Data Analyst

I am a Data Analyst with 5 years of experience in FinTech, Banking, Payments, and regulatory analytics. I focus on turning complex data, business logic, and ETL flows into clear insights that help teams make faster and more reliable decisions.

I have built a data quality monitoring system from scratch, including 30+ PostgreSQL checks, and have helped resolve more than 500 enterprise DWH incidents. My work has supported accurate reporting across 10+ payment systems and improved the reliability of financial and regulatory data.

In my recent roles, I audited reporting data marts, documented logic for knowledge transfer, and created reusable SQL templates that reduced recurring analytics request processing time. I also worked on migration-related data quality validation and built reconciliation dashboards for management and cross-functional teams.

Earlier, I monitored enterprise DWH data quality across transactional, client, and payment data, analyzed ETL anomalies, and standardized incident handling from detection to closure. I also automated recurring SQL checks and dashboard uploads to eliminate manual validation work.

At QIWI, I reconciled financial data across multiple payment systems and improved reporting accuracy for compliance and audit purposes. I also automated SQL and Excel reports, reducing manual effort and speeding up reporting cycles.

I hold a Bachelor’s Degree in Electronics Engineering from Moscow Aviation Institute and have completed corporate training in PostgreSQL and PL/SQL. My core strengths include SQL, Python, data validation, reporting automation, data warehousing, and cross-functional collaboration.
