"Andres was an effective and versatile member of our programming team. Andres has the skills and the focus to work on our globally distributed team, doing continuous delivery and pushing his own releases. I like collaborating with Andres. I often pulled him aside on Skype to help me fix or improve something that the other developers had left incomplete. I always felt that we could share ideas and come to an agreement about the next steps. Andres has left his mark on many features in Assembla’s core Rails application. Andres was the original implementer of the @mention feature, which quickly became the most popular and useful feature in our application. He was a major contributor to the Bigplans application, which was built on a different stack with Node.js and Angular. I am sure that he will continue to grow his technical skills and team contributions. "

Andy Singleton, Founder, CEO, Assembla, managed Andres Rafael at Assembla

"I've worked with Andres for more than 5 years. He is a very solid programmer that is willing to take any kind of task. Whenever I had to QA one of his tickets I was never able to find one single bug. One of his great qualities is that he can make decisions on his own so he doesn't need any kind of hand handling when developing features. He also has a great attitude, always willing to help, always creating interesting debates and keeping the morale of the team high. I have no doubt he will be successful wherever he goes and a great, great addition to any team."

"Andres is a great developer, he can solve any problem with ease. I worked with him for years maintaining a top level SaaS application, both in the back-end and front-end and his labour has been exceptional. He is a full-stack developer that can work in any part of an application, and a very cool person to work with !"

"The two most awesome things about Andres were that: (1) as a developer he’s outcome oriented, and (2) he’s a nice person. I would definitely want to work with him again."
