About Rabert

🚀 Java / Fullstack Tech Lead & Expert Craftsmanship (24 years of experience)
Java expert since 2002, I support technical departments in modernizing their IT systems. My approach combines architectural vision, DevOps excellence, and leadership to transform complexity into scalable solutions.

🛠️ Expertise & Scope of Intervention
Modernization: Refactoring and migration from legacy systems to microservices architectures.

Innovation: Design and development of high-performance "from scratch" projects.

Business Strategy: Technical alignment through DDD (Domain-Driven Design) architecture.

đź’ˇ Key Achievements

Société Générale (Tech Lead): Leading a "from scratch" project using Spring Boot with a DDD architecture.

Vinci Energies: Microservices architecture, REST APIs, and CI/CD industrialization (5 years of dedicated DevOps experience).

⚙️ Quality Culture & Operational Excellence
Convinced that software quality is the major lever for performance, I impart best practices to teams:

Engineering: TDD, BDD (Cucumber), Clean Code, Code Review, Mentoring.

Industrialization: CI/CD (Jenkins, Git Flow, Pipelines), Sonar, Code Coverage.

Observability: Proactive monitoring and production tracking (Kibana, Prometheus).

Collaboration: Agility, knowledge sharing via Jira/Confluence.

My mission: to transform technical complexity into fluid, maintainable, and value-creating solutions for your business.
