Profesional Profile

I'm a developer based on Medellín, Colombia. Currently I feel pretty comfortable developing in Ruby on Rails, nevertheless I've done a few things using Android and iOS. I'm always trying to write better and friendly code and learning the best practices.

At this moment I'm focused trying to learning more about Data Science and growing my Ruby on Rails knowledge

In the near future I see myself contributing to open source projects, and learning about hardware, IoT and data science.

I also have a Business Management degree which I expect to use somewhere in the future


I normally like to stay informed about many topics (economy, politics, tech), drink a beer on sunny days and spend time with friends and family.

What i can do

My Services.

Back-end development

I'm good creating platforms using Ruby on Rails' restful architecture, whether it is a dashboard or a medium-level complexity app, I can do the job

Front-end development

Let's give some life to those PSD/AI/jpeg/napkins wireframes! I have some knowledge in technologies like jQuery, Sass, Handlebars, Google Charts


A website's experience must be consistent no matter what device is being used. I can help you with that too.

Mobile development

Sometimes is better to go mobile-first, if this is your need, I know a couple of things about iOS and Android

I'm currently available for freelance work.

Feel free to get in touch if you have some idea or project in which we could work together
