I build custom applications
that live inside your existing platform.
Your WordPress, Shopify, or WooCommerce site does most of what you need. But there is one thing it cannot do. A course selector. A credit system. A plan comparison tool. A custom dashboard. I build that missing piece as a custom application embedded directly in your platform. Your site stays. Your content stays. Your SEO stays. The application is added on top.

What happens when you hit your platform's ceiling
You have tried every plugin
There are 60,000+ WordPress plugins and hundreds of Shopify apps. You have tried the ones that come close. They almost work, but not quite. They do 70% of what you need, or they conflict with your theme, or they break every time the platform updates. The problem is not the plugins. The problem is that your requirement is specific to your business.
Theme hacks are fragile
Your developer added custom code to your theme to make it work. It worked for a while. Then a theme update broke it. Or a plugin conflict broke it. Or nobody remembers what was changed and now everyone is afraid to update anything. Theme modifications are temporary fixes that create permanent anxiety.
No-code tools hit their limits
Zapier, Make, Airtable, Typeform. You connected them together and it worked until it did not. The logic got too complex. The data flow got unreliable. You need something that is built specifically for your workflow, not stitched together from generic tools.
Other developers want to rebuild everything
You asked a developer for help and they said: "You should rebuild the whole site." That means losing years of content, SEO rankings, customer accounts, and institutional knowledge. You do not need a new site. You need a new capability added to the site you already have.
Custom applications for your existing platform
WordPress Custom Applications
React applications packaged as WordPress plugins. Embedded into any page via shortcode. Their own API layer, their own database tables, their own admin interface. Completely isolated from your theme and other plugins. Platform updates do not break them.
Typical work: Course selectors, product configurators, dashboards, calculators, multi-step forms, plan comparison tools, admin management interfaces.
WordPress Development›Shopify Embedded Applications
Custom applications embedded in your Shopify storefront or admin. External API server with its own database and business logic. Connected to Shopify via Storefront API, Admin API, or App Bridge. Independent of your Shopify theme.
Typical work: Credit systems, loyalty dashboards, custom product builders, enrollment flows, ERP sync interfaces, customer portals.
Shopify Development›Custom API Servers
Every custom application needs a brain. I build dedicated Node.js API servers that handle your business logic, store your data, and communicate with your platform and third-party services. Your data, your rules, your control.
Typical work: REST APIs, webhook handlers, ERP integrations (Exigo, Sage, Xero), payment gateway connections, real-time data synchronization.
API Development›WooCommerce Extensions
When WooCommerce plugins cannot handle your checkout logic, product configuration, or pricing rules, I build custom extensions that work within WooCommerce but add the specific functionality your store needs.
Typical work: Custom checkout flows, conditional pricing, product configuration tools, inventory rules, payment gateway integrations (PayFast, Peach, Ozow).
WordPress & WooCommerce›Custom applications in production
ICA Course Selector (WordPress)
Inspection Certification Associates needed a state-specific course selection system for their US home inspection training programs. No WordPress plugin could handle the logic. I built a custom React application embedded directly in their WordPress site via shortcode, with a separate admin interface in WordPress admin and a custom REST API connecting both. Their WordPress site was not modified. The application was added as a plugin.
View project›Truly Essential Credits System (Shopify)
A US e-commerce company needed a loyalty credit system inside their Shopify store that tracked purchases, synced balances with Exigo ERP, and gave customers a self-service dashboard. No Shopify app could do this. I built a custom React application embedded in their Shopify storefront with its own Node.js API server and MySQL database. Bidirectional ERP sync. 99.9% uptime in production.
View project›MedXpert Plan Selector (WordPress)
Optivest needed a modern medical aid plan selection tool to replace a legacy form system. It had to be responsive, handle complex multi-step logic, and communicate securely with the WordPress backend. I built a React application embedded as a WordPress plugin with custom REST API endpoints, persistent state management, and secure nonce authentication. Their existing WordPress site was untouched.

These are not theoretical skills — I have shipped production applications with all of them.
Technologies I Use
Your platform stays. I add the application. It runs independently but looks like part of your site.
Every custom application I build is architecturally isolated from your platform. It communicates through APIs, not theme hooks or core modifications. This means your existing site, content, SEO, and functionality are completely unaffected. The application can be updated, extended, or removed without touching anything else. This is not a hack or a workaround. It is a deliberate architectural pattern that ensures your investment in your existing platform is preserved.

How It Works
Tell me what your platform cannot do
Describe the feature, tool, or workflow that your WordPress or Shopify site needs but does not have. I will assess whether a custom application is the right approach or if a simpler solution exists.
I review your platform and propose a solution
I look at your existing site, understand the data, the users, and the logic involved. Within 48 hours I respond with an approach: what gets built, how it integrates with your platform, and what the scope looks like.
Build, integrate, and launch
The application is built and tested independently, then integrated into your live site. Your existing platform continues to run throughout. No downtime. Post-launch support included.
Typical Engagements
Custom platform applications vary based on complexity and integration requirements:
- Focused custom tool: a specific calculator, selector, dashboard, or form with defined logic and a single integration point.
- Multi-system application: custom applications with their own API server, database, and connections to external services like ERPs, payment gateways, or third-party APIs.
- Ongoing platform extension: iterative development of new features and capabilities added to your platform over time.
Your platform is the foundation.
I build on top of what you already have. If your WordPress or Shopify site works, I am not going to tell you to throw it away. I am going to add the thing it cannot do.
Frequently Asked Questions
Can you add a custom application to my existing WordPress site without breaking it?
Yes. The application is built as a self-contained module (typically a WordPress plugin) that runs independently inside your site. Your existing pages, content, SEO, and theme are not touched. If you ever remove it, your site continues to work exactly as it did before.
Will my existing SEO and content be affected?
No. The custom application lives on its own page or section within your site. Your existing pages, URLs, content, and search rankings are completely unaffected.
How does a custom application work inside Shopify?
The application runs as an external service with its own API server and database. It is embedded into your Shopify storefront using Shopify App Bridge or script injection. Customers see it as part of your store, but the logic and data live on a separate server. Shopify theme updates do not break it.
Do I need to rebuild my site to get custom functionality?
No. That is the entire point. I build custom applications that extend what your platform already does. Your site stays exactly as it is. The application is added on top.
What happens when WordPress or Shopify releases an update?
Because the custom application is isolated from your platform theme and core, platform updates do not break it. The application communicates through APIs, not through theme hooks or core modifications.
What is a single page application?
A single page application (SPA) is a web application that loads once and updates dynamically without reloading the page. It feels fast and responsive, like a native app. The custom applications I build for WordPress and Shopify are single page applications embedded directly into your platform.
What can your platform not do today?
Tell me what feature, tool, or workflow is missing from your WordPress or Shopify site. I will assess whether a custom application is the right solution and respond within 24 hours.
