Back to original languageAbout Cheikh
Application architect and FullStack Java/JS developer with over 8 years of experience, I am committed to providing innovative, robust, and rigorously tested IT solutions. Specialized in Java (7 to 21) and JavaScript (Angular, React) technologies, I support companies in the design, implementation, and optimization of their systems while ensuring security, performance, and scalability.
As an advocate of Test-Driven Development (TDD), I ensure that my solutions are functional, maintainable, and tested from the start. My experience in SOLID and good development practices is supported by the use of testing frameworks such as JUnit, Mockito, and TestContainers for Java.
I have worked with major accounts such as Groupe CCF, Orange Business Services, and Tissot, where I led teams on continuous integration, API security (OAuth2), the implementation of automated testing pipelines, and systematic code review processes. My quality-oriented approach ensures that each solution meets business needs while being scalable.
My expertise in agile methodologies (Scrum, Kanban), coupled with my mastery of DevOps tools such as Kubernetes, Docker, Gitlab CI, and SonarQube, allows me to deliver reliable and scalable solutions while optimizing deployment processes and minimizing risks.
Technical skills:
Languages: Java 8, java 11, java 17 java 21 , TypeScript, HTML5, CSS, C#
Frameworks: Spring Boot, Hibernate, Spring Data, Spring Security, Angular, React, Node.js, Vue.js
Cloud: AWS (S3, EC2), Azure (Entra ID, Functions), DigitalOcean
Tests: TDD, JUnit, Mockito, TestContainers
DevOps: Kubernetes, Docker, GitLab CI, SonarQube
Methodologies: Agile (Scrum, Kanban), SOLID
Always looking for new challenges, I am available for ambitious and innovative projects.
