Senior🎓
Top SchoolCẩm Huỳnh is a co-founder and Head of Engineering with 12 years of experience building robust back-end systems and leading engineering teams from Gothenburg. He combines hands-on Elixir expertise—evidenced by contributions to cornerstone projects like Elixir, Phoenix, and Ecto—with product-level leadership at startups such as Iris.la and Forza Football. Known for improving core language and framework internals (compiler correctness, String optimizations, JSON/socket serialization), he moves confidently between prototype and production concerns. As Technical Lead he balances architectural direction with active code contributions, especially in fault-tolerant data layers and adapter implementations. Outside work he’s a dedicated “true blue” and part-time dumpling maker, a hint at a pragmatic, detail-oriented approach that carries into his engineering practice.
