Experience

Pystrava

https://github.com/wefner/pystrava

Pystrava provides transparent authentication for the Strava API. This library has been inspired by spotifylib, which uses a similar authentication flow. The idea is to use all stravalib features and methods while handling the authentication transparently by providing all required details.

Ansible and Vagrant Course

https://github.com/wefner/ansible-vagrant

I taught a course on how to automate and deploy distributed systems with Ansible and Vagrant.

This was helpful for developers and administrators to bootstrap a local environment before promoting it to production.

SpotifyLib

https://github.com/wefner/spotifylib

A 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/slacksound

This Python-based project monitors a Slack channel for reactions on music YouTube links. If a video has a thumbs-up reaction, it will try to find its title and add it to a Spotify playlist.

FootyLib

https://github.com/wefner/footy

A Python-based project that scrapes the website https://footy.eu/ for all the upcoming matches and results.

This is helpful for creating vCalendars and adding them to the players' agenda. The website lacked this functionality at the time.
