Jack developed daily supply side revenue tracking for Meso Finance on Aptos, contributing to the DefiLlama/dimension-adapters repository. He implemented a new API endpoint that aggregates and exposes revenue data, using TypeScript to handle data integration and calculation logic. The solution computes supply side revenue by subtracting fees from total revenue, providing accurate daily metrics for financial analysis. Jack’s work focused on API integration and data aggregation, ensuring that the endpoint delivers reliable and actionable information. Over the course of one month, he delivered this feature without addressing bug fixes, demonstrating focused depth in backend data processing and TypeScript-based API development.
