Worked on the zipline-ai/chronon repository to expand cloud-native data ingestion and streaming capabilities, focusing on scalable and resilient backend systems. Developed features such as Kinesis integration for Flink with shard-aware parallelism, DynamoDB bulk ingestion using Ion format, and robust error handling for optional GCP dependencies in AWS environments. Enhanced schema management by implementing automatic schema format detection for AWS Glue and supporting richer JSON Schema types with local loading. Introduced AWS STS assume-role authentication for secure Kinesis cross-account access. Leveraged Python and Scala, emphasizing unit testing, stream processing, and improved developer tooling to ensure reliability and maintainability.
