Full Stack Developer & Designer

about
me

I'm a Full Stack Developer with 25+ years of professional experience across graphic design, branding, business ownership, and operations — and a Master's in Mathematics & Computer Science.

After decades of making things look right, I trained to make them work right too. I completed the _nology Full Stack Engineer program in early 2026, and I now build practical, user-focused applications that are both technically solid and visually considered.

I bridge design and development — and years of client work, business ownership, and team management mean I bring strong communication and collaboration to every project.

Currently deepening my knowledge in cybersecurity and AI. Based in Melbourne, open to remote work worldwide.
