During August 2025, Haris contributed to the haristic/slow-hack-demon-list repository by delivering the core data assets required for the Cosmic Dreamer v2 level content in the app. Haris focused on data definition and management, using JSON to model new level metadata, update the content index, and encode semicircle geometry data for enhanced level listing and visualization. The work involved designing and synchronizing data pipelines to ensure seamless integration of new content, demonstrating a thorough approach to asset creation and index maintenance. While no bugs were recorded, the depth of the feature work reflects careful attention to data structure and repository organization.
