Selected Projects
What was the starting point, what did I do, what came out of it. Three projects, told openly.
Gerwing Steinwerke
Gerwing manufactures paving stones – in a league where hardware stores buy from them. When I joined in 2023, the existing shop needed a fundamental redesign: better user guidance, a working sample ordering system, clear paths for dealers and end customers.
I rebuilt the entire shop from scratch. WooCommerce as the base, but heavily customized: a stone sample ordering system with email tracking, product filters by color, format, and application area, price groups for different customer types.
The result: A shop that serves both audiences – end customers who want inspiration, and dealers who need to order quickly. Since then, I maintain the shop alone. One contact, short paths, direct implementation. → More about online shops
Runden Group
Runden Group is a family business with subsidiaries in recycling, logistics, IT, building planning, and agriculture. Each company needed its own website – uniform in appearance, but individual in content.
I built the entire web presence: 11 websites on WordPress with YOOtheme Pro, each bilingual (DE/EN), plus a career portal and a podcast section. The designs came as Figma mockups – everything else I derived and implemented.
For two years, I was solely responsible for the entire web presence of this corporate group. Updates, content maintenance, new features, technical issues – all came across my desk. This is the project I mention when someone says: "One person can't possibly maintain a corporate group." → More about project management & frontend
WBG Pooling
WBG Pooling rents out reusable transport packaging across Europe. The website goes far beyond a company presence – it's an industrial portal with interactive 360° product views, a circular economy diagram explaining the pooling process, and a job board integration that automatically syncs open positions.
On top of that, a password-protected sales center for distribution partners. The foundation: WebDeck – a custom plugin I developed for onboarding and training portals. Quiz system, progress tracking, PDF certificates, role-based content. The same system powers employee onboarding for other clients.
I also connected the contact forms to Salesforce (Web-to-Lead), so inquiries land directly in the client's CRM. This project shows what happens when a website doesn't stop at "looks good." → More about custom solutions
