Description

I design and deliver scalable web applications in Java/Spring Boot (REST APIs) and React/Angular.

From use case design to production, I apply DDD and hexagonal architecture, industrialize via CI/CD and solid testing to accelerate delivery without sacrificing quality.

What I do:

- Java/Spring Boot REST APIs: contract-first (OpenAPI), validation, versioning, idempotency, pagination, security (Keycloak).

- React/Angular/TypeScript Front-end: performant interfaces, complex forms, state management (React Query), accessibility, Cypress tests.

Quality & Delivery: JUnit, Jenkins, OpenShift, code reviews and checklists, observability, useful documentation.

Domains: insurance, logistics, public sector, medtech/AI.

References: MAIF, FedEx, Belgian Government, Amplitude Laser.

GitHub: Contact: available for freelance (remote/France/Belgium).
