Profile
Data Analyst / Junior Data Scientist with a strong quantitative background in mathematics,
econometrics, and applied data analysis. Currently pursuing a Master’s degree in Mathemati-
cal and Statistical Methods in Economics at Masaryk University. Experienced in SQL, Python,
and exploratory data analysis through academic and project-based work. Interested in pre-
dictive modeling, risk-related analytics, and translating analytical findings into clear business
conclusions.

Technical Skills
Programming and Querying: Python, SQL (PostgreSQL), R
Python Libraries: pandas, NumPy, scikit-learn, matplotlib
Data Analysis: exploratory data analysis, data cleaning, feature analysis, descriptive statis-
tics, data validation, model evaluation
Databases and Data Workflows: SQL querying, joins, aggregations, structured reporting,
working with relational data
Machine Learning: regression, classification basics, model comparison, introductory predic-
tive modeling
Other Tools: MS Excel (advanced), Git, Power BI, REST API basics, AI tools for analytical
and research workflows

Selected Projects
Traffic Flow Forecasting (Bachelor Thesis)
Built multi-horizon forecasting models (h = 1–24) using SARIMA/SARIMAX on real-world
traffic data from the UTD-19 dataset.

• Performed exploratory analysis and preprocessing of large hourly time-series datasets from
urban traffic sensors
• Implemented data cleaning, missing-value handling, and model preparation workflows
• Built and compared forecasting models using quantitative evaluation metrics
• Interpreted model outputs and summarized results in a structured analytical form

Consumer Behavior Prediction (Econometrics Project)
Developed regression-based models to analyze factors associated with purchasing decisions.

• Applied OLS and diagnostic testing to structured economic data
• Evaluated model assumptions, coefficient significance, and overall model performance
• Translated statistical results into practical analytical conclusions

Dashboard Development (Power BI)
Designed interactive dashboards for monitoring and visualizing economic indicators.

• Prepared and transformed data for reporting and dashboarding
• Built KPI-oriented dashboards to support structured interpretation of data

Credit Card Customer Clustering using Machine Learning Methods
Applied unsupervised machine learning methods to segment credit card customers based on
behavioral and financial usage patterns.

• Performed data cleaning, preprocessing, and exploratory data analysis on structured cus-
tomer data
• Used Python libraries such as pandas, NumPy, and scikit-learn for clustering workflows
• Analyzed customer groups based on spending, balance, cash advance, and usage frequency
variables
• Interpreted clustering results from a business perspective and identified meaningful customer
segments

Planar Data Classification Models (Neural Networks)
Built and evaluated neural-network-based classification models on planar datasets as part of
machine learning training.

• Implemented and tested classification models in Python
• Compared model behavior and decision boundaries across different approaches
• Worked with feature spaces, classification logic, and model performance evaluation
• Strengthened practical understanding of supervised machine learning workflows

Regression Models: Estimation of Production Functions of Different Countries’
Economies
Estimated and compared regression-based production function models for selected countries
using macroeconomic data.

• Applied econometric modeling techniques to analyze relationships between output and pro-
duction inputs
• Performed parameter estimation, model comparison, and interpretation of results
• Worked with structured economic datasets and statistical inference
• Summarized findings in a clear analytical form
