open Source Collaborations

Java / Android WebSocket Client

I developed a WebSocket client for Java / Android as defined in RFC 6455. The goal of this project is to provide a very lightweight WebSocket client for Java, with low overhead and high performance.


This is the Go language driver for RethinkDB and I have fixed some bugs.

Voiding Diary

I developed an Android Voiding Diary for urology patients. Patients will be able to record their daily liquid intakes, voids and leaks of urine, and send a detailed report to their doctors.
