How I Work

One Builder.
AI-Orchestrated. Shipped.

I'm entirely self-taught — no degree track, no bootcamp, just 15 years of learning whatever the problem demanded. Today my working method is simple: I direct AI the way a conductor directs an orchestra. The architecture, the judgment, the verification, and the responsibility are mine; the typing is delegated. It's how one person ships what used to take a department — in production, with real money flowing through it.

01 / LEARN

Any Domain, Overnight

New industry, new API, new physics — tell me about it today and I'll understand it well enough to build in it tomorrow. Learning fast isn't a phase I went through; it's the core skill.

02 / DIRECT

AI-Orchestrated Engineering

I've spent years mastering how to drive AI tools to production quality — prompting, decomposing, reviewing, testing. The result: team-scale output from a single chair, without team-scale cost.

03 / SHIP

Production, Not Demos

Everything on this page runs (or ran) in the real world — real clients, real transactions, real uptime requirements. Prototype speed, production standards.

About

The Architect Behind
the Systems

I started in 2009 building websites from a smallholding outside Cape Town. Fifteen years later I'd run Pure Web Solutions for a decade and a half, served as CTO of GAS Marketing Automation and Technical Lead of PropInvest at the same time — a complete technology department of one, twice over — and shipped AI systems used by millions.

Today I'm CTO at PropInvest, where I've built the company's entire operations platform: CRM, deal capture, WhatsApp / SMS / email messaging, AI-driven ad generation, website and mobile-app CMS, stock control, automated invoicing, and reporting — one integrated system, one architect.

Next up: a first-of-its-kind SaaS platform for a new venture. Details under NDA. Watch this space.

Concept to deployment across the whole stack: web apps, mobile apps, APIs, databases, hosting and VPS infrastructure — 15 years of running it all myself.

📊
