About
Software engineer with a focus on compilers, LLVM, and high-performance computing. I work mostly in modern C++ — extending frontends, writing analysis passes, and optimizing code at a low level. I have contributed to projects like Clang, Flang, and tree-sitter, and I enjoy the kind of problems where performance actually matters.
