Description

🚀 Senior Java Developer – Back-end & robust architectures

With over 10 years of experience, I design and develop robust, scalable, and well-tested backends in demanding environments. A Spring Boot specialist, I master microservices-oriented architectures, messaging (RabbitMQ, Kafka), SQL/NoSQL databases, and Continuous Delivery pipelines.

💡 Proactive, I don't just execute: I participate in technical choices, anticipate needs, and build sustainable solutions.

✅ Strengths

Java Migration (8 → 21), technical refactoring and modernization

Clean architectures (hexagonal, light DDD), thorough testing (unit, integration, end-to-end)

In-depth knowledge of production tools: Git, Docker, Jenkins, Maven…

Responsive, autonomous, and focused on long-term quality

🔍 Notable Project: Smart connected heating

At Datanumia, I worked on the automatic control of electric heating during peak days (consumption reduction).

I developed the entire restoration component

I contributed to the control in all its aspects

Proactive, the current solution relies heavily on my technical choices
