Senior WordPress & WooCommerce developer
Custom plugins, automations and external system integrations — I build online stores that are secure, fast and genuinely pleasant to use.
A developer who understands the business side
I am Sándor Ferenczi, a senior WordPress–WooCommerce developer. To me an online store is more than code: it is a working business where every element serves revenue and the customer experience.
The real work begins where ready-made templates reach their limits — where you need a custom feature, an automation, or the precise integration of an external system. These are the tasks I design and build, from the first line to the last.
What I build
Custom solutions tailored to your store's real needs — from the backend to the design.
Custom WordPress plugins
Bespoke WordPress and WooCommerce plugins from scratch, built precisely around your processes. One example is my own ÁrHarcos (Price Fighter) dynamic pricing plugin.
- Custom WooCommerce features
- Update-proof, maintainable code
- Plugins developed as products of my own
Custom backend functions & automations
Background processes that take the routine work off your shoulders: automatic data processing, scheduled tasks and tailored admin interfaces.
- Custom admin functions
- Scheduled and event-driven automations
- Data processing and synchronisation
Integrations with external services
I connect your store to the outside world — reliably, using API, XML and many other connection methods.
- Product feeds and price comparison sites
- Payment gateways (e.g. Viva.com)
- PPC data, shipping carriers, invoicing services
Bespoke design
I tailor the look to your needs as well — working either from a finished Figma design or from a simple written brief.
- Pixel-accurate Figma implementation
- Design from a written brief
- Responsive, on-brand interfaces
What matters most in my work
Three priorities guide every decision — without them there is no good online store.
Security
Protecting the store and customer data is not optional, it is the foundation. I write secure, update-proof code.
Loading speed
A fast site means more customers and better rankings. I treat speed as an integral part of development.
User experience
Good UX lives in the details. I build interfaces that are a pleasure to use.
