Industry experience

1. C++ Software Engineer, OrcaSlicer / CrashSlicer fork

   Nov 2025 to Present

   Open source, freelance | C++17, wxWidgets, Dear ImGui, OpenGL, CMake

   • Built desktop GUI features (ImGui, wxWidgets, OpenGL) for a large open source 3D slicer: toolpath preview, transient unit system controls, timeline UI.
   • Built nonplanar slicing driven by mesh surface normals, and a windowed G-code preview for inspecting path segments.
   • Authored upstream PR #13168: a transient unit system swap in the Move and Scale gizmos using XOR based flipping and per frame ImGui state, writing no preference values during a temp hold.
   • Iterated that PR through maintainer review: refactored a standalone module into the existing unit display layer, and rebound a hotkey after a contributor raised a keyboard layout conflict.

2. Facilities Technician: 3D Printing and Laser Cutting, CRASH Space

   Oct 2024 to Present

   501(c)(3) makerspace | 3D printer maintenance, teaching, facilities upkeep

   • Maintain an FDM print farm (Prusa, Bambu) and two CO2 lasers; author and teach the facility's 3D printing and laser cutting classes.
   • Build the space's web tools and drive the slicer fork's roadmap from recurring member failure modes.

3. Software Engineer (Games): C++ Systems and Tooling, Sovereign Axe Studios, Super Evil Megacorp, Deviation Games

   April 2020 to Present

   • Architected C++ class structures and core runtime systems for character, combat, and progression, designed for extensibility across growing content teams. (Sovereign Axe, current)
   • Wrote C++ and custom scripting tooling that let designers implement complex systems independently, measurably improving team iteration speed. (Super Evil Megacorp)
   • Designed and implemented a data driven weapon and attachment system in C++ with scripting exposure, supporting dynamic property combination across component types. (Deviation Games)
   • Extended a proprietary engine with new developer facing capabilities, landing changes with the core engine team that met internal code standards.
   • Worked in multithreaded runtime environments: async asset loading and frame loop bound systems under real time performance constraints.
   • Shipped on TMNT: Splintered Fate; promoted from Associate Gameplay Engineer up to Senior Technical Designer.
