Eva Koskova

I’m a proactive Data Analyst & BI developer with 5 years in BigTech, using analytics to surface tactical insights and measurable business impact. At my current Sport analytics international company, I analyze football metrics for Japanese leagues, benchmarking teams and delivering scouting insights that directly support transfer decisions. I communicate findings to external clubs and build reusable Power BI assets—two BI templates adopted by 200+ professional clubs and a seven-episode “how-to” video series.

Previously at OZON TECH, I worked in a product team of 30 analysts on customer service analytics and dashboards for C-level leadership. I built a single data warehouse feeding 100+ panels and enabled 6K employees to update critical dashboards regularly, including an emergency dashboard and alerting system for money loss events. I also improved support efficiency by 30% through a Quality Control report, reduced costs by automating customer support KPIs, and increased dashboard usability by 20% using a universal design code, leveraging SQL (BigQuery, Vertica, ClickHouse, PostgreSQL), Python, and BI tools like Power BI, Superset, and Grafana.
