## About

```text
At DataLocker, I maintained and enhanced SafeConsole, a secure USB device management platform. I traced CPU spikes to transaction-per-event ingestion and shipped a multi-client batching layer that cut database CPU from ~60% to 10–20% at peak.

I also re-architected the Java log-ingestion pipeline from MySQL to OpenSearch and built a common adapter layer for SIEM integrations. When runtime log-level changes caused configured SIEM appenders to disappear, I added a reconciliation check that made delivery self-healing.

At the U.S. National Institutes of Health, via Multivision & Leidos, I designed and maintained 20+ Java REST and SOAP services for federal health data systems. I led an incremental modernization of Oracle stored procedures and batch processes while live portals kept running, and delivered Angular and JSP front ends.

I’ve also built a medical test-kit e-commerce application at AndPlus and authored Java tutorials for Baeldung. In my independent projects, I’m developing privacy-first educational games and a portable pack of AI agents, using spec-driven development and human-reviewed changes.
