Personal preferences:

project duration should be a minimum of 3 months or more
preferably up to 5 days a week (40 hours)
commuting within the Cologne/Düsseldorf area is fine, but remote work is preferred
a mix between remote and on-site work is fine (for example, 2 days per week on-site)

Please get in touch with me to talk about project details. In case the project sounds promising I am willing to adjust my preferences.
