Work

Apple Software Engineer Jun 2019 - Dec 2021, Stockholm 🇸🇪

I worked on various parts of the LLDB debugger. Main focus was maintaing the LLVM-based expression evaluator within LLDB, but also various other stuff related to debugging with LLDB.

Apple Software Engineer Intern Jun 2018 - Aug 2018, California 🇺🇸

I was supposed to add code completion support to LLDB's expression evaluator. But I ended up implementing a bunch of other stuff too (including the syntax highlighting support. You are welcome fellow LLDB users).

CERN Technical Student Jan 2017 - Dec 2017, Geneva 🇨🇭

Worked on Clang's initial C++ modules implementation and CERN's C++ interpreter ROOT.

GSoC Google Summer of Code Student May 2016 - Aug 2016, Remote

Implemented semantic error detection within Clang's static analyzer.
