Home / Shopify Developer, Cape Town
Custom Shopify engineering, not theme tweaks, from a developer in Cape Town.
When Shopify’s app store can’t do it, I build the custom piece. Based in Cape Town, working across South Africa.
Does this sound like you?
- “The Shopify app store has something close to what we need, but not exactly what we need.”
- “We want our store balances or credits synced with our own system, not just Shopify’s.”
- “We’re running a campaign or signup flow that needs a security check Shopify doesn’t offer out of the box.”
- “We asked our usual Shopify help for this, and it’s outside what theme or app work can do.”
What I’d do.
Work out if this is really custom engineering.
Most Shopify requests are theme or app work. I’ll tell you plainly if that’s what you actually need, and point you to someone who does it well.
Build the piece that doesn’t exist yet.
A verification flow, a credit system synced to your other software, or a signup process Shopify doesn’t offer on its own.
Ship it without breaking your theme.
The work sits alongside your store, tested and documented, so a future theme update doesn’t undo it.
Proof.
A limited-edition campaign, gated without a server.
A secure, server-free way to check who could buy, built and deployed inside Shopify’s own secure checkout tools.
See the verification flow project →A credit balance that stays in sync with the back office.
A credit and balance system syncing in real time with a client’s own stock and accounts system, with an embedded dashboard customers use to check their balance.
See the credit system project →I am very satisfied with the assistance.
There’s no fixed price list.
A focused build gets a private quote once I understand what you need. Where access or integration risk makes that irresponsible to quote blind, the first step is a separately paid piece of work.
For your technical person
What this covers
- Checkout Extensibility: secure post-purchase flows, token-based validation, encrypted client-side logic, Shopify policy compliant.
- ERP and data sync: bidirectional sync with Exigo ERP, real-time balance updates, webhook pipelines, automated commission and loyalty tracking.
- Embedded applications: React apps inside Shopify storefronts and admin via Shopify App Bridge, decoupled from the theme so it survives theme updates.
- Identity and security: OTP verification, multi-factor authentication, tokenisation, audit logging for sensitive operations.
No theme installs or app-store configuration work; that’s out of scope and referred elsewhere. Remote delivery across South Africa is the default; in-person meetings in the Cape Town metro area are available when useful.

Questions owners ask.
Are you a Shopify developer based in Cape Town?
Yes. I build custom Shopify applications: verification flows, credit systems, enrollment platforms and ERP integrations. My company, Villiers Vision Works (Pty) Ltd, is registered in South Africa.
Do you do Shopify theme customisation?
No. My Shopify work is custom application engineering, building functionality that does not exist in off-the-shelf apps or themes. For theme changes or basic store setup, I can point you to other local developers who specialise in that.
What kind of Shopify projects have you delivered?
Three production systems: a post-purchase verification flow for Shopify Plus, deployed in under 5 days, a hybrid credit system with Exigo ERP integration, and a multi-step enrollment application with OTP verification and automated PDF generation.
Can you meet in person in Cape Town?
Yes. I am available for in-person meetings in the Cape Town metro area when the project calls for it. Most work is managed remotely, but face to face is always an option.
Do you work with Shopify Plus?
Yes. I have built inside Shopify Plus Checkout Extensibility: a secure post-purchase verification flow with token-based validation, encrypted client-side logic and privacy-first data handling, at no extra server cost.
