Description

Senior Java Developer and Analyst Developer with over 14 years of professional experience in the software industry, I support companies and public institutions in the design, architecture, and deployment of highly scalable critical applications.

My software expertise primarily revolves around the Java / Spring Boot ecosystem and microservices architectures, with rigorous mastery of data persistence under PostgreSQL. Passionate about DevOps culture and automation, I also work on Cloud infrastructure, particularly for setting up secure and scalable environments on AWS using Terraform.

Having collaborated within large organizations, notably for provincial ministries in Quebec, I combine solid technical rigor with excellent business needs analysis skills. Whether it's designing an end-to-end microservices architecture, integrating secure payment gateways (Stripe), or automating infrastructure deployments, I am committed to delivering clean, efficient, and sustainable code.

Available for strategic backend or cloud architecture mandates.
