Eight honest questions — can customers actually find, trust and contact your business right now?
Six services. Each one scoped and priced clearly.
Horn Dev keeps its offer focused on what actually moves the needle for a local business, so every engagement gets full attention rather than being one of many accounts on a spreadsheet.
Website Design
A clean, professional, mobile-friendly website — built around what your clients need to see before they contact you.
Online Shop
A custom-built shop that shows up on Google when people search for what you sell — PayFast checkout or WhatsApp order flow.
Mobile App Development
Custom Android apps for one specific operational problem — offline-capable field apps, job cards, and business process tools.
Business Automation
Quote, booking and review-request workflows that follow up automatically, reducing administrative overhead.
Practical Software
A defined operational problem, addressed with a small, purpose-built tool rather than an oversized off-the-shelf system.
A clear process, agreed upfront.
Scoping conversation
A short discussion covering your business, your requirements, and your timeline — by phone, WhatsApp or in writing.
Fixed quote
A written quote at a flat price before any work begins. No hourly billing, no scope creep without agreement.
Delivery & handover
Work is delivered on schedule, with plain-language documentation and direct support afterward.
Trades, professional practices and hospitality businesses.
A direct working relationship, not a queue.
- Direct — you deal with the person doing the work, not an account manager.
- Prompt — quotes are typically issued within a day, small projects delivered within a week.
- Transparent pricing — a fixed rate, agreed in writing before work starts.
- No lock-in — you own what's built once it's paid for.
Real, delivered — not a mockup.
JCM Custom Creations
A custom online shop for personalised sublimation printing, with orders sent straight through on WhatsApp — no account or online payment needed.
“Great service, very professional, I am very impressed.”

Founder & Developer.
Horn Dev is led directly by Petrus Horn, a software developer based in the North West. Every engagement is scoped, built and delivered by him personally — there is no account-management layer between the client and the work.
North West Province in person — remotely across South Africa.
Horn Dev is based in Rustenburg, with in-person coverage of Rustenburg, Brits and Hartbeespoort. Website design, automation and practical software don't require being on-site, so those services are available to businesses anywhere in South Africa, working remotely by phone, WhatsApp and email.
