Joomla Development
Development and care of Joomla websites — from company sites to multilingual portals, with custom components, modules and templates.
Joomla — flexible, multilingual and strong without extra plugins
Joomla is a proven open-source CMS that ships with more than many alternatives: true multilingual support without an extra plugin, a fine-grained user and permission system and a clean separation of content, structure and presentation. That makes it strong for portals, associations, educational institutions and multilingual company sites.
Custom extensions instead of compromises
Where standard extensions hit their limits, I build tailored components, modules and plugins — cleanly following the Joomla MVC architecture, so they stay updatable and maintainable. You get exactly the feature your project needs, without overloading the install with third-party extensions.
Migration to Joomla 4/5
Many Joomla sites still run on the outdated version 3. I guide the upgrade to Joomla 4 or 5 — including a rebuilt template, a review of extensions and content migration, without data loss.
When Joomla beats WordPress
I do not pick the system by preference but against a short list of criteria. Joomla is ahead when at least two of these apply:
- Tiered editorial permissions: several user groups with different access levels — the Joomla ACL covers this in core, at no extra cost.
- Front-end editing: officials or editors maintain content directly on the page, without any backend access.
- Structured content: nested categories and custom fields instead of page-builder patchwork.
- Lean installation: as much functionality as possible without third-party extensions and their licence and update costs.
For blogs, landing pages and WooCommerce shops, WordPress usually remains the more economical choice — see the article Which CMS fits your project? for a detailed comparison.
Security and update routine for Joomla sites
Most hacked Joomla sites that end up on my desk share the same problem: abandoned third-party extensions. My counter-routine is unspectacular but effective: a monthly update check on a staging copy, a backup before every update, consistent removal of unused extensions and enabling Joomla’s built-in two-factor authentication for all backend accounts. I also check the official vulnerable-extensions list — if an installed extension appears there, it gets replaced or rebuilt in-house.
From practice: a multilingual association portal
A typical Joomla scenario: an association with a site in German and English, a public area and a protected members’ section. Built entirely with core features — language associations for all articles and menus, ACL-protected categories for minutes and internal documents, front-end editing for the secretary. Not a single commercial plugin, no recurring licence fees. Projects like this are exactly where Joomla plays to its strengths.

Frequently asked questions about Joomla development
Is Joomla still worth it compared to WordPress?
Yes — especially for multilingual sites and fine-grained permissions. Joomla brings both without extra plugins, while WordPress needs them added on.
Can existing Joomla sites be migrated?
Yes. I guide the upgrade from Joomla 3 to 4 or 5 including template, extensions and content — controlled and without data loss.
Do you build custom Joomla extensions?
Yes. When no suitable extension exists, I build components, modules and plugins cleanly along the Joomla MVC structure so they stay updatable.
Is Joomla suitable for multilingual websites?
Very much so. Multilingual support is part of the Joomla core and can be implemented cleanly per language with its own menus and content.
Joomla development — websites, components, templates & migration
Joomla development is the right choice for multilingual websites, portals and community projects that need more structure out of the box. As a proven open-source CMS, Joomla brings true multilingual support without an extra plugin, a fine-grained user and permission system and a clean separation of content and presentation. I develop and maintain Joomla websites on the current versions Joomla 4 and 5.
Custom Joomla components and modules
Where the extension catalogue hits its limits, I build tailored components, modules and plugins — cleanly following the Joomla MVC architecture so they stay updatable and maintainable. You get exactly the feature your project needs, without overloading the install with third-party extensions.
Individual templates and design
Instead of an off-the-shelf template, I build an individual Joomla template — based on Cassiopeia/Atum or as a fully custom design that fits your brand and works cleanly on every device.
Migration from Joomla 3 to Joomla 4/5
Many Joomla sites still run on the outdated version 3, whose support has ended. I guide the Joomla migration to version 4 or 5 including a rebuilt template, a review of extensions and migration of all content — controlled and without data loss. That keeps your website secure, fast and future-proof.
