About me

Background & Skills

I'm a backend-focused software engineer with a strong foundation in Java and enterprise systems. After building my career in South Africa, I moved to the Netherlands to broaden my horizons and work in international teams.

I thrive in collaborative, high-impact environments, take full ownership of the solutions I build, and genuinely enjoy mentoring others and sharing knowledge.

My Dutch fluency has grown to the point where I can comfortably work in fully Dutch-speaking teams, contributing effectively in day-to-day collaboration and communication.
