New waters ahead!

I'm currently exploring opportunities for 2024.

Always change a running System. Nuxt2 to Nuxt3

As Vue2 approached its end of support on 12/23, we were compelled to upgrade to Nuxt3. Although we refactored parts of the codebase to improve it and eliminate a significant amount of technical debt, this was still the largest project I've worked on, with the primary objective of ensuring that there were no discernible changes for the end customer


Performance is key

This was not a typical project with a clear beginning and end, but rather an ongoing and engaging initiative to monitor the page and implement performance optimizations whenever viable and appropriate.


Individual Shipping requires a custom checkout

It's an absolute necessity for e-commerce to have fast and reliable shipping. To match the custom shipping options of CandleScience I helped to design and implement a checkout flow that is tailored to their needs.


Accessible E-Commerce

After an comprehensive accessibility audit from an external agency I helped CandleScience to implement the necessary changes to make their e-commerce accessible.


Applying a new design for a running e-commerce

I helped CandleScience to implement a redesign from scratch. For long-term maintainability I introduced the concept of a small scale design system and self-contained components to establish a coherent user experience with low maintenance effort.

Bridging the Gap between Design and Development

Fielmann already had a design system that was entirely focused on designers. I helped them to make the design system consumable for developers. This mainly included implementing the existing design patterns into code and distributing them in a different granularity. I was the Design Systems Team Lead.

Prototyping a Real time experience

As the only technical person in a design team I set up prototypes with novel technologies to resolve risks at an early stage and help to communicate with something tangible.

Implementing a mobile experience

I helped brandeins to implement their planned redesign to create a consistent responsive user experience.

Cynefin® FOUNDATIONS online course

I often felt misplaced when running scrum on the inside but having a fixed scope and deadline on the outside. This plus an overconsumption of Dave Snowden videos on YouTube made me invest in an online course of Cognitive Edge. The lessons learned in this course stick with me ever since.

Establish a UI-Library

As part of a small informal group of people we managed to establish a UI component library to tackle the immense consistency problems Jimdo was struggling with. This felt great as it started as a grassroots project but ended up as something valuable and recognized throughout the whole company.


Build templates and the template interaction interface

As part of the so-called template-team I built website templates but also the user-facing CMS interface to select and adjust a template as needed. I worked as a designer, frontend developer and partially product owner.
