Summary
🤩
Rockstar🎓
Top SchoolDavid Longnecker is a software engineer with 7 years of experience focused on compiler and back-end development for the Chapel parallel programming language at Hewlett Packard Enterprise. He contributes to core compiler improvements—refactoring variable types, implementing new parsing features like include and manage statements, and streamlining intent and storage-kind handling—which demonstrates deep systems-level expertise in language design. Based in the Greater Seattle Area, he blends practical engineering with academic foundations from The Evergreen State College. Colleagues rely on him for readable, maintainable compiler changes that reduce parser errors and enable new language features, an often unseen but critical part of shipping robust parallel programming tools.
