From VoIP, Windows Server migrations, DNS and web server configuration to Crystal Reports, custom WordPress and Shopify development, business automation, livestreaming, and photography — HAZON UNITY delivers integrated technology that drives real results.
From the moment a business idea forms to full operational maturity — HAZON UNITY covers every layer of your technology lifecycle. Most consultants handle one or two stages. We handle all five.
One partner. Every layer of your technology stack — designed, built, and supported.
Design, supply, and configure enterprise-grade VoIP systems for businesses of any size. Cloud-based, on-premises, or hybrid — with ongoing support and management.
Custom websites, Shopify storefronts, WordPress themes and plugins, extensions, integrations, and internal applications — built to your exact specifications, not off-the-shelf templates.
End-to-end livestream production for events, business broadcasts, product launches, and content creation. Multi-platform streaming with professional audio and video setup.
Professional commercial, product, and corporate photography. High-quality visuals for websites, marketing, catalogues, and brand building.
Upgrade and modernise your entire business IT environment — servers, networking, DNS configuration, web server setup (Apache/Nginx/IIS), VPN, SSL certificates, cloud migration, security hardening, and backup systems. We handle the full stack from planning to go-live.
Eliminate repetitive manual tasks through smart automation. From inventory sync and order processing to reporting and multi-system integrations — we make your business run on autopilot.
Custom business reporting built in Crystal Reports — from scratch or migrating legacy reports to modern versions. Complex subreports, cross-tabs, parameterised dashboards, and full ERP/database integration.
End-to-end Windows Server migrations with zero data loss and minimal downtime. From planning and scoping to execution and post-migration support — including roles, Active Directory, IIS, and application compatibility.
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.

Designed and engineered complex healthcare application components, automated back-end data sync workflows, and built XML-based systems for chronic illness management platforms. Healthcare compliance and data security experience.
Full-stack development, LAN management, IT team leadership and training. Built web applications using MySQL, ASP.NET, PHP, and JavaScript for multi-site retail chain operations.
Developed government-grade web applications, custom SQL reporting systems, SMS fault notification systems, and Access database solutions for critical police infrastructure. Highest security and reliability standards.
Web development, database design, multimedia production, and systems integration across multiple industries. Adobe Creative Suite, PHP, JavaScript, SQL, and CMS development.

400+ Crystal Reports upgraded, multiple Windows Server migrations, government-grade systems development, and large-scale business automation across complex environments.
HAZON UNITY is founded and led by Rachelle Tseng — a bilingual IT systems specialist and developer with 15+ years of hands-on experience across enterprise infrastructure, full-stack development, business automation, and creative services.
Rachelle's career spans government (Victoria Police IT Department), healthcare systems (Precedence Health Care), multi-site retail IT operations, and e-commerce development — giving her a uniquely broad perspective on how technology actually functions inside real businesses under real pressure.
From a three-person trades business to a growing retail operation — if your technology isn't actively helping you grow, it's holding you back. HAZON UNITY was built to fix that, one business at a time.
Real projects. Real outcomes. Names withheld to protect client confidentiality.
Designed and built a real-time inventory synchronisation system connecting a point-of-sale ERP to two Shopify storefronts. Automated stock level updates, order processing, and reporting — eliminating manual reconciliation and preventing overselling across all sales channels.
Built a fully custom Shopify order print action extension with complex business logic including delivery codes, multi-currency display, and conditional discount handling.
Built and modified custom WordPress themes and plugins tailored to specific business requirements — beyond what standard templates offer. Includes custom post types, advanced ACF layouts, WooCommerce extensions, and performance optimisation.
Migrated legacy Microsoft Access databases to SQL Server with seamless integration, built custom reporting via SSRS, and resolved 32/64-bit compatibility issues across business systems.
