What clients say
Concrete results, satisfied teams. A few words from colleagues and clients.
I worked with Riadh as a developer on the team he was leading. He's the kind of profile any company would want when looking for someone with strong problem-solving ability and a knack for reducing time-to-market. He's talented and always ready to help others thanks to his deep technical knowledge. It was a real pleasure working with him.
I had the chance to work with Riadh, a very professional colleague. He has a genuine sense of commitment to delivering his projects on time for his clients' benefit. His technical expertise in service-oriented architectures, his ability to grow every member of his squad both technically and personally, and how easily he interacts with the teams around him make him a major asset on any project.
I had the privilege of working on the same team as Riadh. He's a passionate, hard-working developer with strong skills who genuinely enjoys sharing knowledge. His team spirit, professionalism and pursuit of excellence are qualities I really valued in him.
It was a pleasure working with Riadh. He's a solid and passionate Java and Kotlin developer for whom quality and doing things right really matter. He's also an excellent speaker who shares his knowledge at tech events (Brown Bag Lunch). If you're looking for a strong senior developer, I highly recommend him.
