Available to hire
I’m Chaouachi Hamed, a Java/J2EE fullstack engineer with hands-on experience building microservices-based platforms using Java 17, Spring Boot, Hibernate/JPA, and Kafka. I enjoy designing reliable backend services, creating clean persistence layers, and ensuring maintainable, testable code through solid engineering practices.
On the frontend, I build responsive user interfaces with Angular 16/AngularJS (micro front-end/Spa approaches) and integrate them with REST APIs. I’ve worked in Agile/Scrum environments and in production-focused setups, troubleshooting across DEV/PPRD/PRD, using modern tooling like Git, Maven, Jenkins, Sonar, Docker, and cloud technologies to deliver stable features end to end.
