From music to infrastructure — a career built on orchestrating complex systems
The Foundation
30 years as a professional musician — founding a 20-piece Big Band, designing music education networks for municipalities, and performing in New York City. I learned to orchestrate complex systems, lead under pressure, and adapt fast. My album title says it all: "Your Comfort Zone Will Kill You."
The Transition
Dove headfirst into DevOps through Develeap's rigorous 16-week bootcamp and intensive self-study across Python, CI/CD, cloud, and Kubernetes. Earned AWS SAA and CKA certifications. Built deep, practical experience across the full infrastructure lifecycle from day one.
JFrog
As a DevOps Support Engineer, applied FinOps using Terraform and Lambda across AWS Organizations — eliminating 80% of cloud waste and cutting monthly spend by 30%. Mastered deep troubleshooting across enterprise-level infrastructure, networking, and performance issues.
Today
Platform Engineer and AI Systems Architect at Polus Tech — leading the full migration of an edge intelligence platform to a 13-microservice K3s cluster with FluxCD GitOps, and architecting AI-Ops ingestion pipelines using RAG, n8n, and AWS Bedrock. Open to roles in cloud infrastructure, platform engineering, and AI-driven systems.
