Description

Java & DevOps Expert – Microservices & SRE Architect

14 years of experience dedicated to technical performance and innovation

Passionate about technical challenges and operational excellence, I am a Full Stack/Back-end Java and DevOps expert, specializing in microservices architecture, continuous integration (CI/CD), and performance optimization (SRE). My background, marked by critical missions at Enedis, Fiducial, and Atos/RTE, has allowed me to develop in-depth expertise in run management, L3 diagnostics, and proactive monitoring, while ensuring trusted client relationships.

What I bring to your projects:

✅ Technical Expertise: Mastery of Java (8-21) ecosystems, Spring, Kubernetes, Kafka, Docker, and databases (Oracle, PostgreSQL, MongoDB).

✅ DevOps & SRE Vision: Industrialization of processes, advanced monitoring (AppDynamics), and complex incident resolution to ensure the stability and performance of your applications.

✅ Technical Leadership: Team support, L2 training, and continuous improvement project management (code optimization, load testing, cyber).

✅ Pragmatic Approach: Design of robust solutions (e.g., extracting 142,000 Oracle lines to Kafka in <1s), and development of innovative POCs.

My dual profile as a seasoned developer and technical referent allows me to combine technical rigor, analytical thinking, and a service-oriented mindset. Whether it's modernizing your IS, optimizing your workflows, or strengthening your application resilience, I am committed to delivering concrete results aligned with your business objectives.

Available to discuss your needs in architecture, DevOps, or application performance.
