Message

At Cowbell, I’m leading the transformation of a fragmented data platform into a unified, configuration-driven ecosystem for cybersecurity risk intelligence. I architected GlueFlux, Cowbell’s in-house YAML-driven ETL/ELT orchestration engine for AWS Glue and ECS.

I designed a cloud-native data services platform and modernised the Amazon Redshift warehouse with a Bronze-to-Gold Medallion architecture. I’m also connecting Redshift pipelines to AWS Bedrock and SageMaker for AI-powered risk scoring.

Earlier at Cowbell, I developed risk pools for US, UK, and Japan markets and helped make data available in under 10 minutes instead of 12 hours. At Nineleaps, I worked on self-serving data pipelines and managed large data streams using Apache Spark, Kafka, and Hadoop.
