Rockstar🎓
Top SchoolAaron St John is a Senior Engineer specializing in production AI systems with eight years of experience building full-stack solutions that move from prompt design to observable, cost-efficient deployments. Based in Knoxville, he architects cloud-native infrastructure on AWS with Terraform and ships custom agents and RAG pipelines using services like Amazon Bedrock, Lambda, ECS/Fargate, and DynamoDB. His background spans data science and analytics—forecasting with Databricks, Snowflake, and XGBoost/Prophet—so he blends rigorous modeling with pragmatic engineering to push prototypes into reliable production. Aaron also contributes to open-source UI work (notably UX improvements to the TrueNAS web UI), reflecting a practical attention to user-facing details as well as backend scale. He’s driven by solving hard problems end-to-end and prioritizes building systems that last.
