  • Product scoping & user-centered wireframes
  • A working MVP delivered in a few weeks

My recommendations.

Very precise and leaving nothing to chance, Adrien's work shows a real willingness to find solutions and solve problems down to the smallest detail, while making an effort to maintain his level of knowledge and expertise at the highest level. Adrien is very attentive to every detail of a project. On top of that, his excellent interpersonal skills make everything easier. A real pleasure.

Marc RODRIGUES

Application Manager

Adrien has worked on several projects within the Postal IS office of the Office des Postes et Télécommunications de la Nouvelle-Calédonie. As a SCRUM Master, I appreciated his versatility and the fact that he always volunteered to help the various team members. He was also very involved in the design of the applications, which were tastefully developed and very much appreciated by the users. On a human level, he integrated very quickly and contributed greatly to the good atmosphere within the team. I highly recommend him.

Sébastien POUILLET

Scrum Master

Adrien joined our development team on two projects combining Angular, SpringBoot and Ionic technologies. Very concerned with the UI and UX aspects of his applications, he knows how to provide effective and relevant design solutions. His affinity for Agile methodology has enabled him to take on the role of Scrum Master on several occasions. A role he fulfilled with unfailing professionalism for part of the project. On the human side, Adrien integrated very easily into the team and played an important role in its cohesion. He's an extrovert who tends to bring team members together.
