About me
Hi, I'm Sergei, a data analyst with a degree in economics and years of experience running my own business, so I focus on what your numbers mean for decisions, not just charts. I hold Google Data Analytics, Advanced Data Analytics, and Business Intelligence certificates. I work with SQL (BigQuery), Python (pandas, scikit-learn), Excel, Google Sheets, Tableau, and Looker Studio. You get clean data, clear findings, and a short written summary you can act on. Message me before ordering and I'll confirm scope and timing.
