    Stamatis was fabulous to work with and I will certainly hire him again if a suitable task comes up. He spent an hour going over the details of a 2 hour job and then didn't charge me for that. So after completing the job I gave him an hour bonus. He went out of his way to complete the task in an earlier time frame in order to fit into my tight schedule on the project. He know his work and did an excellent job, even on the collaboration with the other part of my team. Awesome experience!
