Katsiaryna Semashkevich

I’m a Lead QA Engineer with 10+ years of experience across manual testing for mobile, API, back-end, and Web products, plus 1 year of automation testing with TypeScript and Selenium WebDriver. I focus on turning testing into a reliable delivery engine: clear processes, fast feedback, and measurable quality outcomes.

In enterprise and fintech environments, I’ve set up QA processes from scratch, implemented test case management for transparency, and tightened collaboration with developers before deployments. I reduced QA cycle time by 10–15% through earlier verification, and I cut change requests and UAT feedback by 30% by analyzing requirements against business needs and maintaining daily client communication. I also optimized QA work with Claude Code to accelerate test case creation.

As a QA lead and manager, I’ve built and scaled teams (from 1 person to 10) by mentoring newcomers, leading interviews, and improving execution standards. I set up end-to-end test strategies, delivered QA dashboards for metrics visibility, and improved production stability (including an 80% reduction in production issues). Across healthcare mobile projects, I ran full-cycle mobile QA for Android and iOS, improved quality by 30%, and contributed through release management and code-review-based merge strategy support.
