• Kelkoo - Software Architect

  Paris 2008 - 2013 ► Responsible for software architecture of a platform that provides 100M offers to 10M unique visitors/month, 80M API calls /month, in 11 countries.
  
  ► Designed several new subsystems and evolved existing ones to a service-oriented architecture, using separation of concerns as a driver.
  
  Highlights:
  
  ► Developed for several projects, including an automatic price checker of 100K+ offers on external merchants websites, an internal RESTful web service to compute complex urls redirections based on other web services, a webapp to manage architecture information (from logical systems to servers).
  
  ► Rationalized usage of RESTful web services, by introducing Jersey library in replacement of in-house library, standardizing URIs and formats, developing support tools, training all developers (30 devs). Improved time to develop and deploy internal web services by at least a factor of 2.
  
  ► Designed and developed a complete packaging and deploying framework based on maven, RPM, Puppet. This framework replaced Yahoo! tools and helped to increase significantly the frequency of releases. Results presented in french conferences (see below).
  
  ► Evangelized good coding practices, by direct support to developers and organization of more than 30 internal coding dojos (TDD, testing, OO design).
