Description

I help scale-ups modernize their backend without breaking production.

Specializing in Java/Spring & Platform Engineering, I intervene in commando missions to overcome technical hurdles:

🚀 Critical Expertise: Design of pipelines at 8,000 events/s SYNCHRONOUSLY with strict ordering guarantee via Solace.

🛠️ Modernization: Migration Java 8/11 → 21/25 and Spring Boot 4.

⚙️ Industrialization: Setup GitOps (Argo CD, Kubernetes) and creation of internal artifacts/tools to accelerate your teams.

My approach: precise audit, predictive error vision, and 100% remote execution.

Available for expert missions & short projects (< 3 months).

At Ekino, I worked on the maintenance and evolution of a microservice developed in Spring Reactive, integrated into a microservices architecture for an internal company application.

My main tasks were:

**Maintenance and updates**: Integration of new features, bug fixes, and continuous optimization of the microservice to meet company needs.

**Quality assurance**: Writing and executing unit and integration tests, achieving 90% code coverage, ensuring a robust and reliable solution.

**Collaboration in a distributed architecture**: Participation in the integration and interoperability of the microservice within the company's microservices ecosystem.

This experience allowed me to deepen my skills in Spring Reactive and critical project management while aligning with the high standards of quality and performance of a modern microservices architecture.
