Rockstar🎓
Top SchoolThibault Wittemberg is a veteran mobile architect and engineering leader based in Normandy, France, with two decades of hands-on software experience and a decade in senior mobile roles. Currently leading Digital Continuity and Manufacturing engineering at Capgemini, he has designed large-scale iOS/Android architectures for high‑traffic products (millions of monthly users) and led mobile teams end-to-end from hiring to delivery. He is an active open-source contributor—known for work on RxFlow and fixes in Swift's AsyncAlgorithms—bringing pragmatic expertise in reactive, functional and unidirectional architectures. Equally at ease in deep technical refactors, CI/test automation and product-aligned architecture decisions, he pairs rigorous engineering with a founder’s mindset from running startups and a bladesmith studio. That mix of production-grade mobile architecture, open-source impact and hands-on craftsmanship makes him both a strategic leader and a pragmatic builder.
