I Develop Smart & Usable Web Apps

About Carlos Paramio

I'm an expert in web applications development and architecture with more than 10 years of experience. During my freelancing time, I've helped to enterprises and startups all around the globe to design and build their projects, spoke at many conferences and workshops about development technologies and processes, and collaborated with the best in the industry to offer the clients an excellent and quick service.


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.

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
Digital Development Manager at Betvictor, 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.
