In 2013, I graduated with a BFA and took my first job as a Junior Graphic Designer at a small, boutique ad agency. While there, my Creative Director warned me to never let anyone find out I could code, because if I did I'd be stuck doing it forever. I ignored his warning; it turns out he was completely right, but I've never been happier. I currently work as a developer advocate on a wonderful team where I help people build web applications in React, design and maintain their UI component libraries, and desperately attempt to stop back-end devs from writing any more CSS.

Current maintainer of RollupJS. After finishing my PhD studying the mathematical properties of black holes, I decided to go for less substance from then on and follow my passion of becoming a professional software developer. For the last six years, I have been doing full-stack consulting work for various clients at TNG Technology Consulting GmbH. This includes a big focus on DevOps: tuning Node servers, tending to Kubernetes clusters and orchestrating CI/CD pipelines are an important part my work. During this time, I also stumbled upon RollupJS, and while I originally only wanted to push a few improvements to their dead code elimination algorithm, I ended up rewriting it from the ground up. And in the process, I accidentally became acting maintainer of that project :) Since 2017 I have been continuously working on further improving tree-shaking, adding code-splitting together with Guy Bedford, and many other things to make it a great tool not only for optimizing JavaScript libraries but also for advanced and custom build processes at big companies like Github, Bloomberg, Salesforce and many others.
