About Sylvain

I am a Full Stack Analyst Developer (Web & Mobile) with over 11 years of experience designing and developing modern applications, using a variety of languages and frameworks (including JavaScript, ReactJS, React Native, NodeJS, Firebase, PHP, and more). Passionate about both frontend and backend technologies, I have architected, developed, and worked on complex web solutions as well as mobile applications, including dashboards, booking systems, scheduling and management tools, UI/UX, database migration and aggregation, and various backend services and automation.

Beyond software development, I actively participate in requirements analysis, sprint management, technical planning, and documentation, ensuring the quality and long-term sustainability of projects.

With 11 years of IT experience (and 6 years as a professional photographer), I have collaborated with a wide range of clients and represented companies at numerous trade shows and conferences. Building strong human connections comes naturally to me and, in my view, is essential to the success of any project.

I am currently seeking new challenges, where I can leverage my expertise as an experienced developer.
