Portugal - Last active: 6 days ago - Tests: 4 - Portfolio: 3

I've worked closely with world-class companies throughout the development of outstanding platforms that have been used by thousands. I'm proficient with PHP and I'm also a Laravel early-adopter - I've been using it since early version 3. I've developed countless applications with Laravel, attended the Laracon conference in Amsterdam and I've written several tutorials that have helped hundreds of other developers. In addition to PHP, I've also used Ruby on Rails extensively to develop complex web applications with full featured test suites. Being a Software Engineering student, you'll be sure to get solutions that are well designed, easy to scale and develop upon. I've taken a CAE (Certificate in Advanced English) by the University of Cambridge and passed with flying colours. Communicating with me won't definitely be an issue. Looking forward to working with you on your next web app!

For the last 12 years I developed sites for Fortune500 companies and technology startups. I've got 20 years of experience in web development, leading teams using agile methodology, scaling web applications with heavy traffic and maintaining big codebases. My best skills are on UI, UX Design and Front-end development but I consider myself a Full-stack developer capable to take on every corner of a project. Today I am building sites with Ruby on rails, Saass, Coffescript, EmberJS and MySQL, with a focus on real time and automated behaviours. I also build IOS and Android apps with Rubymotion. I like Git, write tests and deploy to cloud based enviroments such as Heroku, AWS or dedicated web servers.
