As part of a development mission at La Banque Postale, I joined a technical team responsible for the design and evolution of critical backend applications in a regulated banking context.

Key contributions:

Development and optimization of Java 17 / Spring Boot microservices with robust and high-performance REST API exposure

Design and optimization of native PostgreSQL SQL queries, particularly for processing large volumes of data via ResultSet

Implementation and improvement of CI/CD pipelines (Git, rebase strategies, continuous delivery workflows)

Integration of application security mechanisms with Keycloak (OAuth2 authentication / authorization)

Service monitoring and observability via Grafana / Prometheus

Adherence to code quality standards with SonarQube, project management via Jira / Confluence

Participation in Agile rituals (sprint planning, code review, daily stand-ups)

At KSR Services, I designed and developed a Full-Stack CRM platform for the automotive sector, from the Java / Spring Boot backend architecture to the Angular interfaces, including real-time data streams with Kafka and AWS S3.

A complete project, from the database to deployment, with particular attention to code quality, performance, and maintainability.

At La Banque Populaire, I designed a Full-Stack application for financial trading floors (Java / Spring Boot + React, deployed on Kubernetes) and managed the migration of a critical Trade flow management API in production, without service interruption.
