Florian Valeye is a Founding Engineer and seasoned data platform leader with eight years of experience building scalable, production-grade data infrastructures across startups and large enterprises. Based in Bordeaux, he has driven data strategy and execution at Back Market—rising from Lead Data Engineer to Senior Staff—where he designed event-driven architectures, GDPR data contracts, and a generative AI platform for internal use. He now focuses on making data "agent-ready" via the Model Context Protocol (MCP), architecting backends that let AI agents navigate complex datasets autonomously. A committed open-source contributor and Delta Lake committer, Florian has improved core Rust-based tooling (delta-rs) around S3 storage, schema handling and decimal support, bridging low-level engineering and data interoperability. Trained as an engineer (ENSEEIHT) with a Master’s in Management of Technology (Dauphine), he combines deep systems craftsmanship with product-minded leadership. Colleagues describe him as the kind of engineer who sees data not just as assets to store, but as active interfaces for intelligent systems.
