About

25 years of infrastructure architecture behind every engagement. From the largest Cisco contact center deployment in the world to the first 5G network on public cloud.

Greg Stewart

Founder & Principal Architect

Cloud Foundations was built on 25 years of infrastructure architecture — from the largest Cisco contact center deployment in the world to the first 5G network on public cloud. Our founder, Greg Stewart, spent 5 years at AWS as a Control Tower subject matter expert and lead infrastructure architect, delivering landing zones for some of the most demanding environments on the platform.

At AWS, Greg led the infrastructure for the first cloud-based customizable 5G network (10M+ endpoints), designed the IoT Smart Home platform that cut tenant onboarding from a week to an hour, and built the multi-tenant clinical drug trial platform that enabled global expansion in 2 hours instead of 2 weeks — all on Control Tower landing zones with GxP and NIST 800-53 compliance.

Before AWS, Greg spent 7 years at TTEC deploying the largest Cisco Hosted Collaboration Solution for Contact Center in the world — 60+ enterprise customers across 10 global data centers. And before that, 6 years at State Farm designing and supporting one of the largest domestic enterprise networks, including a 200,000+ endpoint telephony migration.

That experience is now the foundation of everything we deliver — the same rigor applied to a 4-person AI startup that was applied to a 10-million-endpoint 5G network.
