Four products. All live. Every one with a live reference client. You're not funding a build from zero — you're getting a production-proven foundation, adapted to your business, branded as yours.
We built the frameworks. We own the code. That's what makes us faster and cheaper than an agency — not because we cut corners, but because the hard problems are already solved.
Every product in the portfolio has a live reference client already running it. You're getting a production-proven foundation, adapted to your business and branded as yours.
You get the software, the setup, and ongoing maintenance on a monthly retainer. Agency-quality software at a fraction of the cost and time.
Solo builder means you work directly with the person who makes every technical decision, writes every line, and is still reachable six months after you go live.

An end-to-end internal operations platform for a consulting firm — projects, timesheets, leave, expenses, skills matrix, staffing search and performance reviews. Role-based access, real-time data, mobile-ready. Built white-label so it can be redeployed for any consulting business.
I'm a solo builder — not an agency — which means you work with the person who makes every technical decision, writes the code and is still reachable six months after you've gone live.
Background spans enterprise SAP data engineering at scale — lead on Africa's largest SAP Retail rollout — to consumer mobile apps with real user traction built and grown solo. I know what it takes to get software from idea to production and keep it there.
Based in Cape Town. Available for contract builds from early brief through to deployed, stable and working.
App that needs building, a system that needs untangling, or a data problem that needs solving. Contract basis — from brief to production-ready.
