Worked on the reown-com/blockchain-api repository to enhance RPCAnalytics data export processes, focusing on improving AWS S3 export prefix management. Implemented a clear separation between pos_build and pos_check data exports, which streamlined data organization and facilitated more efficient retrieval for downstream analytics. Standardized export path handling across different environments to minimize configuration drift and ambiguity, ensuring consistent and reliable data exports. The work leveraged Rust for backend logic and integrated AWS cloud services for scalable data export and analytics workflows. These changes improved the maintainability of data pipelines and prepared the system for more robust analytics and reporting capabilities.
