Description

Senior Full Stack Java JEE / Angular Developer with 13 years of experience. I specialize in the design and development of distributed and critical systems, particularly in environments subject to high performance and resilience constraints (Payment, Finance, Telco).

Technical and Methodological Expertise

My expertise covers the entire development lifecycle:

Core Back-end: Advanced mastery of Java 17/21, Spring Boot, and Microservices architectures.

Critical Systems/Event-Driven: Essential experience with Event-Driven Architecture (EDA) and Apache Kafka technologies to ensure platform scalability and responsiveness. I have managed synchronous and asynchronous flows for thousands of transactions per second.

Front-end: Proven skills in Angular 19.

DevOps & Quality: Proficient with CI/CD tools (Jenkins, Docker, Gitlab, Sonar), relational and NoSQL databases (MongoDB, Oracle), and the AWS Cloud environment.

Methodology: Regular work in Agile environments (Scrum, SAFe).

Key Experiences and Achievements

I am comfortable taking on large-scale missions, from technical study to production deployment:

Platform Optimization: Contribution to the improvement of offer management and billing platforms (Groupe ADP / Hubone).

Payment/Finance: Evolution and maintenance of critical payment micro-services, requiring maximum optimization of code and event management (PARTECIS).

Mentoring: Experience in mentoring and training new developers, and in ensuring adherence to best practices (code review, SOLID principles).

I am available for missions requiring in-depth technical expertise, strong autonomy, and great rigor.
