I am a Principal Software Engineer at Red Hat with over a decade of experience building scalable systems, spinning up Kubernetes clusters, and teaching AI agents how to do my job (just kidding... not really tho).
Right now, I spend my days orchestrating the Llama Stack, building agentic quickstarts for OpenShift AI, and convincing autonomous agents to cooperate.

- Languages: JavaScript, TypeScript, Python, SQL
- Frameworks & Runtimes: NestJS, Next.js, Express, Fast API, React
- Infrastructure & Ops: Kubernetes, Red Hat OpenShift, Docker, AWS, GCP, Linux
- Origin Story: It all started with an Electrical Engineering degree at UMass Dartmouth and looking at flashing router lights at State Street back in 2015.
- Way Back: Built APIs, data pipelines, and microservices for heavy-hitters like 3Play Media, VideoAmp, Disney, and 20th Century Fox.
- Before: Migrated media infrastructures to AWS and built custom RAG systems for journalists/lawyers at Bongo Media.
- Now: Teaching Red Hat OpenShift AI how to think via agentic frameworks.
