Worked on the rh-hideout/pokeemerald-expansion repository to enhance UI performance and overworld visual fidelity in a C-based embedded game development environment. Focused on optimizing the party UI by updating only the affected party icon sprite during movement operations, which eliminated flicker and improved player interaction. Addressed overworld sprite accuracy by updating palette management and sprite configuration for specific Pokémon forms, ensuring correct visual representation in the game world. The work emphasized business value by reducing render churn and enhancing the overall player experience. Demonstrated depth in embedded systems, palette management, and game development through targeted, maintainable feature delivery.
