What I'm looking for

I am seeking a senior engineering role where I can lead backend architecture and cloud-native delivery, mentor teams, and build resilient, well-tested systems in finance or enterprise domains.

I am a seasoned Java tech lead with over eight years of experience designing and implementing backend systems, integrations, and microservices for financial and enterprise clients.

I have led technical architecture and development on Merchant Manager at Pluxee (Sodexo), built transaction-processing flows for London Clearing House, and managed EAI integrations at Société Générale, consistently focusing on reliability and scalability.

My hands-on stack includes Java (8–17), Spring Boot, Spring Integration, Kafka, Docker, Kubernetes (AKS), Azure DevOps, relational databases (Oracle, Postgres, DB2), and front-end frameworks such as Angular.

I prioritize test-driven development, clean architecture (hexagonal, CQRS), automation, and coaching teams to deliver robust production systems across high-regulation finance and large enterprise environments.
