About Laurent


Today, I am a Staff Engineer, previously a Software Architect and Tech Lead, I work on Retail ecosystems.

I have a good ability to adapt, and varied experience, and I have successfully led projects for major clients in the Retail (Leroy Merlin, Décathlon, Carrefour), energy (EDF), transport (SNCF), media (TF1, France Télévision), and defense (Thalès) sectors.

I actively contribute to the design and architecture of the projects entrusted to me. I still code with tech teams on performance issues. My preferred environments are e-commerce and web applications, on micro-services architectures, using Java and cloud technologies.

With good interpersonal skills, I support business teams in the scoping and design of application solutions for large-scale projects.

My solid technical skills enable me to support technical teams in implementations that respect business needs and constraints. I help tech teams achieve operational excellence through technical and methodological coaching.

As an architect, I lead architecture committees, scoping and audits, solution design, and write architecture documents.

My purpose is to transform an architecture into a real, functional product in production. I enjoy working in a team and co-building robust, scalable, and evolving solutions in the cloud.

I am a certified Google Cloud Architect and am comfortable in cloud and GCP environments.
