I am a trained computer scientist, having received my **Diplom Informatik** (equivalent to Master of Science in Computer Science) from [TU Dresden](https://inf.tu-dresden.de) in Feb 2022.

As most of online activities commonly happen under this pseudonym *schmittlauch* anyways, I decided to set up this overview without publicly revealing all my private information.
If this profile looks interesting to you or your company, I kindly ask you to **[contact me](./contact.html) for further information and discussions**.

### I am open for jobs that…

- …are **remote or in the Dresden area**:  
Being currently located in Dresden (Germany) I do not want to move right at the start of the job. So far I am not entirely sure which field I'd like to work in exactly and want to ensure a good fit between job, company, and me before condidering longer-term relactions. This might change over time.
- …involve at least some work **on and with Free and Open Source Software**:  
I am passionate about Free and Open Source software and would like to work not only with, but also on such open projects regularly on the job. This is a soft and flexible requirement, I do not expect all products to be Free Software. I do hope though to be able to contribute back to existing projects and communities, or be involved in new Open Source projects.
- …do **not involve work on** so-called **cryptocurrencies or Blockchain technology**.
