About Arthur

I structure technical organizations.

My job: to join a company where tech is disorganized, quickly understand the product, the team, and the business challenges, then implement the organization, processes, and architecture that enable delivery.

What I bring concretely:
— Technical audit of your platform and prioritized action roadmap
— Structuring of tech teams (recruitment, processes, quality, roadmap)
— IS Architecture and integration of complex systems (ERP, CRM, PIM, API)
— Management of service providers and multi-team coordination
— Platform modernization and technical debt reduction
