Worked on enhancing Sablier data integration within the DefiLlama-Adapters repository by implementing targeted filtering at the Envio endpoint and updating related GraphQL queries. Focused on backend development using JavaScript, the work introduced category-based filtering for flow and lockup contracts, ensuring that only relevant data is retrieved and processed. Adjustments to indexers and queries aligned the data pipeline with the new logic, improving both performance and accuracy of Sablier-related analytics. This approach reduced payload size and irrelevant data, enabling faster indexing and more reliable results. The work demonstrated effective use of API integration and backend optimization techniques throughout the project.
