Node.js telegram bot
I am very satisfied with the cooperation, first and foremost everything is professional.
Vitaliy did even more than I expected.
There was a lot of code written before him, but he figured everything out without asking again or clarifying.
It is evident that Vitaliy has extensive experience.
To be more precise, he completed the website written in next.js for me, added a PostgreSQL database, and made significant changes to the bot that was written in node.js.

Web platform for the establishment
Collaboration with this contractor left exclusively positive impressions. The person is open and accessible for communication, always ready to discuss all project nuances when necessary, and responds promptly to questions. During the work process, there were no difficulties, as a solution was immediately sought for any problematic moments.
It is especially important to note the flexibility in the approach to work – the contractor took into account all the client's wishes that were outlined, while also demonstrating creativity where the task was not fully developed. I do not regret having provided additional space for creativity, as the final product turned out to be at a higher level than previously expected. Overall, the collaboration was comfortable and effective, and I can confidently recommend this contractor to others.

everything is great - we will continue to work
An excellent programmer, just a find! The quality of work is top-notch and efficiency did not disappoint. Yes, a couple of times I had to point out minor details, but he fixed everything without unnecessary questions and with complete calmness. The work took a little longer than planned, but he was always in touch - never disappeared - so it was not a problem at all. He even took into account my small whims and implemented them perfectly. The result is beyond praise.
I am already preparing the next project!
