Summary
🤩
RockstarMaja Kądziołka is a systems-minded software engineer with 9 years of experience building and optimizing low-level tooling, compilers, and security tooling. She contributes to flagship open-source projects like the Rust compiler—improving Clippy, MIR, and type checking—and extends architectures and tooling in pwntools for exploit development. Comfortable across C, Rust, and Python, she has deep experience in emulation, decompilation and linker/toolchain internals (SameBoy, rgbds, pokeruby). A functional-programming enthusiast and self-described math nerd, she enjoys working on proof-assistant-adjacent problems and compiler ergonomics. Her work blends rigorous correctness (error reporting, non-exhaustive handling) with practical performance and build-process improvements. Based in Poland and often "near my computer," she brings quiet focus and a knack for making complex systems more maintainable and reliable.
