I Develop Smart & Usable Web Apps

Testimonials

Carlos is a passionate Rubyist and a pleasure to work with. He knows Ruby and Rails inside-out and always keeps up with current best practices and available libraries. He writes elegant, easy-to-maintain code with excellent test coverage. He's an asset for all levels of product design: user experience, system architecture, test frameworks and code design. He works well remotely and as part of a team and is willing to put in long hours to deliver quality results under pressure. One of the best developers I've worked with; I still refer back to his designs from time to time.

Christopher Cunningham
CTO at GlossGenius, formerly Lyft, Soundcloud & Huge — Miami, Florida

Carlos is an enthusiastic, bright and extremely capable developer and team member. In addition to writing great code, Carlos always keeps his ear to the ground about new technologies, marketplace changes and opportunities for the company to evolve and shine, bringing significant added value to his workplace.

Gabe Zichermann
Highly Technical Product, Marketing and Leadership Executive with Startup, Ecosystem and Growth Experience — Los Angeles, California

Eloquent in Ruby and armed with a methodological approach to software development, Carlos' ability to provide simple and elegant solutions to complex problems made him a valuable member of the web development team.

Norbert Brunner
Director of Digital Technology — Gibraltar

Carlos is a top-notch developer with a solid knowledge on Ruby, Rails and different frontend technologies, and a great addition to any team. He is detailed and perfectionist, always writing high quality code at a speed of light pace. His greatest skill, though, is that he will increase the team level significantly by spreading his deep knowledge to his peers, and will do that while constantly delivering new functionality.

Antonio Santos Velasco
Site Reliability Engineer at GitHub — San Francisco, California

I've hired a number of Rails developers to work on my social gaming app over the years. As far as I'm concerned, Carlos is one of the Rails Community's top full-stack developers. He possesses a deep understanding of the Rails framework that has enabled our team to build a more flexible, maintainable app (from the front-end to the back-end). He's fully up-to-date on the latest Rails practices and gems, and effectively communicates how these new developments can improve development productivity. I couldn't imagine undertaking another Rails project without Carlos' involvement.

Chris Cairns
Founder & CEO of Skylight, Digital Services Coalition Co-Founder, 18F Co-Founder, Presidential Innovation Fellow — Sarasota, Florida

Carlos is a Ruby on Rails guru. There are few that know or keep on top of the internals with such dedication, and he is considered the go-to man when you can't wrap your head around something framework related. Carlos takes great pride in his work, and his code quality and advocacy of DRY principles throughout makes for very happy peers! He continually took on mammoth refactoring tasks which would make most developers cringe, and consistently furthered the quality of the Victor Chandler codebase for the better. I miss not having Carlos around when I get stumped with Rails - a two minute conversation with him often saves an hour or more in research.

Matt Williams
Software Shepherd — Lithuania

Carlos is one of the best developers I know. A key asset to any team, he is a dedicated developer who can be trusted to take complex projects from beginning to end with great professionalism and reliability.

Developer at Ethereum Project — Montreal, Quebec

Carlos was an excellent programmer to work with, and I gained some great insight from him. He has a great knowledge of Ruby and programming in general has a good attitude; I recommend him as a first choice for your next project.

Trabajar con Carlos da la seguridad de que el proyecto que tienes entre manos va a salir bien. Es muy buen front, pero también se maneja muy bien en back, en apps para Facebook, iPhone y sabe comentar con criterio aspectos relacionados con diseño. Estoy muy contento con su trabajo. Volvería a trabajar con él en cualquier cosa que implique desarrollo.
