Data Scientist at Ipotekabank OTP Group who improved cash-loan scoring Gini from 0.50 to 0.55.

At Ipotekabank OTP Group, I introduced salary-based features into cash-loan application scoring, improving Gini from 0.50 to 0.55. My work also contributed to a 45% increase in monthly loan disbursements, alongside other business factors.

I’ve back-tested scoring models across mortgage, auto-loan, and micro/small-business products, and evaluated anti-fraud scoring performance. At Alif Uzbekistan, I developed a search-ranking model and conducted A/B testing for a new search system.
