Building full-stack systems that feel alive.

Five years deep into product engineering across modern web, mobile, AI-assisted workflows, and battle-tested legacy platforms. I design, build, refine, and ship digital products with both visual intent and backend discipline.

Professional trajectory

A career built between
legacy reliability and modern experimentation.

I learned by shipping. Freelance work sharpened range, corporate work sharpened delivery discipline, and ongoing academic study is adding deeper systems thinking to both.

Academic foundation

Self-taught drive, formalized with computing study.

Currently pursuing a BSc in Computing at the University of South Africa (UNISA), deepening practical experience with theory in software engineering, data structures, and systems analysis.

The result is a profile that can shift from visual experimentation to durable systems thinking without losing product intuition.

Let’s build something with presence

Looking for products that need strong engineering, visual confidence, and a developer who can move between both.
