Java Developer


I worked with this research group as a research monitor. I was in charge of understanding the research project needs and find the best technologies to implement a software solution that leads the develop of the research. That was part of my job here. I had to investigate about real-time technologies, such as web sockets, so that I could be able to build a real-time system focused on monitoring a green house. The main idea was to delegate basic and simple tasks to a system and bring behavioral data to a some expert that could be able to understand it.

Java Developer Engineer

I've been doing ruby around 4 years. Started out in small projects and went from there to bigger teams and companies. I consider myself a very passionate ruby programmer. Left the Java world to join a more Open Source oriented community which enables people to go towards a better way of developing software. Love to share and learn things and discuss tech related topics with teammates.

I've been doing Rails for the last 3 years. From API server applications to full-stack apps. I've integrated third parties, done background job processing, performance improvements and API implementation.

Started out building simple jQuery apps and went from the to using more robust frameworks like angular js and ionic. I've been doing angular Js for around 2 years. I've been also exploring other frameworks like EmberJs and ReactJs.

Frozonic - Code freeze management for your repositories

Frozonic

Mobile app version management is particularly important when it comes to security and compatibility. This project was born from the urgency of needing a tool like this. This tool makes it easy for mobile developers to flag app versions so that users will stop using them. Having this sort of control is helpful and useful at some point in the life of a mobile app.
