About Ilyass

Senior Full Stack Java / Spring / Angular Developer with over 8 years of experience, I design and develop high-performing, reliable, and scalable applications. Passionate about software architecture and best practices (Clean Architecture, Domain Driven Design, Microservices), I am fully committed to code quality, performance optimization, and the robustness of delivered solutions. Always attentive to technological evolutions, I enjoy exploring new tools and frameworks to continuously improve my work methods.

Specializing in Java back-end, I master the Spring ecosystem (Spring Boot, Spring Data, Spring Security), REST APIs, microservices, and scalability challenges. In parallel, my expertise in Angular allows me to intervene effectively on the front-end and ensure overall consistency of full-stack applications.

I have also held the role of Tech Lead, managing development teams, guiding technical directions, conducting code reviews, and ensuring the proper application of standards. This experience has allowed me to strengthen my skills in communication, coordination, and technical decision-making.

I have worked for clients such as GRDF, Rexel, the Ministry of Justice, La Cipav, Volkswagen Bank, on complex projects requiring rigor, security, and performance. Accustomed to Agile, Scrum, and SAFe environments, I quickly integrate into teams and actively contribute to continuous improvement.

Motivated by technical challenges and collaboration, I am seeking a mission where I can bring my expertise, attention to detail, and ability to drive a project in the right direction.
