    Developer
    September 2025 - Today (9 months)
    La Rochelle, France
    As a freelance developer, I support companies, startups, and individuals in the design, development, and evolution of their web and mobile applications. I work on various projects ranging from high-performance backend architectures to modern frontend interfaces, with a strong emphasis on quality, scalability, and user experience.

    I help my clients turn their ideas into functional products through a solution-oriented approach, attention to detail, and great autonomy.
    My role covers the entire development cycle: needs analysis, technical choices, development, optimization, deployment, and maintenance.

    Examples of interventions:
    - Backend development in Node.js / FastAPI / Django, creation of REST/GraphQL APIs, performance optimization.
    - Creation of modern web interfaces with React and integration of dynamic UI components.
    - Design of mobile applications in React Native.
    - Modernization of legacy architectures and technical migrations (PHP → Python/Node.js).
    - Setting up Docker environments, CI/CD, automation, and DevOps best practices.
    - Integration of external services (Stripe, payment, authentication, OpenAI API, third-party APIs…).
    - Development of internal tools and products to improve processes (automation, AI scripts, dashboards…).

    I undertake both short expertise missions and medium/long-term projects, always with a pragmatic approach: ship fast, measure, iterate.
