• Architect & Backend Developer Freelance

  Squad Twelve
  Jan 2017 - aujourd'hui

  I’m a software engineer and freelancer, and I used to train by myself on many
  technologies. For 12 years, I got interested in development, software and system
  architecture, and agile methodologies. I’m challenged on systems that require to be
  impactful and to scale rapidly so for the last few years, I specialized myself in backend
  development at scale. My main language is Java but I used other languages for my
  projects like Python, Javascript or Golang.
  My ideal team to work with is a team where code quality and continuous integration is a
  must. The team shall be able to manage itself, to know how to work with remote people
  and to enable people to share between each other.
  On the business side, I’m interested in disruptive innovations that can create a big social
  or economical impact. I perform product development through the Lean Startup
  methodology. I’m also experienced in Agile processes on several sites: internal teams, offshore teams and customer teams.

  methodology and used Design Thinking tools.
