About Kevin

A Ruby developer for over 10 years, I have had the opportunity to work with companies of all sizes and on projects of all kinds (e-commerce, transport, institutional sites, web hosting...).

My affinities are mainly with back-end development, but I am able to intervene on a good number of front-end, availability, architecture, security/compliance issues... All with a strong emphasis on improving internal tools, processes/methodologies used, and on communicating clearly, intelligently, and permanently.

I pay great attention to maintainable development, testing and good practices.
