I am a Certified Data Analyst with a Master's degree in Finance and Accounting mixed with Big Data from SGH Warsaw School of Economics, where I graduated with a perfect grade of 5.0. My technical skills encompass a broad range of tools and languages, including Python, SQL, PowerBI, and Bash, with proficiency in using libraries and frameworks such as Pandas, Numpy, Matplotlib, Seaborn, and PyTorch. I have hands-on experience with databases like Azure, T-SQL, and PostgreSQL, and I am well-versed in ETL processes and data visualization techniques. My interests lie in Deep Learning, Machine Learning, Exploratory Data Analysis, and Big Data, which I have continuously developed through various courses and certifications. In my current role as a Data Analyst at XTB S.A., I specialize in data analysis within the trading department, focusing on model transactional data. I generate reports from extensive business and market datasets, optimize efficiency through automation using procedures and APIs, and collaborate closely with the data warehouse team to create impactful PowerBI dashboards. My responsibilities also include developing and maintaining a Flask-based web application for efficient database access and data export, as well as creating stored procedures for data deviation reports. Through these projects, I have honed my skills in web app development, SQL databases, data processing, and visualization, enabling me to provide comprehensive insights and support data-driven financial decisions.Tech Stack
