What I'm looking for

I'm looking to apply and further develop my data analysis skills in a dynamic professional environment, using Python, R, SQL, statistical modelling, and data-driven problem solving.

I built an end-to-end credit scoring and risk assessment project using Statlog German Credit Data, classifying applicants as good or bad credit risks.

I compared LDA, logistic regression, k-NN, cluster analysis, and dimensionality reduction techniques to create a decision-support tool for credit assessment.

For a board game store, I designed and implemented a relational SQL database supporting sales and rentals. I translated business questions into SQL queries for tournament rankings, monthly promotions, rental delays, and transaction-volume analysis.

I'm completing a Mathematics master's degree focused on statistics and data analysis, with a thesis on non-mixture regression models and parameter estimation. I'm eager to apply and further develop my Python, R, SQL, and analytical skills as a Data Analyst.
