My expertise in WordPress
No more slow sites that break with every update. I build professional WordPress setups that last, handle heavy traffic and turn your visitors into clients.
01
Custom theme development
I don't recycle heavy, generic premium themes. I code your own WordPress theme from scratch for optimal performance and a design that reflects your brand 100%.
Optimised architecture
Clean, lightweight code
Exclusive design
Hardened security
02
Online shops (WooCommerce)
Turn visitors into buyers with an online shop that feels smooth and trustworthy. I build optimised sales funnels, secure payments and simple order tracking so your business is easy to run.

Redesign and optimisation of your current site
Does your current WordPress site take 10 seconds to load and drive clients away? I analyse the structure, clean the database, remove unnecessary plugins and drastically improve performance and technical SEO.

Admin interface (ACF)
Running a website shouldn't require technical knowledge. I fully customise the back office (admin dashboard) so your team can add new content without any fear of breaking the layout.

WordPress powers almost half of the world's websites. It's an outstanding tool, provided you know how to use it properly. My technical approach rules out slow, unstable page builders. I favour native code (PHP, React) combined with the power and flexibility of WordPress. Google and your visitors see the difference straight away: your site loads instantly, security is stronger, and you keep full ownership of your files and database.

Frequently asked questions about WordPress
Can't find what you're looking for? Get in touch directly, I always reply within 24 hours.
Get in touchAnyone can install a free theme, but the result is often a very slow site, open to hacking and identical to your competitors'. As a professional developer, I code your WordPress site from start to finish (custom theme). Your site will be unique, very fast, secure and built to please search engines.
A professional WordPress business website, with a unique, cleanly coded design and no bloated page builder, starts at CHF 2,500. If you need a complete online shop (WooCommerce) optimised to sell, budgets start at around CHF 3,000, depending on the number of products and integrations required.
Yes. The very structure of a well-built WordPress site is excellent for SEO. On top of that comes my technical optimisation work. I guarantee very short load times, a clean tag hierarchy and the best SEO tools built in, so you can write your content with peace of mind.
That's the big advantage of WordPress. I use ACF (Advanced Custom Fields) to build you a clean, custom admin interface. You won't need to touch any code to edit your text, add blog posts or upload new photos. A short video training session is also included at handover.
WordPress sites need regular updates (core, plugins, PHP) to stay secure. I offer a monthly plan (or one-off maintenance) covering backups, security audits and technical updates. That way you can focus entirely on your business.
