[открыть контакты](см. выше в блоке «контактная информация») As a junior Data Analyst, I analyzed user activity in a gaming application,
concentrating on the onboarding funnel. I calculated key metrics such as
Telegram DAU, WAU, and retention rate to understand user engagement and the
Linkedin effectiveness of the onboarding process. Using tools like Google Sheets
and SQL, I tracked user progression through the funnel, from sign-up to
Dnipro, Ukraine first use, and identified bottlenecks that hindered user conversion. I also
segmented the data by activity types and user languages to gain deeper
insights into the user experience. The results helped optimize the
HARD SKILLS onboarding flow and improve user retention and engagement.

Advertising companies In the second part of the project, I focused on Unit Economics and
analysis product metrics to assess the financial viability and performance of the
Basics of Probability Theory gaming application. I calculated key metrics like stickiness (DAU/WAU
A/B Tests ratio), average age, and retention rates. Using cohort analysis, I identified

Bigquery across different months since their first activity. For data visualization, I
utilized tools like Tableau, Power BI, and Amplitude to create detailed
reports and dashboards that communicated insights effectively. These
TOOLS visualizations provided a clear view of product performance, supported
data-driven decision-making, and helped optimize engagement strategies,
Google Sheets user lifetime value (LTV), and revenue generation. The project resulted in
Power BI actionable insights that contributed to enhancing the product’s
