About Antonio

Senior Software Architect | Insurance & Mutuals Business Expert | DDD & Cloud Native Specialist

With over 25 years of experience in software engineering, I support organizations in designing and modernizing critical information systems.
My expertise has been forged within the Insurance and Mutuals sector (MAAF, MAPA), where I solve complex scalability, compliance (POG/DDA), and automation challenges.

An expert in modern architectures, I favor DDD (Domain-Driven Design) and Hexagonal Architecture approaches to ensure maintainable solutions aligned with your business objectives. Proficient in the entire Java stack (from versions 8 to 25) and the Spring Boot ecosystem (2.x to 4.x), I also lead your transitions to Cloud Native via Kubernetes, Docker, and Kafka.

My areas of intervention:
  • Audit and Architecture : SI redesign, migrating from monolith to microservices.
  • DevOps & Observability : Implementing CI/CD pipelines and monitoring (Prometheus/Grafana).
  • Innovation & R&D : AI integration (AI-102 certification in progress) and high-performance document engines.
Based in Niort, I work as a freelancer to bring technical rigor, strategic vision, and support to your development teams.
