About Me

I'm a passionate full-stack developer from Melbourne, VIC, with a strong foundation in both frontend and backend technologies. My expertise spans AI integrations, modern web frameworks, and enterprise-level solutions.

With a Bachelor of Engineering (Honours) and Commerce from the University of Sydney, I combine technical depth with business acumen. I specialize in building scalable microservices, intelligent algorithms, and user-centric applications.

My approach focuses on writing maintainable, well-documented code while applying design patterns and best practices. I thrive in collaborative environments and enjoy solving complex problems that push the boundaries of what's possible.
