Gilles is a passionate engineer who loves technology, science and problem-solving. He has a scientific background and defended a PhD in Physics in the domain of optoelectronics applied to telecommunications. He then started a business in this field and built an SAAS CAD tool which can design, simulate and produce microelectronic and optoelectronic systems. Complexity was high due to the infrastructure required to perform multi-physics simulations in the cloud and to create advanced GUI in a browser allowing users to manipulate thousands of geometrical shapes without lags. After this fantastic experience, he fully embraced a software development career and joined Fastbooking in the core team. He finally joined Kapten (formerly known as Chauffeur Privé) as a squad leader at the end of 2015 and helped the company on many different projects in order to offer the best user experience to their customers, to make the platform fully scalable and resilient.
