Summary
🤩
Rockstar🎓
Top SchoolThomas Villaren is a Senior Staff Software Engineer based in Paris with 11 years of experience building and scaling low-code platforms and compliance-critical systems. He has been a key driver of JetLang at PayFit, evolving it into a modular, event-driven platform that enables country-specific payroll compliance across Europe and embedding AI pipelines to extract legal parameters from new regulations. Thomas moves fluidly between hands-on engineering and organizational design, applying Domain-Driven Design to align teams and architecture during hypergrowth and restructuring phases. His background blends research and product: a PhD in cognitive science and early R&D work on model-driven low-code tooling inform his focus on usability, automation, and reducing friction for product teams. He also has experience in human factors and HMI from academic and industry projects (including a MIT research visit), which gives him a rare cross-disciplinary view on complex systems. Colleagues describe him as the pragmatic “glue” who balances technical debt, speed, and long-term platform strategy.
