En résumé

Entreprises

• Finexkap - Freelance Ruby on Rails

  Paris 2015 - 2015 I assisted the internal development team working on several Ruby on Rails applications by developing new features and reinforcing best practices related to testing and separation of concerns.
  
  Based on my previous experience on REST-full APIs and OAuth 2, I’ve proposed multiple improvements to the Public API scheduled to be released in September 2015.
  
  Most of the time I’ve been working with Ruby On Rails & Angular. The rest of the time I’ve played with Erlang and Go programming languages and learned about Apache Kafka (publish-subscribe messaging bus) and micro services architecture.
