Summary
👤
Senior🎓
Top SchoolThomas Pierrain is a pragmatic engineering leader and VP of Engineering with 13+ years of experience building production-ready, low-latency systems and guiding teams through DDD, TDD and XP practices. Based in Lyon, he combines hands-on architecture and .NET expertise with a strong track record in event-sourced, CQRS and reactive systems across domains from hospitality and finance to healthcare. He has led API and platform transformations, mentoring autonomous teams and moving organizations from hero-driven to sustainable, Kanban-powered delivery. An active practitioner and open-source author (creator of NFluent) who also speaks publicly, he brings a developer-first mindset—obsessed with use cases rather than solutions—that surfaces elegant, testable designs. Less obvious: his background includes building bi-temporal event-sourced “time machine” platforms for asset managers, demonstrating a rare focus on temporal correctness and auditability.
