About Me

Builder. Architect.
Entrepreneur.

I'm a passionate software engineer and tech entrepreneur from Johannesburg, South Africa. My journey started with a love for programming that quickly evolved into building real products and leading engineering teams.

Today, I work as a Solutions Architect at Untamed Technologies, designing scalable systems and technical strategies for clients across industries. Simultaneously, I'm the Managing Director and Founder of LocknAlert — a smart security platform changing how people protect what matters most.

Beyond code, I'm a Digico-certified sound engineer, an avid mountain biker, and someone who genuinely believes technology should solve real problems for real people.

What I Do For Fun

When I'm not building software or running a startup, you'll find me doing these.

Mountain Biking

Nothing clears the mind like hitting the trails. Mountain biking keeps me grounded and gives me the headspace to think through complex problems.

Sound Engineering

As a Digico SD5 certified engineer, I mix live sound professionally. There's real art in making a room feel the music — much like making software feel effortless.

Programming

Programming is both my work and my passion. Building this site is proof — why pay someone else to do what you love? The process of creating something from nothing never gets old.

Contact

Let's Work Together

Have a project in mind, a problem to solve, or just want to connect? My inbox is always open.

Get In Touch

Whether it's a new project, a collaboration, or just a hello — I'd love to hear from you.
