Data Analyst with a Master's in Information Systems offers online lessons in Computer Science, SQL, Python, Excel for students

I am a Data Analyst with 2+ years of professional experience and a Master's degree in Information Systems and Technologies from Kyiv Polytechnic Institute. I teach online in English or Ukrainian, for students, career changers and professionals who want practical computer science and data skills. How my lessons are structured: 1. Short goal check: at the start we agree on what you want to learn (exam preparation, a university project, a new job, or a specific tool). 2. Explanation in simple steps: I break each topic into small, clear parts with examples. 3. Hands-on practice: you write the SQL query, Python script or Excel formula yourself on real datasets, and I guide you as you go. 4. Review and homework: we sum up what you learned, and you get a short exercise to practise before the next lesson. What I can teach: - SQL: from first SELECT queries to joins, CTEs and window functions - Python for data analysis (pandas, numpy) and automating routine tasks - Excel and Power Query: formulas, pivot tables, automated reports - Data visualization and dashboards in Power BI and Tableau - Basics of statistics and how to interpret results - Help with university assignments and projects in computer science and data analysis In my work I built automated reports and dashboards and wrote Python scripts that cut manual data checks by 70-80%, so I can show you how these tools are used in real jobs, not only in theory.
