Freelancer profile translated to English.
Back to original languageAbout Hichem
I am a Full Stack Java Development Engineer, with solid expertise in Core Java, as well as the main components of the Spring framework (Core, Boot, Data, Security) and Hibernate/JPA.
I am involved in the entire application lifecycle: technical design, development, testing, deployment, continuous integration, and production release.
Thanks to my experience on several projects in different business sectors (banking, public sector, digital platforms), I have developed a strong adaptability and mastery of modern architectures oriented towards microservices and REST APIs.
On the front-end side, I also have expertise in Angular and Vue.js, which allows me to operate as a true Full Stack profile, capable of designing and developing complete, high-performance, and maintainable solutions.
Rigorous and quality-oriented, I apply good development practices: Clean Code, SOLID, TDD, CI/CD, and Agile methodologies (Scrum / SAFe).
