Johan Walles is a Lead Developer at Spotify. He possess expertise in android, debugging, java, eclipse, junit and 38 more skills. He is proficient in English. Colleagues describe him as "I worked with Johan for almost 2 years and I can honestly say he is one of the best engineers I’ve ever collaborated with. His technical expertise, matched by his unwavering discipline and commitment, while impressive it tells only half the story. The other half is one of child-like curiosity, passion, integrity, humbleness and a great sense of humour. This is the easiest recommendation I’ve ever had to give. I hope I’ll get a chance to work with him again." and "Johan is one of those rare diamonds you meet just a few times in your whole career. A true engineer that doesn’t shy away from any new challenges, that is language agnostic, that is a true champion of collaborative development, that shares his great knowledge not only when asked to but sets up learning sessions when he sees the need in the organisation. Just outside the very core of engineering he is also a great speaker that can explain complex matter to anyone in a company. He is humble, friendly, loyal and not the least - business minded. I highly recommend Johan and I would be thrilled to work with him again."
