About

Professional summary

I am a Manual QA Engineer with more than three years of hands-on experience testing high-traffic, real-time consumer platforms across web, mobile, and backend systems.

I specialize in full-cycle manual testing, including functional, regression, exploratory, smoke, integration, cross-browser, cross-platform, and API testing. I have tested systems built on more than 12 interdependent microservices and more than 40 API endpoints.

I have strong experience testing REST and gRPC APIs with Postman and Swagger, including environment configuration and pre-request and post-request JavaScript scripting. I also validate backend data using PostgreSQL and DBeaver and analyze application logs with Kibana.

My mobile testing experience covers iOS and Android devices, emulators, Android Studio, Xcode, and ADB. I use Charles Proxy and Proxyman for network traffic analysis, response rewriting, throttling, and offline scenario validation.

I work effectively in Agile environments, including Scrum and Kanban, and collaborate closely with developers, product managers, and DevOps teams. I contribute to requirements analysis, test planning, defect investigation, sprint activities, and release validation.

I am focused on identifying risks early, producing clear defect reports, and helping teams deliver reliable and user-friendly products at scale.
