Nikolay’s team has been phenomenal to work with over the past few months. They were able to put together some wonderful insights, reports, and Tableau dashboards for our management teams across various departments. We look forward to working with Nikolay’s team in the future on additional data science and analysis projects.

Nick Lowry

Chief Growth Officer, Wing Telecom

It’s been a pleasure working with Nikolay. At the very first stage of cooperation, Nikolay thoroughly studied the goals and already existing approaches, and tools applied to in-game analytics at our company. Next, he advised us to change the old ways, this decision resulted in increased efficiency in building reports and saved much of our time. Nikolay also offered to use a set of classification models written in Python for prediction tasks.
As a result of cooperation with Nikolay, the numbers in our company look way more transparent, now, when data is updated on a regular basis we can spend less time on creating reports. I would highly recommend his expertise and skills for future cooperation.

Working side by side with the Valiotti Analytics team we have outsourced our analytics department. Nikolay was our mentor and the focal point for this project. He gained insight into the company’s KPIs rather quickly and delegated part of the mission to his colleagues while working on the other one.
Nikolay’s team helped us with various components of analytics, namely they updated the Amplitude ETL to MySQL, improved the integration with GTM and Enhanced Ecommerce. Nikolay delved deeply into the tasks and actively communicated with our team.
We’re happy we could collaborate with a company having high expertise in this field as if it was our own in-house analytics team.

It doesn’t take long for Nikolay and his team to understand the problem. We held a couple of phone meetings, where discussed the company’s requirements for data sources and analytics
Working together, they helped us to build end-to-end reporting. The figures make much more sense now, and we can efficiently manage our advertising costs by tracking their flow.

It has been a pleasure working with Nikolai. First off, he tries to learn about the project in great detail to understand its needs. Secondly, the terms arranged in advance are almost always met, if there are no pitfalls along the way. And thirdly, you can come up to Nikolai with an idea and he knows how to turn it into a real project. That’s my best bet!
