Still Winner
@stillwinner
I lead end-to-end QA for Web and Web3 financial platforms, strengthening release readiness and product stability.
UkraineWhat I'm looking for
At NEAR DevHub, I own end-to-end QA for Web3 financial platforms including Nearn, NEAR Treasury, and Trezu, covering payments, stake delegation, voting, and multi-token workflows.
I independently design test strategies, plans, risk assessments, and release quality gates. I've created and executed 200+ test cases, reported and tracked 700+ high- and medium-severity bugs, and validate backend and API behavior with Postman, DevTools, and documented schemas.
Previously at Exsportia LTD, I tested web and mobile applications across multiple releases, authored 300+ test cases, and tracked 1,000+ bugs affecting core user flows. I also tested iOS and Android apps, Hebrew RTL localization, and mobile network traffic.
I work comfortably in remote, cross-functional teams and use Jira, GitHub Actions, Docker, Sentry, PostHog, Playwright, and AI-assisted QA scripting to support reliable releases.
