Boson Protocol is an open protocol for decentralised and agentic commerce: a buyer's money is held in escrow until the item is delivered, and redemption and disputes are handled on-chain. Ludovic joined as Lead Developer in March 2021. The protocol is audited by Omniscia and PeckShield and live on Ethereum, Polygon, Base, Optimism and Arbitrum. In 2026, LX Foundry works with the Boson team.

The roles below match public commit history, and each links to the record. Some Boson repositories are private, so they appear here only where a public package shows the work exists.

   Joins Boson Protocol as Lead Developer

   Boson Protocol · 2021 to today ↑

Nineteen years in the aerospace industry, where requirements are written down before anything is built and every integration is verified. Most of LX Foundry's engineering habits come from there.

• EngineeringDeveloper
• IntegrationSystem & software integrator
• ManagementSystem engineering manager
• DeliveryDevOps team lead

Those habits include writing requirements before code, treating integration as an engineering discipline, keeping verification auditable, and building delivery pipelines that make releases uneventful. They now shape how we direct AI coding agents, as described in how we build.
