What I'm looking for

I seek a product-focused data science role where I can apply ML and analytics to improve user conversion, run experiments, build automated data pipelines, and collaborate with cross-functional teams in a growth-oriented environment.

I am a data scientist with hands-on experience driving product improvements through analytics and automation. At Sberbank I automated log aggregation with SQL and built Tableau dashboards to track GMV, DAU/MAU, churn, retention and conversion metrics.

I focus on turning data into product outcomes: I increased user conversion by streamlining funnels, simplified UI flows, introduced prefilled fields via integrations, and ran A/B tests for new features. I also replaced bootstrap-based estimation with the delta method to improve statistical accuracy.

Previously I worked as a QA Engineer leading automation for a Mutual Investment Fund product, automating four functional subsystems end-to-end and reducing testing time from one month to 15 minutes while lowering defective builds. I automated UI testing with a device farm and helped scale tests for other teams.

I hold a Master’s-level computer science background and built a diploma project: a financial assistant using RAG, LSTM, GPT and Streamlit to predict stock movements and provide company and peer analysis. I mentor juniors, design testing and analytics processes, and deliver practical, measurable results.
