I’m a Manual QA Engineer specializing in mobile app, web, and API testing, with hands-on experience across iOS/Android and web admin panels. I focus on functional, acceptance, regression, smoke, and exploratory testing, including UI/UX validation.

At Kidsup, I built the QA process from scratch—creating test documentation, checklists, and test cases—while writing bug reports and maintaining testing timelines. I tested payment integrations and APIs (Robokassa, YuKassa, Google/Apple), push notifications, and analytics (Mixpanel), and I run demos with the team and stakeholders.

Earlier at Humanforce, I validated REST APIs against specifications by checking requests and responses (JSON) against documentation. Using Charles Proxy, I mocked responses and verified error handling, and I worked with databases (AWS Database, Microsoft SQL Server) and feature flags.

I’ve also optimized regression coverage by updating the test scenario matrix and ensured reliable delivery within an Agile/Scrum workflow using Jira and Confluence. My work is driven by practical QA process improvements and reducing critical bugs after releases.
