About Jeoffray

Fullstack Java Developer with over 6 years of professional experience in high-traffic web applications and complex information systems.

I primarily work on Java / Spring Boot projects with a strong backend focus:

  • REST APIs,
  • application architecture,
  • security,
  • automation,
  • software quality,
  • CI/CD,
  • business workflows,
  • and process industrialization.

I am currently working on several strategic projects in the public and university sectors, focusing on:

  • governmental platforms,
  • authentication and SSO,
  • application workflows,
  • centralized APIs,
  • data processing automation,
  • and high-volume business tools.

My main stack:
Java 11/21, Spring Boot, Angular, PostgreSQL, Keycloak, Docker, Jenkins, Terraform, Ansible, Python.

I am also very interested in the uses of AI in software development:

  • automation,
  • development assistants,
  • content generation,
  • workflow optimization,
  • and integration of AI tools into business processes.

In parallel to my assignments, I also develop several personal web projects related to website editing, automation, and technical SEO.
I notably use React, Astro, and WordPress to design, maintain, and industrialize a network of content-heavy websites.

Recognized for my autonomy, adaptability, and code quality, I quickly integrate into demanding technical teams and complex environments.
