Summary
🤩
RockstarAlex Parrilla is a seasoned technologist and current Captain at the NYC Department of Correction with 15 years of experience blending operational leadership and deep systems development. Based in New York, he brings low-level, backend expertise demonstrated by substantial open-source contributions—most notably enhancements to Wiremod’s Expression 2 scripting in the Garry’s Mod community and internals work on the Rust ncollide collision library. His contributions show a focus on robustness, language features, and C-interoperability, reflecting comfort with both application-level scripting environments and performance-sensitive systems. Equally at home managing teams in high-stakes public service and shipping meticulously engineered code, he quietly bridges real-world operational discipline with rigorous software craftsmanship.

dimforge/ncollide
Aug 2020 - Aug 2020
2 and 3-dimensional collision detection library in Rust.
Role in this project:Back-end Developer
Back-end DeveloperContributions:5 commits, 2 PRs, 3 issues in 4 days
Contributions summary:Alex contributed to the `ncollide` library by exposing internal data structures and implementing new functionalities. Their work involved modifying the `TriMesh` structure, adding methods to access adjacent vertices and faces, and implementing the `project_point_with_feature` method. The user also added `#[repr(transparent)]` to a struct and exposed internal types, indicating a focus on low-level details and potentially C interfacing. These contributions suggest a focus on improving the library's internal workings and feature set.
