Sacha Clerc-renaud is a Staff Software Engineer based in Paris with 11 years of experience designing and shipping resilient backend systems, particularly in banking and fintech. He has led core banking efforts at Spendesk and Shine, architecting event-driven, CQRS-based systems to guarantee account balances and robust workflows for card issuance and payments. At Phacet he now applies that domain expertise to building AI agents for finance, blending reliability-first engineering with emerging AI tooling. Sacha is comfortable moving between hands-on implementation and cross-team coaching—he’s driven design standards, internal SDKs and microservice frameworks, and trained teams on Domain-Driven Design. Notably, he has repeatedly turned complex partner integrations and error-prone processes into auditable, self-healing workflows that reduce operational load. He combines deep Node.js/Postgres experience with production-grade distributed systems thinking and a penchant for practical automation.
