I build low-level systems and embedded software, experiment with realtime graphics, and ship developer tooling. I prefer C++ for systems work and try to keep the projects I actively maintain small, focused, and well-tested.

• Systems & embedded C++: device tooling, memory management, and CMake-based builds.
• Realtime systems: engine experiments and realtime media when I have time to explore graphics.
• Dev tooling: small utilities and dotfiles to speed up daily work.

I prioritize research and larger open-source contributions below; personal tooling at the end.

Research & core systems work:

• kokkos-memory-pool — device memory pool for Kokkos-backed code

  • https://github.com/matthew-mccall/kokkos-memory-pool
  • Low-level memory management for high-performance compute kernels; useful when you need predictable allocation behavior on devices.

• SCOREC/pcms — pcms (point localization & N-D search improvements)

  • https://github.com/SCOREC/pcms
  • I contributed point-search and higher-dimensional search improvements (2D→3D generalization, tolerances, refactoring) to the mesh query library.

Larger open-source contributions:

• SCOREC/omega_h — omega_h (Kokkos integration & memory-pool fixes)

  • https://github.com/SCOREC/omega_h
  • I contributed Kokkos integration, memory-pool fixes, and tests used by the adaptive mesh refinement library.

• open-algebra/Oasis — Oasis (CI, build, wasm tooling)

  • https://github.com/open-algebra/Oasis
  • I contribute CI and build improvements, documentation, and JS/wasm pipeline updates for the computer algebra system.

Personal tooling & examples:

• modern-cpp-dev — modern C++ examples and workshop material

  • https://github.com/matthew-mccall/modern-cpp-dev
  • Short, focused examples demonstrating modern C++ idioms and build patterns I use in teaching and small projects.

• mmccalldev — my personal site and notes (Astro)

  • https://github.com/matthew-mccall/mmccalldev
  • Source for my personal site; where I collect short posts, project snapshots, and documentation.

• Dockerfiles & dotfiles — development environment and helpers

  • https://github.com/matthew-mccall/Dockerfiles
  • https://github.com/matthew-mccall/dotfiles
  • Small, practical scripts and container setups for reproducible dev environments.

• I prefer small, well-scoped repositories per project.
• For C++ systems work I use modern CMake, static analysis, and CI when possible.
• For embedded code I prioritize deterministic behavior, clear ownership of memory, and testability where hardware allows.
