It was necessary to write a script that analyzes large calls in CSV files. Nikolai proposed the best deadlines for execution until the end of the day and fulfilled the promised, in addition, on my request, introduced the necessary changes to the script. The script works properly.

Great work. Term and quality at the highest level.
thank you

Great work. constantly in contact. Requirements were made within a reasonable framework. I recommend it.

Communication is great, everything is done in time, I recommend

The main advantages of freelancer personally from my position:
1) don't rush to close the project faster, but calmly leads the work to the end and introduces all the necessary directions
In difficult situations, it offers the optimal solution, demonstrates initiative
3) Always in contact
In general, the impression of cooperation is only positive. The project was large and work-to-work. However, the developer did not disappear, did not kill, but was doing his work calmly. And that gave its result.
Thank you for work. I recommend cooperation.

There was a delay in time because the site was much more difficult than it seemed at first sight. A lot of work has been done to test and explore all possible features of the site. The execution patiently and methodically moved to the finish from day to day and achieved success! A labor-friendly and responsible freelancer to whom you can trust the performance of even very difficult tasks in its specialization. I recommend cooperation!

It’s not the first time I work with the executive, the task is done.

Everything is great. The task is performed quickly. I hope for further cooperation.

Nicholas made the necessary tz without questions in the way I wanted!
