Principal Pre-Sales Architect

Hi, I’m Duo (Neo).

I help organizations turn complex cloud, API, AI, and infrastructure problems into clear, buildable solutions.

Illustrated portrait of Duo (Neo) J.

What I do

A decade of building cloud, networks and the things on top.

I work at the seam where deep technical architecture meets the commercial reality of getting something delivered. Cloud platforms, API gateways, Kubernetes, AI integrations, regulated infrastructure — and the conversations with engineers, leaders, and procurement that decide whether any of it actually ships.

Currently a Principal Pre-Sales Architect for SaaS solutions; previously cloud and infrastructure architect for enterprise customers across AWS, Azure, and on-premise estates. Lately, a lot of my work sits at the intersection of those platforms and modern AI — figuring out what’s real, what’s safe, and what’s worth building.
