    “The work process has been really nice with Yang. He took over an previously rough and problematic job, got quickly into it and became a strong problem solver. Additionally, he did go above and beyond of what was asked. Late night work and almost 24/7 reachability were just two of his strengths. The communication was very good. Basically, I gave him the tasks, he organised everything, and from there on I just had to wait until the job was finished. I can really recommend Yang for future projects - especially, if a "fireman" is needed. [13 March, 2018] I highly recommend him. He managed to finish project from A to Z, including overcoming many issue on the way. Big thanks again and Im looking forward working on with him in the future!”
