Description

Java Spring Boot Developer, I mainly work on existing business applications: feature evolution, performance optimization, stabilization, and technical support.

I particularly appreciate projects where it's necessary to quickly understand an existing system, identify blocking points, and implement simple, robust, and maintainable solutions.

I intervene in particular on:

• Spring Boot backends and REST APIs development

• Taking over and modernizing existing applications

• Performance optimization and complex problem-solving

• PostgreSQL database design

• Integration of systems and third-party services

• Kafka and distributed architectures

• Angular business interfaces

• Deployment, CI/CD, and maintenance

Throughout my experiences, I have worked on applications used in production by many users, notably at Air France and URSSAF, with challenges related to reliability, performance, and maintainability.

Thanks to my full-stack profile, I can also work on Angular interfaces when a global product vision is necessary.

I also hold the CKAD (Certified Kubernetes Application Developer) certification, which allows me to work on containerization, deployment, and application operation issues on Kubernetes.

Available for backend reinforcement missions, technical expertise, audits, or application modernization.
