Elliott has repeatedly delivered measurable impact, including multi-million dollar AWS cost savings, dramatic reductions in bot-driven fraud, and production services that survived critical enterprise outages. He excels at eliminating waste and creating ephemeral, testable infrastructure and event-driven architectures that make systems easier to change. Based in Austin, he pairs deep operational experience across AWS, Terraform, Snowflake, and serverless patterns with a practical obsession for enabling others to do things they once thought impossible.
