About Olivier

With over 30 years of IT experience, I have built solid expertise at the crossroads of development, infrastructure, and digital transformation.

I have worked in complex environments, notably at ENGIE, where I held roles as a lead developer and technical leader. There, I managed teams, coordinated development efforts, and contributed to the implementation of innovative solutions around cloud, automation, and Digital Workplace environments.

Throughout my career, I have developed a strong ability to bridge the gap between business objectives and technical constraints, working within Agile and delivery-oriented approaches.

Today, I position myself as a Technical Lead / Product Owner, with a pragmatic and results-oriented approach. I support organizations in their transformation projects, combining technical expertise, team coordination, and continuous process improvement.

My goal is to deliver robust, scalable solutions aligned with business needs.
