Quickly, qualitatively, will help understand the functionality and overall a pleasant person, definitely 10 out of 10

Working with Yury was an excellent experience. He developed a complete backend for a mobile game using Express.js and Firebase Firestore with a very clean MVC architecture. The code is professionally written, well-documented with comprehensive API examples, and all endpoints work exactly as specified. I'm particularly impressed by his attention to detail - proper error handling, logical folder structure, and readable code. Additionally, he provided detailed documentation with request and response examples, which greatly facilitates further project development. The programmer met all deadlines and demonstrated excellent communication skills throughout the project. I will definitely use his services for future projects without hesitation.

I would also note that Yuri joined an existing project, quickly set it up locally, figured everything out, and uploaded the changes himself. I would be happy to continue with new tasks.

The work was done quickly, professionally, and with high quality. I recommend for collaboration!

Very well done execution of the order

Everything is of high quality, a very professional person. I recommend.

Everything we agreed upon has been done.

As always, everything is done excellently.

Yuri's skills and professionalism in working with JS exceeded all my expectations.

I want to express my gratitude to Yuri for the excellent work on our project. Throughout the collaboration, he demonstrated high competence, a deep understanding of JavaScript, and unparalleled attention to detail.

Yuri did an excellent job developing complex functional modules, using modern approaches and best practices in JavaScript. The code was written cleanly, structured, and documented, which significantly facilitated the review process and further maintenance.

I recommend him for any projects requiring a high level of knowledge and experience in JavaScript.

Overall satisfied with cooperation with this contractor. A good specialist in terms of technical skills and ability to work within a specified deadline. The quality of work was generally satisfactory, with the only drawback being perhaps carelessness, but this is compensated by the final result, loyalty to the customer, and timely project delivery. Ready to work again, so I can recommend Yuri as a competent professional.

Good developer. Fast. Recommend

Fully satisfied with the work. Quickly and qualitatively done everything.

The project is done according to tz, a good executor, always in contact, doesn’t miss, knows his job! I am pleased with work!

Very fast, very professional. pleasant to communicate. I was pleased with the work with the executive. I recommend it 🙂

It is done in time and according to agreements.

Very pleased with cooperation.
Everything is done accurately according to TZ.
There was no need to make a straight that was a great rarity by experience.
Thank you very much to Yuri.

Yuri has done his job well, I can imagine working with him again. The project was conducted longer than agreed, but the deadlines were not critical in the project.

The advantages:
He performed the work well.
All the gods fixed silence.
-I want to note the willingness to discuss video connection requirements, this allows you to save a great amount of time and discuss details more deeply.

The Disadvantages:
The artist hopes on his memory instead of making notes.
Not very attentive to the details, if they are many.

I wish Yuri success in the next work!

High professionalism, pleasant constructive communication.
Everything in time and quality.

Everything is super! As always! Yuri on the link, everything is clear. Thank you !

There were small problems with the implementation of one JS function, but this is rather due to the characteristics of this function itself.
The project is implemented.

Дякую за докладні консультації та корисні поради!

Спасибо за работу выполненную на сайте.

Спасибо Юрию, за то что помог осуществить правки в проекте. Сделано очень быстро.

Unlike many freelancers, Yuri first acquainted with the introductory description of the project and the documentation and the discussion has already gone on the essence, not on an empty place.
Immediately offered the necessary technology, which confirmed the competence
[+] Implementation of the project without loading the questions, the answers to which are in the documentation
The code has become readable, clean (as it allows to judge the competence of the participant with a different range of technologies)
Completely gentle, mostly - responded quickly
[-] It is desirable to introduce quality control before giving up the work: in the process of taking the work several times small bugs and failures were found. This adds time due to the re-check of each “build”, communication. But Yuri removed everything, thank you!
A little out of time. But partly our fault - a couple of errors were found, they were removed.

Thank you Yuri for your collaboration, the project has been completed!
