Rockstar🎓
Top SchoolTorbjörn Törnkvist is a seasoned engineer with decades of hands-on experience in Erlang since 1991 and a track record of building resilient, production-grade systems across startups and large enterprises. He helped architect network and controller solutions—most notably creating the Tail-f OpenFlow controller before Tail-f was acquired by Cisco—and has been at Cisco since 2014. Comfortable across languages and platforms, he explores Rust, Elixir, Kotlin and Python, recently hacking on Android software and AI applications. His career spans telecom exchanges, compiler work, 24/7 payment systems at Klarna, and on-call operational ownership, giving him deep expertise in fault-tolerant distributed systems. Based in Stockholm, he pairs technical curiosity with practical delivery and an unusual blend of low-level systems thinking and modern language experimentation.
