About Nikolay Efimov

I finished studying data analysis in a practical Yandex course. As part of the course, I learned Python and libraries (Pandas, Matplotlib, NumPy, Seaborn), SQL (PostgreSQL), gained basic knowledge of statistics and probability theory, A/B testing, cohort analysis and data visualization (Tableau). I also worked as a Head of the technological department of a large machine-building factory. Working in this position for 2 years, I mastered Excel (pivot tables, data aggregation) well, explored how to make presentations and reports. These skills helped me to identify points of growth and improvements in production in a large array of data and reduce costs by $ 400,000. I also gained invaluable experience in communication with colleagues and soft skills: formulation and prioritization of tasks, critical approach to algorithm for solving problems and the results obtained, planning project work.
