At Sushisell, I built end-to-end analytics infrastructure by connecting CRM, Google Sheets, and internal systems through APIs and automated Python ETL pipelines. I designed PostgreSQL and ClickHouse data marts for revenue, marketing, and unit economics reporting.

I developed marketing and branch-performance metrics, including attribution, CPA, CAC, ROMI, sales funnels, cohorts, and retention. My Yandex DataLens dashboards and automated reporting replaced manual Excel reports, reducing manual reporting effort by more than 70%.

On a project-based assignment at TSS, I automated marketing and operational reporting in Power BI, reducing manual reporting time by about 40%. I also automated Python data preparation, cutting processing time from hours to 30–40 minutes.

Earlier, I analyzed financial products, customers, and marketing performance at Infinbank and Kapitalbank, and marketplace performance at XWAY and B2Basket. At NAFI Analytical Center, I supported research through public-source analysis, reports, and expert interviews.
