Software engineer by training and by passion, Sebastien has always been fascinated by the impact software can have on our lives, our thinking and our societies. He has always tried to find the most effective and expressive ways to write software so that he could focus on what it could achieve, rather than how it could do it. When he first came in contact with decentralization and blockchain, he was hooked right away, but concerned at the same time: sure, it had enormous potential, but in order to realize it, it needed to involve more people, not only developers but as many people as possible in the general population. And that's why he created the ChainSkills initiative with his friend Said Eloudrhiri, and started giving conferences everywhere, producing online courses with more than 10,000 students and writing books about it. Today, in addition to all of that, Sebastien still develops mobile, web and backend applications for corporate customers and produces a French-speaking podcast, the ProofOfCast, about crypto-currencies, blockchain and decentralization, all the while travelling the world as a digital nomad.
