Eike Send
Backend developer @ ioki
Fabian is definitely a professional Android developer and I enjoyed working with him very much! He knows his way around Kotlin and Java just as much as working with HTTP REST APIs and much more. His proficiency in working with the Maplibre SDK (Mapbox fork) is much appreciated and if you ever need someone to build an app for you, he is your guy!
