Summary
👤
Senior🎓
Top SchoolLouis Ledey is a Staff Backend Engineer based in Paris with 13 years of experience building scalable microservices and leading backend teams in fast-moving fintech and mobility environments. At Qonto and previously Kapten, he has combined hands-on Node.js/TypeScript development with architecture design, system migrations, and operational delivery for cross-border projects. He routinely mentors engineers, runs recruitment and career development processes, and acts as a pragmatic bridge between product and engineering to keep roadmaps aligned and on schedule. His background includes working with message-driven systems (RabbitMQ), MongoDB, and occasional Go and React work, reflecting a full-stack sensibility despite a backend focus. Notably, he led a complex 10-month migration between Kapten and FREE NOW that required multi-team coordination across countries and product teams. He brings a steady mix of technical depth, people management, and delivery ownership to scaling engineering organizations.
