About

Turning raw data into decisions — from SQL data models and A/B tests to applied statistics and machine-learning projects. I validate analyses against references and cover them with tests.

Open to Data Analyst opportunities B.Sc. in Engineering Physics, Faculty of Physics — Southern Federal University (SFEDU), expected 2027 Focus areas: A/B testing & statistics, SQL / business analysis, applied ML (computer vision) Tech stack

Focus: A/B testing & statistical inference · SQL & data modeling · dashboards & data visualization · applied ML · systems analysis (BPMN, REST API)

Featured projects

A/B Testing Statistical Significance Platform — self-contained toolkit for designing, analysing and early-stopping online experiments: sequential testing (SPRT, mSPRT, Pocock / O'Brien-Fleming), power analysis, confidence intervals — validated against published references with 42 tests. Python · SciPy · statsmodels · Streamlit · SQLite — Live demo · Code

Credit Application Analysis — business-process analysis for a credit-application system: BPMN diagram, functional requirements, REST API specification, SQL queries and a SQLite database. Systems analysis · SQL · SQLite · BPMN · REST API

YOLOv8 Vest Detection — computer-vision system that detects safety vests on workers. YOLOv8n trained on 1413 images, mAP50 = 0.732, with a Streamlit web demo. Python · PyTorch · YOLOv8 · Streamlit · Matplotlib
