Worked on enhancing billing data storage and analytics capabilities for the neondatabase/autoscaling and neondatabase/neon repositories. Introduced per-event billing records using NDJSON, transitioning from JSON arrays to newline-delimited JSON for more efficient downstream processing and analytics. Refined the S3 key strategy by shifting data partitioning from daily to hourly, enabling regional storage and more granular data access. Standardized key formats and implemented gzip compression to optimize storage and transfer efficiency. Leveraged Go and Python for backend development, focusing on API integration, cloud storage, and data serialization. These improvements reduced processing latency and supported scalable analytics for billing and capacity planning.
