    “Worker was very difficult to work with. When the Bid was submitted, he wrote in perfect English (and has his location as Texas, USA). Once the bid was accepted, he no longer wrote in anything close to understandable English. I believe he had someone typing for him at the time the bid was submitted. Once work got underway, the worker kept asking for more money to do what was in the specs because he misunderstood the specs. The work took too long, and several parts of the code I practically had to write myself because the worker was not proficient enough to figure it out himself. The code was submitted multiple times without testing by him first, resulting in tons of lost time back and forth repeating the same bug reports over and over. I will not work with this worker again.”
