Google BigQuery

I use Google BigQuery as a productive and reliable data warehouse for all our non-personalized data. It is accessible from anywhere in the world and can be easily queried and analyzed using Looker.


I utilize numerous Python scripts to extract data from internal sources. These scripts are run on a dedicated internal server operating Debian Linux, enabling efficient data retrieval and processing.


SQL is a significant part of my work because it is needed both for querying internal databases and as a native language inside BigQuery.

Looker Studio

I have developed several useful dashboards that display the current state of our business.

About me

As a mathematician, I take great pride in my diligent work with numbers and data, uncovering intricate patterns. With a dedicated focus on formulating and rigorously testing hypotheses, I utilize Python programming and the powerful BigQuery warehouse. My sincere goal is to advance my career in the fields of Data Science and Machine Learning, continuously enhancing my skills and expertise. I am committed to staying current with industry advancements, striving for excellence in all endeavors.
