With more than 10 years of experience with web apps, I can help you build ambitious web experiences with a first-class user experience. I’m specialised in developing with React.
ServicesMillions of setlists at your finger tips
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.
setlist.fm“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!”

At the speed of light
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.

Küchenfinder is an Austrian platform operated by Molindo, which helps you to purchase a new kitchen. About 6 million users visit the site per year to leverage a data-driven search engine to connect with qualified experts.
I developed multiple React apps for the platform, covering a kitchen configurator for customers, an app for experts to manage customer inquiries and one for admins to configure core data. Further to this, I developed a GraphQL API in Node.js which provides clients with performant access to distributed data from REST micro services.
