What I'm looking for

I’m looking to deliver reliable software quality by combining manual testing, UI/API automation, and performance testing. I want to work in Agile teams with strong collaboration, clear requirements, and continuous improvement in QA.

I’m a Senior Full-Stack Tester with 6+ years of experience validating quality across web, mobile, fintech, and blockchain platforms. I combine manual testing discipline with automation skills to deliver reliable releases in fast-moving teams.

I’m hands-on with UI and API test automation using Playwright, WebdriverIO, Robot Framework, and Pytest, and I also run performance testing with JMeter. I focus on API validation (Postman, SQL), building end-to-end test strategies, and managing defects through the full lifecycle.

Across Agile Scrum and Waterfall projects, I collaborate closely with developers, product owners, designers, and cross-functional stakeholders to align on requirements and deliverables. I design, review, and maintain detailed test cases and documentation, and I track progress through structured reporting in Jira and Confluence.

In my recent work, I’ve automated regression coverage to reduce testing effort and supported SEO-related validations, including phishing SEO site testing. I’m committed to continuous improvement in QA processes—staying proactive under pressure and adopting new technologies to raise quality.
