My future objectives: deepening my skills in native development (Kotlin and Swift) and in Software Craftsmanship.

Tribofilm, Périgny France
2018 - 2020
Until the end of 2018, TRIBOFILM did not use any agile method to organize the work of its teams. I proposed to the management and the development team to implement Scrum in order to energize our group. I therefore underwent training and obtained a Scrum Master certification. I finally took on the role of Scrum Master within a team composed of 4 developers, 1 tester, and 1 Product Owner.
