About Me

I am a multidisciplinary IT professional and the founder of Vylex, based in South Africa. Driven by curiosity and a passion for technology, I combine formal education, including a Diploma in Systems Development (NQF Level 6) from Boston City Campus, with continuous self-directed learning.

My approach is broad by design. I believe a developer who understands the full stack, from the underlying physical hardware to the interface a user touches, builds superior software. Starting with a strong foundation in IT support and networking, I have evolved into a full-stack developer capable of conceptualizing, designing, and deploying comprehensive web, native mobile, and enterprise applications.

I design reliable and scalable systems utilizing industry best practices like DRY (Don't Repeat Yourself) and KISS (Keep It Simple). By embracing AI-assisted development tools like GitHub Copilot and Claude, I accelerate iteration and dedicate my energy to complex, strategic problem-solving.
