Back to original languageAbout Nathan
Passionate about computer development and with 4 years of experience in work-study programs within two companies, I offer my services to support companies in the design, development, and optimization of their applications.
For 5 years, I have explored multiple technologies through various personal, professional, and academic projects. Among these, the creation of a mobile application (Android and iOS) including a microservices backend (Spring Boot), implementation of security (Spring Security), calls to external APIs, deployment on a server via Docker, and a frontend in Flutter. Teamwork on a connected poker table with card reading (NFC) and an interface for the dealer (React), projects related to artificial intelligence (AI) and Big Data.
