Back to original languageAbout Jerome
Full stack developer with 20 years of experience in designing and developing complex backend systems. I primarily work with Java Spring Boot architectures using a DDD/CQRS approach, robust REST APIs, and React interfaces.
My playground: demanding business domains — scheduling, e-commerce, customer service, flow management — where domain modeling truly makes a difference.
What I bring concretely:
- Design of event-driven architectures (CQRS, Outbox Pattern, Event Sourcing)
- Production-ready Spring Boot APIs with optimized PostgreSQL and JPA
- Maintainable React interfaces, focused on DX and performance
- Full autonomy, no need for constant guidance
I integrate AI tools into my development workflow — particularly Claude Code for accelerated delivery: code generation, architecture review, automation of repetitive tasks. Result: a quality/speed ratio significantly above classic development.
Available remotely for freelance missions. I work on both greenfield projects and legacy system modernization.
