🎯 Looking for a freelance mission in Fullstack Java / Angular development.
I am Fawez Teka, passionate about web development and new technologies. I am a computer engineer with 4 years of experience in Front-end and Back-end, specializing in Angular and Spring Boot. I have led end-to-end projects with a strong emphasis on microservices architecture (Netflix Eureka) and security (Spring Security, Keycloak). I master SQL and NoSQL databases, and I use tools like Docker, Jenkins, and GitLab CI for continuous integration and deployment.
