Sergey Matrosov

Head of Web Marketing, Simple

Valiotti Analytics helped us build a new data pipeline from scratch, replacing legacy tools such as Pentaho IDE with modern ones. They suggested the implementation of a modern data warehouse architecture for analytics and tuned instances to work with software. They also reacted quickly and introduced a huge number of improvements in the data analysis structure of our company. Moreover, several useful analytic dashboards were built for us during the project. We appreciate their approach as they dove deeply into the crucial details and understood our business constraints to react to data failure immediately. In order to support the new data stack, the team helped us build a monitoring system for the data routine. We are very pleased to work with Valiotti Analytics.

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!


Alexander Dolmatov

Chief Marketing Officer, JustKids

Valiotti Analytics has wonderful people and professionals in their team. Our company required technical assistance in maintaining and developing the existing data warehouse. Data experts from Valiotti quickly grasped the essence of the project and since then the team has been the strongest support for our analytics department. Many tests have been successfully passed and no less awaits us ahead. We sincerely look forward to further collaboration with such an excellent team. Thanks very much!

Since about six months, Nikolay and his team are doing tremendous work for us. They’re sharp, professional, efficient, and excellent communicators. They managed to bring clarity in a very complex and chaotic environment, with a patient, yet ambitious pace. Nikolay is also very present when needed, but can rely on his strong team. I definetly recommend!


Léo Dubert

Co-founder | MentorShow, MentorShow

We’ve worked directly with Nikolay on multiple long and short-term projects. The results were outstanding! Nikolay and his team delivered fantastic results in a professional manner for a global SaaS company based in Europe with +800 employees. They possess technical skills that are extremely hard to find in the tech market today. Valiotti helped us build our global data platform to empower customer-facing analytics products that excelled. Documentations, code-quality and cross-communications were very professional. I’m looking forward to my next project with Nikolay and his team!


Eyas K.

Aircall Product Manager, Aircall

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

We are grateful to Valiotti for the prompt delivery of our internal analytical system based on Plotly Dash. Despite the complexity of the task and the high level of ambiguity, we were happy to work with a team that knows how to effectively break down a task into components and acknowledges the right priorities in the initial project stages.


Synergentic’s CEO, Synergetic

“Valiotti Analytics has integrated with our data science team to set up dashboards for business intelligence and monitoring, and they advised on the integration and processing of data from heterogeneous sources. This has enabled us to react much more quickly and appropriately to signals and to improve day-to-day operational outcomes.

We especially appreciate their robust approach to eliciting our requirements and iterating on these. At the same time, they understood our need to deploy intermediate solutions quickly. They always had an ace up their sleeve when it came to tackling any snags, such as handling inconsistencies and load time optimization.

We look forward to continue working with Valiotti Analytics”.

Nikolai Valiotti

Founder & Data Consultant,

Valiotti Analytics

  • Has been working in data analytics since 2009.
  • Defended a PhD thesis related to data science in economics.
  • Knows everything about modern data stack for data engineering and analytics.
  • Created various machine learning models in R and Python.
  • Almost graduated from Online Master of Science in Analytics at Georgia Tech.

Work experience

I have been working in data science and data analytics since 2009. At the beginning of my career, I worked for several large companies (Lenta, Yota, Ulmart, and Baltika) and then remotely for Tapcore/Airpush.

Data stack

During this time, I studied and worked with all kinds of databases and SQL notations: MSSQL, MySQL, PostgreSQL, Oracle, Redshift, Snowflake, Vertica, Clickhouse, BigQuery, Cloudera Impala, and others, as well as various analytics tools such as Tableau, Oracle BI, PowerBI, Redash, Mode, Looker, Metabase, and Superset. Thus, over those years I gained a very good insight into what a modern data stack looks like and how it works.

Scientific achievements

I have created various machine learning models in R and Python for classification, forecasting, regression, and solving clustering problems. Using all this knowledge, I defended my PhD thesis on the development of a neural network model for evaluating business indicators (an analogue of the model for analyzing interventions using ARIMA).

Status quo

As a result of my work experiences and educational path, in 2019, I founded Valiotti Analytics: a company that consults and creates analytics stacks for modern mobile and digital startups. In 2020 I had a burning desire to refresh the fundamentals of my education. Even though I am already a PhD, I applied for the Online Master of Science in Analytics (OMSA) programme at the Georgia Institute of Technology, and now I belong to the community with the bee mascot!
