My team was responsible for establishing architectural patterns, developing cloud services for event-driven security automation and policy enforcement, operational hygiene, automated monitoring and logging, and cost optimization to enable Intuit's products to run fully in AWS.
  • Built a search query service which aggregated events (AWS CloudTrail & Config) across all AWS accounts and provided attribution and auditing for changes made to production resources. Service was originally built atop ElasticSearch but was later re-designed to use S3 and AWS Athena resulting in significant cost savings.
  • Developed a Python-based service for delivering 300k+ time series metric points/second from all of Intuit's cloud services to a monitoring platform, resulting in significant latency reduction and cost savings.
  • Maintained and enhanced a service that aggregated metadata for all AWS resources, providing real-time inventory across thousands of AWS accounts. Improved the service's overall uptime and scaled support for new AWS services by 50%.
