Worked on the tonkeeper/ton-assets repository to deliver a YAML-based configuration for Roaring Kitty jetton metadata, establishing a single source of truth for token attributes such as name, description, address, and symbol. This configuration-driven approach standardized asset metadata, improving data quality and ensuring consistency across downstream services and user interfaces. Leveraged skills in configuration management and asset metadata modeling, with a focus on version-controlled YAML files to streamline onboarding for new jettons. The work laid the foundation for scalable asset data management and future updates, supporting more reliable search and UI experiences without addressing major bug fixes during the period.
