Back to original languageAbout Karim
Freelance fullstack developer with 6 years of experience, specializing in Java, Angular, Spring, and DevOps. I have worked on projects for Airbus, Berger-Levrault, BPCE-IT, and Orange Business Services.
At Berger-Levrault, I contributed to the migration of a GWT application to Angular/Spring, using Angular 16 (RxJs, NgRx) and Spring Security with JWT via Keycloak. I also configured MySQL and MariaDB, and set up CI/CD pipelines with GitLab CI and GitFlow.
During my assignments at Airbus, I worked fullstack with Angular, React, and backend technologies like Java 11 with Quarkus and Spring Boot. I used AWS, Docker, Kubernetes, Jenkins, and performed deployments with ArgoCD. My tasks included configuring Apache and Tomcat servers, setting up SSO with OAuth 2.0 and Keycloak, and optimizing performance with VisualVM and JProfiler.
At BPCE-IT, I developed Java/J2EE solutions with Maven (SpringBoot/Hibernate) and implemented continuous delivery pipelines with Jenkins and XL Deploy. I automated deployments with Ansible and monitored application performance with Kibana, while also providing level 3 support for partners.
At Orange Business Services, I used Robot Framework and Cucumber for test automation, and deployed solutions on Docker containers via Jenkins pipelines, strengthening my skills in CI/CD and automated testing.
My development expertise allows me to support you at all stages of your projects, from design to delivery, while ensuring code quality and adherence to deadlines.
Skills: Java, Angular, Spring, DevOps, Docker, Kubernetes, Git, Jenkins, AWS, CI/CD, Keycloak, MySQL, MariaDB.
