Ouvert aux opportunités
Attracted to software quality since early professional years, my various experiences allowed me to enhance my skills, eventually leading me to become technical referent, then technical leader, within a team of 40 people including 25 developers, spread across Paris, London and New York.
My skills in architecture, optimization and functional analysis made me work on two brand new trading platform development projects.
In these projects, I have initiated and leaded a DevOps transition to ensure better quality in delivery in a sensitive domain.
Subsequently, my role as solution architect and DevOps leader allowed me to improve my expertise in this domain, applied to cloud, by solely managing multiple critical GitLab instances in High Availability Mode with full automation on infrastructure, software, metrology and disaster recovery plan fields to secure projects for 5000 developers.
Working in the technical office, I had the opportunity to initiate improvements in multiple fields: infrastructure-as-code, security, development environment, best practices.
