Summary

Infrastructure specialist with 15+ years of hands-on IT experience, currently at a managed service provider where I administer Microsoft 365 tenants, deploy and monitor endpoints via Datto RMM, and drive security hardening initiatives. I design and operate a self-hosted multi-node platform (Docker Swarm, Traefik, Authentik, Vault, N8N) and build production tools in Go, React, Python, and PowerShell. I integrate AI into daily workflows as a force multiplier — not a novelty — maintaining persistent knowledge bases so each session compounds on the last.
