Senior🎓
Top SchoolAgoston Szepessy is a software engineer with 11 years of experience specializing in compilers, linkers, and low-level Windows tooling, currently driving ARM64EC code generation at Microsoft’s Visual C++ Compiler team. He owns the ARM64EC toolchain bring-up, added debugger and PE-analysis support, and implemented linker features like delay-load IATs and unit testing where none existed before. His work includes performance-focused intrinsics and optimizations, a history of fixing tricky compiler/linker bugs, and a notable 35% debug-build speedup from a linker type-cache implemented during an earlier internship. Based in Seattle, he mentors junior engineers new to compiler internals and brings practical expertise in the Windows ABI, calling conventions, PE format, and assembly-level debugging.
