What I'm looking for

I’m looking for remote opportunities where I can grow in QA and develop my automation testing skills.

At Yandex Practicum, I completed the testing cycle for Yandex Samokat, analyzing requirements, preparing test cases and checklists, and performing functional and regression testing across web and mobile applications. I also tested its REST API with Postman and checked server requests and responses.

Across projects including YandexRoutes, YandexMetro, and YandexDrive, I tested interfaces and mobile applications, designed API tests, and reported defects. I’m looking to grow in QA by developing my automation testing skills, and I’m open to remote opportunities.
