# Jonathan Müller
Core library engineer at think-cell and assistant chair for C++ std::ranges.

## About

Jonathan Müller maintains core C++ libraries as a software engineer at think-cell. He helps shape the language on the C++ standardization committee, serving as the assistant chair for `std::ranges`.

Outside of work, he builds open-source C++ tools like the `foonathan/memory` allocator, the `lexy` parser, and the `lauf` bytecode interpreter. His talks dive into core language mechanics, breaking down functional programming concepts and the finer details of object lifetimes, memory allocation, and compiler optimizations.
