I’m a hands-on IT professional with deep roots in infrastructure, Microsoft 365, networking, and automation. I build practical systems that reduce manual work — including local-first AI workflows, reporting automation, and tooling that fits real operational constraints.
I’ve been building and fixing systems since I was a kid — from assembling PCs and wiring networks to running business-critical cloud services. Today I manage Microsoft 365, endpoint/app ecosystems, and frontline IT, while designing automation and local-first AI tooling that helps teams move faster without adding risk.
I formed Zero Point Dynamics to package what I do best — automation, infrastructure, and practical AI integration — into deployable solutions for small/medium businesses that need results without enterprise bloat.
