Youssef's Portfolio

Welcome to my Portfolio

Hi, I'm Youssef

Software Engineer | LLVM Contributor | LFortran Contributor | DMD Contributor

I work on compilers and low-level systems. Day to day that means reading a lot of C++, chasing down why a program miscompiles, and sending patches to LFortran, the D compiler (DMD) and LLVM's C library.

I like the bugs that hide three layers below where they show up, and I'm happiest when a long debugging session ends with a small, clean fix. I also write fuzz targets to break parsers before anyone else does.

About Me

I'm a third-year Computer Science student in Zagazig, and an active open-source contributor to compiler projects: LFortran, the D compiler (DMD) and LLVM libc.

I like low-level work: parsers, code generation, math libraries and fuzzing.
