About Moujib

Senior Full Stack Developer with over 8 years of experience in designing and developing business applications.

I support my clients throughout the entire development cycle: needs analysis, technical design, development, testing, deployment, and maintenance.

Specializing in Java, Spring Boot, Kafka, PostgreSQL, and React, I work on modern architectures (microservices, REST APIs, hexagonal architecture, event-driven).

During my assignments, particularly in the banking and insurance sectors, I participated in the design of critical platforms with high requirements for quality, performance, and security.

I can be involved in development topics as well as architecture issues, code reviews, performance optimization, or team support.

Main technologies: Java 17/21, Spring Boot, Kafka, PostgreSQL, React, Docker, Kubernetes, GitLab CI/CD, Jenkins, AWS.
