Software Engineer at HypixelStudios
Summary
🤩
RockstarJellySquid is a software engineer with 11 years of experience specializing in performance engineering and back-end systems, particularly within game engines and real-time rendering. They are a prolific open-source contributor to high-profile Minecraft Fabric projects like Sodium, Lithium, and Phosphor, where their work focuses on reducing allocations, optimizing chunk and lighting systems, and improving rendering and pathfinding subsystems. Comfortable diving into low-level performance bottlenecks, they’ve refactored critical serialization, collision, and light-update logic to cut memory use and improve frame stability. JellySquid pairs a pragmatic engineering mindset with a playful personality—“professional idiot by day, maniac programmer by night”—which fuels creative, persistent problem solving. They also pay attention to developer experience, adding configuration persistence and GUI improvements alongside heavy optimization work. Expect someone who thrives on making complex, resource-constrained systems run noticeably smoother while keeping code maintainable.

CaffeineMC/sodium
Jan 2020 - Jan 2023
A high-performance rendering engine replacement for Minecraft, which greatly improves frame rates and reduces micro-stutter
Role in this project:Back-end Developer
Back-end DeveloperContributions:17 releases, 98 reviews, 756 commits in 3 years
Contributions summary:JellySquid's contributions focused on improving the performance and functionality of the Sodium mod. Their commits included correcting text errors in the GUI, adding configuration saving logic for Sodium options, and refactoring and re-organizing code, specifically within the mixing system. They also implemented code to add new features, like accessing the vanilla options screen and allow for custom formatting of option values within the GUI. The changes also contain significant work towards a new chunk renderer, along with optimizations for OpenGL rendering.
