Work Experience

Programming Language Engineer, Chapel

Hewlett Packard Enterprise | Summer 2022 - Present
  • Added support for compile-time reflection, various language keywords, and full scope resolution to compiler written in C++.
  • Designed and implemented a type-safe error reporting API, improving developer experience and compiler error messages.
  • Enabled rapid protyping of language tooling such as linters by developing Python bindings for compiler front-end.
  • Supported community growth by designing, launching, and authoring articles for the Chapel language technical blog.
  • Laid groundwork for compatibility with leading-edge supercomputers by implementing initial AMD GPU programming support using Clang and ROCm tooling.

Research and Teaching Assistant, Programming Language Theory

Oregon State University, Corvallis, OR | Spring 2018 - Summer 2022
  • Formalized denotational and operational semantics of new explanation-oriented programming languages.
  • Developed tooling in Haskell to interpret, verify, generate, and debug programming languages.
  • Contributed to research papers published to the GPCE and VL/HCC.
  • Proctored quizzes and exams for over 200 students.
  • Aided students in implementing a final project in the form of a custom programming language.
  • Suggested and organized independent review sessions attended by over 70 students, with 50% attendance growth between sessions.

Front-End Intern, Hydrogen

Element.io | June 2021 - September 2021
  • Spearheaded migration of codebase to TypeScript, improving documentation and discovering hidden bugs.
  • Leveraged advanced type system features to precisely specify nontrivial program properties.
  • Developed a mocking system to help specify and test corner cases in a distributed communication system.
  • Independently implemented user-facing features including offline-first replies and sanitized HTML rendering.

Additional Experience

Technical Writer

Independent | Spring 2015 - Present
  • Designed and published website currently live at danilafe.com.
  • Authored blog posts on topics spanning data structures, web development, programming languages, and compilers.
  • Formalized and described solutions to select Advent of Code problems using the Coq proof assistant.
