About Aurélien

Full-stack IT developer with over 13 years of experience, I design, develop, and maintain business web applications in complex, multi-stakeholder environments.

Proficient across the entire stack, I work on both backend (Java, PHP) and frontend (JavaScript, HTML/CSS, front frameworks), with a solid mastery of relational (PostgreSQL, Oracle, MySQL) and NoSQL databases. I also manage application deployment, server operations, and automation via CI/CD pipelines.

Accustomed to teamwork (Git, inter-team coordination, supervision), interacting with business stakeholders, and managing contractors, I am adaptable to both pure development roles and contexts where IT systems and infrastructure are part of the scope.
