During my summer internship at TAS, I built a full-stack CRM website using Spring Boot and Angular. I focused on backend services, frontend design, and feature integration, contributing to user authentication, data management, and enhancing UI responsiveness. This experience deepened my expertise in full-stack development, particularly in creating reliable interfaces, and reinforced my ability to deliver effective software solutions using the Spring Framework and various tech stacks.

During my summer internship at Esprit, I developed a desktop application and a website dedicated to managing sports clubs, coaches, and users. Utilizing JavaFX and Symfony, I focused on creating a user-friendly interface and implementing robust backend functionality, enhancing the overall user experience and operational efficiency.

During my end-of-study internship at Oliva Software, I successfully implemented a stock and sales management module for the mobile version of the AXELOR ERP.
