Back to original languageAbout Martin
Senior Flutter / Full Stack developer with a strong product and quality mindset, I am currently working at Leroy Merlin on the development and maintenance of Flutter mobile applications connected to a Java backend. I apply Clean Architecture principles and agile best practices in contexts with high business stakes and at scale, particularly on white-label applications.
Graduated from EPITECH, I have acquired solid experience in Flutter, Java, Kotlin, and TypeScript, contributing to various projects ranging from security to cross-platform business solutions (iOS, Android, Web). Curious, involved, and collaboration-oriented, I enjoy building robust, performant, and useful solutions with teams, paying close attention to user experience and code maintainability.
