Hi there :)

I'm a software architect and developer with a focus on embedded systems and device development. The results of my work in this area are usually protected by exclusive rights of my clients, hence, you can only find pet projects, learning environments and similar things here on my account. Feel free, to check out my website for descriptions of my professional projects.

  • 🔭 My last project was the development of a smoke sensor
  • 🌱 I’m currently learning Rust and Zephyr OS
  • 👯 I’m looking to collaborate on embedded systems projects
  • 🌎 I'm located in Europe (right now in Germany)
  • 📫 Feel free to reach out to me via mail@int.winterstein.biz or on LinkedIn

Repositories

  • net-income-germany - Net income calculation regarding German social security and income tax laws.

  • tsp-http-client - Simple HTTP client for requesting timestamps from a timestamp authority (TSA) using the RFC 3161 standard.

Web Development

I created two themes for the static site engine Zola:

  • Project Portfolio - Extension of the Daisy theme to provide specific functionality for a project portfolio like my own website.

Habitica

For the open-source habit tracker Habitica I created a soft-work, that facilitates self-hosting by automatically creating Docker containers for each release. Additionally, I extended / replaced some functionality that is needed differently, when self-hosting compared to the hosted version. It can only be found on GitHub, because Habitica itself is developed over there.
