Darwin's Software Specialists Since 2004

IT Business Solutions has operated in Darwin since 2004. It is Aaron Leonhardt's practice, and Aaron is the only engineer you will work with.

The Founder

Aaron Leonhardt

Founder & Principal Software Engineer

Aaron Leonhardt has been building software in Darwin for over 20 years, working across NT Government, local councils, utilities, and private enterprise. His clients include the NT Department of Health, Darwin Waterfront Corporation, Power and Water Corporation, and the Royal Darwin Show Society, among many others.

When you work with IT Business Solutions, you work directly with Aaron. No account managers, no outsourcing, no offshore teams. Every line of code is written by someone who will also answer the phone when something goes wrong.

Aaron works across the full enterprise stack, from Oracle database architecture and VB.NET application development to modern .NET WebAPI services and Azure cloud infrastructure. His systems are built to last: the Annual Return Web Application he wrote in 2005 is still in production today, without a single bug fix required in over five years.

Founded in Darwin

IT Business Solutions was established in Darwin, NT, with a focus on delivering tailored software for Territory organisations.

Early Years

Government Partnerships

Secured first major NT Government contracts, building a track record of delivery that has sustained the business for two decades.

Mid 2000s-2010s

Portfolio Growth

Delivered BushTel, the Aboriginal Interpreting Service system, Grants Management System, and dozens more critical applications.

2010s-2020s

Modern Stack Evolution

Expanded into modern .NET WebAPI services, Azure cloud, and web-based interfaces. Legacy system support continued in parallel — the two are not in conflict.

Today

Trusted Territory Partner

Over 20 years on, IT Business Solutions remains the trusted choice for NT organisations that need software built right and supported for the long term.

Honest Partnership

We tell you what is possible, what it costs, and what the risks are. Clear language, honest scope, no pressure to add unnecessary work.

Built to Last

Our systems are engineered for longevity. We care about what happens in year ten, not just on handover day.

Local Commitment

Darwin is home. We are invested in the Territory's growth and understand its operating environment.
