Profile

I’m a Software Engineer from Argentina with more than 12 years working with RoR on webs projects.

Using the whole stack of tools that RoR offers, I've created from small websites to enterprise applications. I consider myself a backend developer but I also have quite experience with frontend stuff.

I have lead many projects following Kanban with distributed teams so I’m used to work with Agile Methodologies.
