Project History
PyStrava
https://github.com/wefner/pystravaPyStrava helps developers create third-party integrations in Python with transparent authentication. At the same time, it still benefits from all the stravalib features. The major advantage is that one can use this library as a service without manual re-login.
Ansible and Vagrant Course
https://github.com/wefner/ansible-vagrantThis project contains all the materials taught in a course I had the opportunity to give. It helps developers and system administrators to bootstrap a local environment for a faster development experience.
SpotifyLib
https://github.com/wefner/spotifylibA Python-based project which extends the community library Spotipy by authenticating to the API endpoint transparently so it can be used as a service while still using all the functionalities of Spotipy.
SlackSound
https://github.com/wefner/slacksoundThis Python-based project monitors a Slack channel for reactions to music YouTube links. The most thumbed-up link will be added to a Spotify playlist. It helps offices to keep ambient music democratically.
FootyLib
https://github.com/wefner/footyA Python-based project that scrapes the website https://footy.eu/ for all the upcoming matches and results.
This is helpful for creating calendar events and adding them to the players' agenda. The website lacked this functionality at the time.
