At Sightline Signals, I built a production GenAI diagnostic platform as its sole engineer, spanning ingestion, vector pipelines, agent reasoning, security, CI/CD, APIs, and the delivered application. Its RAG engine uses Mosaic AI Vector Search and Model Serving, with MLflow tracing and evaluation that helped cut inaccurate diagnostic output by 58%.
At Fiserv, I modernized multi-terabyte analytical workloads from Oracle to Databricks Delta Lake and Snowflake, cutting platform infrastructure costs by 60%. I also built GoldenGate CDC pipelines into Databricks while financial systems continued processing live transactions.
At NASA Artemis Program, I ran databases across AWS GovCloud under FedRAMP and FISMA requirements, and automated vulnerability scanning, configuration management, and patching with Python. That automation cut manual effort by around 40%.
Earlier, at GM Financial, I led upgrades for 70+ Oracle RAC databases from 12c to 19c across AWS and Azure. My earlier work included setting database architecture for the Marine Corps GCSS-MC ERP upgrade and supporting a federal modernization to Oracle Supercluster.
