Looking for a job

Ekaterina Naumovich

@ekaterinanaumovich

I prevent e-commerce defects early through API, integration, data, and mobile test automation.

What I'm looking for

I'm looking to continue improving high-load e-commerce products through Shift-Left testing, complex integration validation, production troubleshooting, and test automation with Python.

At AliExpress Russia, I test high-load marketplace systems processing over 1.5M orders monthly, reviewing requirements, API contracts, and ER models before development. I validate affiliate redirects, tracking, financial logic, asynchronous Kafka and RabbitMQ flows, and end-to-end UI-to-database data integrity.

I've reduced analytics failures from 163 to 15 through ClickHouse and Hive validation, localized production issues with Grafana, Kibana, and Charles Proxy, and helped increase conversion by 5x. I also built a Python and Appium mobile automation framework that reduced regression time from three hours to 15 minutes.

Previously on the Leroy Merlin project at Go-Digital, I designed loyalty-program test strategy, regression-tested 100+ API endpoints, built isolated Docker environments, and investigated caching, session, and performance issues across web and mobile products. I enjoy Shift-Left testing, complex integrations, and helping junior QA engineers grow through practical knowledge bases and test cases.
