About

As a Data Scientist and Python Developer based in Warsaw, Poland, I have built a dynamic career in data science, leveraging tools like Python, IBM SPSS, and SQL to drive business analytics and data visualization. My journey began with a Bachelor's degree in Sociology from Warsaw University of Life Sciences, and I am currently pursuing a Master's degree in Computer Science at the University of Lodz. I thrive on transforming raw data into actionable insights and have gained valuable experience in various roles, including my current position as a Data Entry Assistant at 24betting. Here, I manage large datasets, conduct statistical analysis, and automate data processing tasks to support business decisions. Prior to this, I worked as a Data Analytics Trainee at Inet Install sp, where I gained hands-on experience with data analysis tools and worked on renewable energy projects. I also served as a Business Analytics Intern at Sensify Spain S.L., focusing on renewable energy data analysis and optimizing business processes in the banking sector. Fluent in Russian, Polish, Belarusian, and English, I effectively collaborate in diverse, multicultural environments. My certifications in Python and data science underscore my commitment to continuous learning and professional development.

Best back-end engineers I've ever worked with.

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly.”
