Millions of setlists at your finger tips
setlist.fm editor app
With millions of monthly visits, setlist.fm is one of the most popular music services worldwide and enables its users to share their knowledge about concert setlists. The team from Molindo set out to relaunch the core experience of editing setlists and hired me to implement the user interface.
The frontend of the project consists of four React widgets. These integrate seamlessly with the existing web stack of the platform and communicate with a GraphQL API. To live up to the high expectations of mobile apps, the implementation places special focus on touch gestures, useful animations, runtime performance and an offline-first approach to data.

“The cooperation with Jan was excellent as always. As a designer, I can rely on the fact that the product is implemented pixel-perfect and on time.
What I particularly appreciate about Jan is that he also thinks about how to take a design one step further. He proactively contributes to how the product can be improved even more. I am already looking forward to all upcoming projects!”

High-performance commerce platform
The Webgears Group connects more than 300,000 online shoppers on a daily basis with over 12,000 advertising partners worldwide. The company integrates a modular web platform into the websites of publishing partners to inform consumers about current deals.
I proposed a modernised architecture for the platform based on React & Next.js that puts performance at its center. The new architecture allows for theming per publishing partner, while sharing relevant code via a component library. As a multi-year endeavor I helped the in-house team transition to the new platform, launching 13 partner apps, with more on the horizon.

Building blocks for ambitious user interfaces
React-based component library
Alpine Electronics is an international enterprise specialising in car audio and navigation systems that are used by manufacturers such as BMW, Audi, Mercedes & many more. The company counts more than 13,000 employees and wanted to take their data management apps to the next level by utilising a React-based component library that can be composed in flexible ways.
To meet this challenge, a team of six frontend specialists was formed. My contribution was to gather requirements in on-site workshops, specification of features & component APIs, UX design, frontend development, code reviews and the definition of GraphQL APIs. A set of more than 150 components now provide the foundation for 20 apps and counting.
