About Gael

With over 16 years of experience in information systems, I now offer my skills as a freelancer to support large corporations, SMEs, and small businesses in their IT projects.

Throughout my career, I have worked in demanding and varied environments, both civilian and military, in France and internationally. My experiences as a Network Architect at Optimum Informatique in Montreal and previously as a Network Engineer / Solution Architect at Capgemini have allowed me to develop solid expertise in SI architecture design, complex project management, and client support, from pre-sales to production.

I specialize in the design of secure network architectures, the supervision of multi-site infrastructures, and the resolution of critical issues related to the evolution of information systems. My career has enabled me to develop a strong adaptability, a committed sense of service, and a high degree of autonomy in managing assignments.

Today, I have chosen entrepreneurship to prioritize autonomy, proximity to my clients, and the quality of services delivered.

📍 Based in Montreal, with a secondary residence in Colombes (92), I am available for remote assignments or on-site in the Paris region, as well as in the Toulouse and Bordeaux regions.

Open to opportunities and new collaborations.
