Summary
👤
Senior🎓
Top SchoolJohn L is an incoming Software Engineer at Microsoft with 11 years of hands-on experience building backend systems, distributed ML infrastructure, and HPC workflows. He blends practical systems programming—evidenced by WinRT enhancements to the widely used OpenZWave C++ library—with cloud-scale features like SFTP POSIX ACLs for Azure Blob Storage. His background spans research and production: from uncertainty-aware ML and selective learning at Argonne to implementing consensus and HPO tooling during undergrad research at UC San Diego. Comfortable across C++, C#, Go, Python and MPI, he has shipped full-stack internal tools and hardened IoT onboarding services while addressing real-world authentication and device issues. A longtime Vim enthusiast, he brings a productivity-first mindset and low-level debugging skillset that often surfaces in platform compatibility and performance work.
