I’m a QA Engineer with more than 3 years of experience testing web and mobile applications, microservice architectures, REST API, and integrations with external systems. I began with frontend testing of a CRM system (90% UI/UX) and then fully moved into backend and integration testing (80% API / 20% mobile), staying close to requirements and proactively finding risks before development.

At Wildberries, I test critical order, supply, and notification flows across async scenarios in Kafka, including idempotency and duplicate handling, and I validate API behavior via Postman/Swagger (status transitions, validation rules, conflict cases like 409). I also improved CI/CD quality in GitLab Actions, monitored failures with Kibana, and used Charles Proxy to reproduce real-world network issues—finding a critical double-billing bug and driving backend idempotency plus frontend button blocking. In DNS, I grew from Junior to Middle on the same project through cross-team collaboration, UI checks against Figma, and targeted regression of key acceptance scenarios.
