After starting my career as a junior Java developer, I now have several years of experience as an application architect with an expertise with Java and scala language. I had the opportunity to work for several companies operating in different fields of expertise (finance, transport, booking, ticketing), and on several types of projects (from small scale projects, 1 developer during few months, to very large ones, 150 people during 4 years) where I acted as either a developer, a technical team leader or an architect.
