Valeri did a good job getting our project started. The budget just wasn't available to continue. Since Valerie doesn't speak english, Google Translate does a good job, but it can be challenging to discuss very technical things.

The best cooperation and the best result I ever had . Valeri lead me through the hole process. He also made videos to make it easy to compare the setups and configuration. I will hire him again!

It was the first time i hired someone on freelancer and i had a good experience with Valeri. The project was complex and required to clearly define some interfaces between my software code and what valeri programmed. Valeri has a solid background in C programming and communication interfaces. The power electronic part of the project was a bit more difficult to handle and required more effort than expected. Be sure to clearly specify what you want and at least have an idea on how to implement it. In the End, the project is working exactly the way i wanted so I´m happy, that´s the most important thing. Thank you Valeri

I worked very hard to make sure he could perform the work required. He assured me he had the knowledge and skills. He promised to complete the project in 20 days for a certain amount. After 60 days I pressed him harder and offered to work closely with him to finish the work. At this time he indicated that he no longer wanted to work on the project. I've paid him about 50% of the agreed upon price with very little to show for it. I'm now left in the position of being way behind on my commitment, having less money to work with and an upset customer who wants his work done.
