01 Starting point
Systems engineering is not sold on catalogue prices. Enquiries come once someone understands what a supplier can actually solve and whether it knows their industry. So the site has to explain the range of services and the reference projects without cutting away the technical detail.
WordPress is an obvious choice for that, and that is exactly why the same problem tends to appear: a page-builder theme plus twenty plugins gets a site up quickly, then delivers slow pages, update conflicts and an attack surface nobody can survey any more.
02 Solution
The site runs on WordPress with a theme we wrote for it. Instead of configuring a bought multipurpose theme, we built the parts that are actually needed: service areas, reference projects, contacts and an enquiry route with consistent fields.
The plugin list is deliberately short. Anything that can be solved in a few lines of PHP in the theme is solved there. That cuts update dependencies and keeps load times under control. For editors the rule is: defined blocks in the editor rather than free formatting, so the site still looks as planned after the hundredth post.
Operation and maintenance can sit with one team here: core and plugin updates, backups and monitoring, plus keeping the installation on PHP 8. Hosting is on our own servers in Germany. An out-of-date PHP version is the most common reason older WordPress sites eventually stop moving.
03 Result
The company can extend the site itself. A new service or reference project is assembled from existing blocks, without anyone touching the theme. At the same time the technical base stays predictable, including updates and restore if something goes wrong.
