Freelancer profile translated to English.

Description

Do you need to evolve a business application, industrialize your deployments, or bring order back to an architecture that has become difficult to maintain?

Fullstack Developer and DevOps expert with over 15 years of experience, I support companies on complex web projects: API design, SaaS applications, software architecture, CI/CD pipelines, Dockerization, and optimization of development and production infrastructures.

My added value: a transverse vision capable of connecting business needs, code quality, team performance, and deployment reliability. I regularly work on refactoring, technical debt, industrialization, and technical support for developers.

Main Stack: Ruby on Rails, PHP/Symfony, Nuxt.js/Vue.js, Docker, Linux, CI/CD, DevOps automation, and application architecture.

Open to freelance missions with a strong technical dimension as well as permanent opportunities in lead developer, software architecture, or tech lead roles.
