About Us
NS Management Consultancy Ltd
Established 2011 • stackandsystem.com launched 2026
At our core, we are educators. Stack & System exists to make software architecture and system design accessible—completely free, without barriers, and through richly detailed tutorials that anyone can follow.
Before you build a system, you need to understand its architecture. Before you scale, you need to know the patterns. Our ever-growing library of tech tutorials bridges that gap—transforming complex architectural concepts into clear, example-laden lessons.
Headquartered in Milton Keynes, United Kingdom
We combine deep technical expertise across software architecture, cloud-native technologies, and engineering leadership with hands-on educational content designed for lasting understanding.
