Hello, I’m Fred

I am a software engineer currently based in Vienna, Austria. I prefer to focus on Linux application and system development using C, C++ or Rust and I have a strong passion towards designing software around correctness and performance.

I am currently a member of the team developing PowerDNS at Open-Xchange.

Previously, I worked as a member of the team developing the Sulong LLVM Runtime for GraalVM at Oracle.

Before that, I worked on symbolic execution of Java and Go, developed solutions to automate the analysis of RF engine models at Intel and worked on research in high performance computing for PRACE.
