I built parts of the site (subcontractor)

Operator delivers tailored IT and communication solutions, covering data, voice, mobile, and support services. 

I migrated the Operator website from Drupal 7 to Drupal 10 (as a prototype). To simplify content input and the creation of new sections, the new site was built using Drupal’s Layout Builder, with several reusable components configured for the client’s convenience. Maintaining the exact look and feel of the original site was essential to the client, so the theme was accurately ported one-to-one.

“Meininger’s International” was developed by the Online Team, with my contribution limited to adapting an existing theme, some theming, and some minor module coding.

The MIXOLOGY Bar Awards are held annually to celebrate excellence in the bar and cocktail scene across German-speaking Europe. They recognize the most innovative and influential bars, bartenders, and industry professionals who are shaping modern bar culture through creativity, hospitality, and craftsmanship.

The "Made in GSA" Competition is a prestigious annual cocktail contest celebrating regional spirits and ingredients from Germany, Switzerland, and Austria—hence the acronym "GSA." Organized by Mixology magazine, it’s the largest independent cocktail competition in Central Europe.  It’s a platform for bartenders to showcase their craft using local ingredients, with a strong focus on storytelling and drink experience.

The site is dedicated to bar culture. It’s a vibrant hub for bartenders, cocktail enthusiasts, and industry professionals, offering deep dives into spirits, cocktail recipes, bar trends, and the people shaping the scene.

Founded in 2003, Mixology has grown from a niche magazine into a full-fledged platform. The site also hosts the prestigious Mixology Bar Awards—often dubbed the “Oscars of the bar world”—and organizes the Made in GSA Competition, a cocktail contest spotlighting regional ingredients.

Get-In Kongress Website:  Drupal development and theming for a multi-day beverage industry conference

The “Get-In Kongress” is a multi-day event hosted by Meininger Verlag, bringing together key players in the beverage industry. The website serves as a central hub, showcasing the event program, speaker lineup, and a live blog during the conference.

“Finest Beer Selection” is a prestigious international beer tasting competition, where breweries from around the world submit their finest brews to be judged by a panel of experts.

The website combines two previously separate platforms: the tasting logic from Meininger’s wine competitions and a WordPress-based informational site about the “Finest Beer Selection.” These elements were merged into a unified Drupal site. To maintain consistency, the visual design of the original WordPress site was preserved and applied across all tasting-related pages.

Subcontractor for an agency which develops this site.

Overall, an E-commerce shop was built by the other agency using a Magento Shop System.

I created a web service interface that connected the shop with a logistics company which ships large appliances to the end-customer. This service and interface was then connected with the Shop System.

For a digital studio, I developed a digital asset management system which was used to track resources on web projects, and lead an offshore development team in China.

The project used model-driven design with round-trip software/UML engineering: changing the UML automatically changed the software classes and vice versa: the design was the software. This kind of visual software design was invaluable in helping to communicate with a software team that was half-way around the earth and did not speak English that well.

This client runs a website for streaming TV.

When they hit the limits of what they could developed themselves, they called me in to develop the solutions along very strict technical requirements. 

This included

• switching TV-channels using Ajax,
• a complicated user management system with main and sub-users;
• specialized access controls,
• automatic recognition of terminal-hardware and subsequent automated login,
• and much more.

Furthermore, I enhanced the same customer’s online-billing system.
