"We build systems that outlast the technology cycle."

Our Approach

Disciplined design, careful state management, and a bias toward maintainable, testable code.

Whether it's stabilising critical infrastructure, building AI-powered document systems with RAG and vector search, or crafting precision music tools, we bring the same engineering rigour to every project.

About

Greenwood IT Consultancy is a London-based software consultancy with over two decades of hands-on engineering experience. We specialise in complex, long-lived systems where reliability, security, and delivery under real-world constraints matter more than novelty.

Our expertise spans the full stack, from Azure cloud architecture and DevOps pipelines to native iOS/macOS development with Swift and SwiftUI, and down to real-time audio DSP with C++ and JUCE.
