The Problem

When standard plugins are not enough

Plugin Overload

You need 10 plugins for one feature. Each plugin brings its own CSS, JavaScript and potential security vulnerabilities.

Update Issues

After every WordPress update you hold your breath. Will the plugin still work? Or will everything break again?

Slow Website

Too many plugins slow down your site. Google penalises you, visitors bounce – and you lose revenue.

The Solution

Bespoke WordPress Development

Vincent Kilchherr - WordPress Programmierer

I am Vincent, WordPress developer from Basel.

As a PHP developer, I understand WordPress from the inside out – and know how to write clean, maintainable code.

Instead of installing 10 plugins, I develop a bespoke solution for you. Less code, more performance, no conflicts.

  • ERP integration – connect inventory management

FAQ

Frequently asked questions

Yes, I analyse your existing plugin code and extend it with new features. The prerequisite is clean, documented code. With messy code I often recommend a new development.

Yes, WooCommerce plugins are a focus area. Whether special checkout fields, product options, discount logic or interfaces to inventory management – I know the WooCommerce hooks and APIs.

I develop to WordPress Coding Standards, use own namespaces and test with common themes and plugins. Before launch I check compatibility with your specific installation.

Yes, I develop custom blocks for the Block Editor using React and the WordPress Block API. This way your features integrate seamlessly into modern WordPress editing.

I test your plugin against beta versions of new WordPress releases. With maintenance contracts I adjust the code proactively. Without a contract you can commission updates as needed.

This depends on the scope. Simple plugins are ready within a few days, complex solutions take several weeks. After the initial conversation I give you a realistic estimate.
