Back to original languageAbout Zakaria
Full-stack developer with strong backend expertise in Java (Spring Boot), I assist companies in the design and development of robust, scalable, and performance-oriented applications.
I primarily focus on creating REST APIs, implementing microservices architectures, and integrating complex systems. I pay particular attention to code quality (Clean Architecture, SOLID principles) as well as application maintainability and scalability.
During my experiences, I have worked on projects with high business value, including:
development of backends in Java Spring Boot and .NET
design of distributed architectures
integration of external APIs (REST, GraphQL)
implementation of CI/CD pipelines and Docker/Kubernetes environments
On the frontend side, I also work with Angular to develop modern and high-performance interfaces.
My goal: to deliver reliable, maintainable solutions adapted to your business challenges, while ensuring optimal performance.
