The Founder

Rachelle Tseng — 20+ Years. Every Layer.

Enterprise IT, government systems, healthcare software, full-stack development, e-commerce, automation, and creative services — one person, one business, every technology challenge.

One Person.
Every Capability.

I started in IT over 15 years ago and have worked across some of Australia's most demanding environments — from government infrastructure at Victoria Police, to complex healthcare data systems, to running the full technology stack for multi-site retail and e-commerce operations.

Along the way I've built custom software, migrated enterprise servers, upgraded hundreds of business reports, set up VoIP systems from scratch, designed and launched e-commerce stores, automated workflows that used to take hours, and even picked up a camera to shoot product photography when the job called for it.

HAZON UNITY is the business I built around that breadth of experience — to offer Australian businesses a single, trusted technology partner who can handle the full picture, not just a slice of it.

Our Approach
We build solutions that actually work for your business — not generic tools that sort of fit.
01
Custom-First Philosophy

Every solution is built specifically for your business. No bloated templates with features you'll never use.

02
Real Business Experience

Government, healthcare, enterprise, and SMB — 20+ years of solving real operational problems across sectors.

03
End-to-End Ownership

One point of contact from discovery through delivery and ongoing support. No handoffs, no gaps, no excuses.

Technology That Pays For Itself

Most technology consultants handle one discipline. A web developer. A network engineer. An IT support company. When you work with specialists in silos, nobody owns the whole picture — and the gaps between them are where problems live.

HAZON UNITY was built differently. Rachelle's career spans the full technology stack — from government infrastructure and healthcare systems to e-commerce development and automation. That means she understands how each layer connects to every other, and can design solutions that work together rather than just individually.
