Senior Web Architect and independent consultant with over 20 years of experience delivering software and application architecture projects across diverse environments. I support projects end-to-end, from requirements clarification to technical design and implementation, with a pragmatic, structured and results-oriented approach. My expertise focuses on designing secure, scalable and maintainable business applications aligned with real operational needs. I integrate AI APIs into application architectures to optimise workflows and deliver tangible operational value, while maintaining a strong security-by-design mindset from the earliest stages of system conception. My background combines formal education in computer science, hands-on experience in development and systems engineering, and strong analytical and communication skills developed through complex project environments. I typically intervene on targeted assignments such as: • Senior technical reinforcement • Architecture design and restructuring • Legacy system modernisation • Development of high-value internal business tools I am particularly interested in environments where technology serves clarity, efficiency and long-term sustainability. Additionally, a lifelong commitment to demanding sports practice (team and individual disciplines, coaching, martial arts, endurance sports) has contributed to developing discipline, consistency and the ability to perform sustainably in high-pressure contexts.

For over 10 years, I have been designing and developing my own tools as a full-stack developer, at the core of my freelance activity (CRM, automation, data management). I continuously improve them by integrating new technologies. In this context, I also work in private practice as a therapist, a role in which I also provide training.
Alongside creating the company, I design and develop the entire information system. I implement an internal network and a client management intranet, with workflow automation via APIs (data distribution, retrieval and integration). The website, connected in real time to the database, allows instant updates of listings. The system is built on a PHP / MySQL stack, with JavaScript (jQuery) interfaces and automation scripts. This complete system, designed and maintained in-house, eliminates the need for external IT services. ** Wishing to relocate for family reasons, I sell my company. I take time to reassess my professional direction and confirm my interest in human support. I then train to open my own practice. **
At Steria, I started as a developer on assignments for major clients, notably La Poste. Out of curiosity, I began developing skills in cybersecurity, which led me to work on specific missions in this field. I then evolved into project management, eventually taking on the role of IT project manager. I notably worked for Amadeus, where I was responsible for penetration testing and security between the Sophia Antipolis site and the DMZ located in Germany.
Within this startup, I work with major clients, notably La Poste, and evolve toward full stack development (PHP, SQL, API, JavaScript, client/server architectures, scripting). My algorithmic analysis skills allow me to intervene urgently for Cora during the “ILOVEYOU” virus outbreak, restoring over 600 machines in one night, before official solutions were released. This experience significantly broadens my skillset, both technically and methodologically. ** After several years in consulting, I create my company with the objective of combining human interaction, business dimension and local anchoring. I leverage my IT expertise to design my own CRM, eliminating information system costs. **
Worked as an IT consulting engineer supporting professional clients on hardware and system-related topics, within deployment and support contexts for enterprise IT solutions.
