"Josef provided very good insight during our session. He was able to identify problems which I were not aware of, and suggested ways I could overcome those problems. He was also eager to point out things which would help me in my learning journey. Most importantly, he did his best to instill confidence within myself. I would definitely recommend Josef to anyone having difficulties finding their way around a difficult project. He has extensive knowledge and experience, not only in backend development, but software engineering in general. "
