Worked on the GeyserMC/Geyser repository to address a critical cross-version compatibility issue between Java and Bedrock editions. Focused on backend development and protocol translation using Java, the work involved correcting inconsistencies in dimension height calculations by distinguishing between maxY and height values in Java dimensions. Adjusted the Bedrock chunk section array sizing to accurately reflect dimension heights, which improved world chunk rendering and reduced visual glitches. This targeted bug fix enhanced stability and chunk handling across versions, ensuring that both Java and Bedrock clients experienced consistent world rendering. The contribution demonstrated depth in game development and backend systems integration.
