Background
Nicolas Martignole has been building software since the late 1990s. A Java, Scala and web developer, he has worked as a freelancer, tech lead, CTO and partner, head of an IT services company and then Principal Engineer. This path has given him a hands-on understanding of tech, from code to organizational and investment trade-offs.
Before joining Back Market in January 2024, he was a Principal Engineer at Doctolib from 2021 to 2023, where he worked on architecture, observability and crisis management at scale. He previously ran Lunatech in France and served as CTO and partner at CaptainDash.
He has shared this hands-on experience for many years on Le Touilleur Express. As co-founder of Devoxx France, he has also contributed since 2012 to one of Europe’s leading developer conferences.
