Stefan Barrett

I’m a hands-on technology leader and full-stack problem solver who thrives on building practical, high-impact solutions. Currently serving as CTO/CPO at an Australian startup, I’ve worn many hats — architecting backend systems, guiding product direction, and leading releases — and I bring the same adaptability to my freelance work.

I specialize in backend development and cloud architecture, with deep experience in C#, SQL Server, Azure, GCP, IoT, AI, and Blockchain. I enjoy transforming complex requirements into simple, reliable software that scales. Beyond code, I understand the full product lifecycle: from brainstorming features and designing user-focused solutions, to running QA processes and ensuring smooth deployments.

Clients often value that I combine technical execution with product sense. I don’t just write code; I look at the bigger picture — how features will deliver value, how systems can remain maintainable, and how teams can collaborate effectively. With a background in finance and agriculture technology, I’m comfortable working in industries where compliance, data integrity, and scalability really matter.

What I offer:

• Backend & API development (C#, .NET, SQL Server)
• Cloud deployment & architecture (Azure, GCP)
• Systems that connect IoT devices with AI/Blockchain layers
• Product design input and release management
• Leadership that balances technical depth with business goals

If you’re looking for someone who can both build and think strategically, I’d love to help bring your next project to life.
