About Ayoub

Senior Engineer with over 10 years of experience in Java/Kotlin Backend development, I have worked on technically complex projects for major clients such as Europcar, SNCF, CNAM, LCL/Crédit Agricole, Safran, and the Ministry of Ecological Transition.

My expertise covers microservices design and development, event-driven architectures with Kafka, REST APIs, security with Keycloak/Red Hat SSO, as well as monitoring and observability (Dynatrace, Grafana, Splunk).

Accustomed to demanding environments (critical systems, high availability, large volumes), I am involved in the entire application lifecycle: technical analysis, development, CI/CD, monitoring, and production support.

Recently certified as a Data Engineer and currently training in AWS, I am expanding my skills towards data engineering and cloud.

Autonomous, rigorous, and proactive, I integrate quickly into Agile teams and support junior profiles in their skill development.
