During a two-month period, Laund Moe contributed to both the DioxusLabs/dioxus and bevyengine/bevy repositories, focusing on build systems and runtime reliability. In DioxusLabs/dioxus, Laund Moe enhanced the CLI build process by ensuring the -fuse-ld flag was correctly propagated for custom linkers, improving build robustness and compatibility across diverse environments using Rust. For bevyengine/bevy, Laund Moe developed a change-tick-based hotpatch detection resource and implemented automatic type inference for interpolation arguments, streamlining hotpatch reliability and developer ergonomics. The work demonstrated depth in system design, event-driven programming, and testing, resulting in more maintainable and reliable development workflows.
