I’ve seen large enterprises. My heart is with small businesses though. 🧡
I’m available on-site in Stuttgart, Germany. The further you want me to travel the more remote the work has to be 😺
Companies I’ve worked with
During my training to Computer Science Expert with Subject Area of Software Development I worked with WirbelWild GbR on Calidario. The editor is built with Vanilla Web Components.
During my employment with jambit GmbH I've worked with RND – a nationwide press company – on their successful relaunch. As part of a team we worked with React here.
During my employment with Mercedes-Benz․io GmbH I've worked for the automotive company of the same name. Here I was working with different teams. My focus was often the eCommerce product. We worked with Angular.
Organisations I’ve worked with
In my spare time I contributed to the digital education tool LernTools by upgrading their implementation to Vue 3.
Services I offer
What can you expect when working with me?
Semantic Markup 🏡
To make the most of the websites and web apps, having semantic markup is the foundation. Everything else is built on top of it.
Clean Code 🧹
I have the expectation to deliver a quality that can be used years down the road. Therefore I’m following quality standards in my industry.
Accessibility ♿
Our society is getting older as we speak. Our software must support them if we want to serve these people.
Testing 🧪
Software can get complicated quickly. In order to not break what once worked an exhaustive test suite should pass.
DevOps 🧯
You own it, you run it. Even when you omit „the Cloud” for political reasons owning the product lifecycle from code editor to the server facing the Internet is doable.
Performance 🏎️
People are busy. Let’s not make them wait for our software to meet their needs.
Security 🔒
No oopsies if we can avoid it.
Sounds wonderful? Then let’s talk!
