Education & Experience

Resume

Senior JavaScript Engineer

Freelance | Cologne, Germany

since 01/2022

After all these stations and the foundation of Mülheim Modular it was clear to me that I would like to work and structure freelance in the future. My focus is clearly on projects in the areas of JavaScript, TypeScript, React, Next.js and Serverless infrastructures.

Co-Founder

Mülheim Modular | Cologne, Germany

since 05/2021

In addition to the operation of our store, I can freely decide here which technology to use. To keep running costs low but offer maximum performance and stability we are currently developing our store system with modern SaaS products and a serverless infrastructure. As a CMS solution, we therefore rely on Shopify & Sanity.io to populate cutting-edge Next.js applications, which are deployed to the Edge via Vercel. Supporting applications, such as service bots or internal infrastructure will additionally be hosted in our Kubernetes cluster.

Senior Javascript Developer

TWT Interactive GmbH | Düsseldorf, Germany

10/2020 - 10/2021

Beyond my work as a developer, I supported decision-making processes regarding infrastructure and technologies, as well as colleagues in the use of Typescript. The support and further development of a model-driven React frontend was my primary task here. Besides this task, I also supported the development of a UI library for a market-leading customer in the sanitary industry.

Frontend Developer

Ambient Innovation GmbH | Cologne, Germany

09/2018 - 09/2020

In this job, I was in the lead role of the front-end developer of our Scrum team. Besides the responsibility and development of the frontend, user flow tests with cypress were part of my daily tasks. I also supervised a practical project at the University of Cologne and supported the students in the realization of their project.

Frontend Developer

d-SIRE GmbH & Co. KG | Cologne, Germany

10/2016 - 08/2018

My focus here was, among other things, the planning & implementation of modern frontends according to the Atomic Design Principle. With the help of Patternlab I was significantly involved in the implementation of a frontend library for Europe's largest perfumery. This was followed by the development of a configurator application under AngularJS for one of the leading DIY stores.

Web Developer

Möbel Concept | Euskirchen, Germany

02/2016 - 09/2016

The implementation of a modern frontend using modern web technologies and Ajax support was one of my primary tasks. Apart from that I was also involved in infrastructural topics like backup strategies or deployments.

Systems Engineer [Training]

Intro GmbH & Co. KG | Cologne, Germany

08/2013 - 01/2016

Among other things, I was responsible for the planning, commissioning and coordination of external service providers for a relocation. My daily tasks also included the support of the company's own Debian server landscape for Apache, MySQL, PHP, Varnish & File-Sharing applications.

Web Development [Traineeship]

Intro GmbH & Co. KG | Cologne, Germany

10/2012 - 07/2013

I supported during the relaunch of intro.de and festivalguide.de. Besides smaller tasks, the development of a dashboard for monitoring social media metrics was my primary project.
