Fridtjof works on the Fuzion programming language. He is Chief Programming Language Designer and CEO at Tokiwa Software GmbH.

Dr. Fridtjof Siebert has a long history of implementing compilers, run-time systems and analysis tools for different programming languages on a wide range of platforms. His latest project is the Fuzion language and its open-source implementation.

In the 90s, he developed the Amiga Oberon compiler as a side-project to finance his studies at the University of Stuttgart. After implementing a compiler for Eiffel on Solaris/SPARC as his diploma thesis, he became part of the Open Software Foundation / The Open Group team in Grenoble that implemented the TurboJ Java compiler.

During his PhD at the University of Karlsruhe he developed the technical foundation for the JamaicaVM hard-real-time Java implementation. He was founder of the aicas GmbH and served aicas as CTO for 18 years developing their Java technology further to support hard-real-time GC on multi-cores on a large range of real-time OSes and CPU architectures and adding dynamic and static analysis tools such as the VeriFlux static analysis tool for Java byte-code.

Since 2019, he works as Chief Programming Language Designer for the Tokiwa Software GmbH where he develops the Fuzion language and tools, a new open-source programming language that combines a powerful syntax and safety features with simple base concepts that enable strong static analysis and highly efficient optimizing compilers.
