About

I’m a Melbourne-based Data and AI Engineer who loves building technology that actually makes life better. My focus is on designing scalable, end-to-end systems that are robust under the hood yet effortless for the people who rely on them.

What drives me is impact. I’m particularly drawn to projects that strengthen society’s trust in technology - systems that are secure, transparent, and reliable. Within that, I’m especially interested in healthcare and large-scale consumer platforms, where trustworthy data systems and intelligent automation can improve outcomes for millions of people. I get excited about building real-time, automated solutions that cut out repetitive work, enable faster decisions, and give teams the tools to focus on what truly matters.

I thrive in structured environments where collaboration, clear processes, and engineering discipline come together to deliver results. At the same time, I bring curiosity, creativity, and a problem-solving mindset - because the best systems don’t just run; they evolve and adapt to what people really need.

If you’re looking for someone who combines strong technical depth with a genuine motivation to create meaningful impact, I’d love to contribute that energy to your team.
