Though his career often pushes him toward management, he stays close to the code, drawing on 15 years of shipping software and publishing research. He focuses on programming language mechanics and finding better ways to catch bugs before production. In his talks, he breaks down unusual type systems—like Rust's affine ownership and Agda's dependent types—into practical mental models that developers can use without needing a computer science degree. ## Past Sessions ### World Congress 2026 Europe · July 8, 2026 Berlin, Germany - [Type Systems You Might Not Know (But Will Love)](https://www.wearedevelopers.com/videos/100067-type-systems-you-might-not-know-but-will-love) · 30 min · 🎥 Watch recording ## Videos - [Type Systems You Might Not Know (But Will Love)](https://www.wearedevelopers.com/videos/100067-type-systems-you-might-not-know-but-will-love) · Veit Heller ## Links - [LinkedIn](https://www.linkedin.com/in/veit-heller/) - [Blog](https://blog.veitheller.de/)
