What I'm looking for

I’m looking for a remote team where I can own QA strategy and test architecture, build reliable automation (Cypress/Playwright), and apply AI-assisted QA (Claude tools, MCP) to improve coverage and quality gates.

I’m a Senior QA Engineer with 8+ years of hands-on experience in full-cycle testing of web and API applications across AdTech, Data Analytics, and real-estate domains. I advanced from Junior to Senior within the same company, growing from feature testing into owning test architecture, QA strategy, and our team’s automation framework across multiple products.

In my current role at CloudGeometry, I lead ongoing improvements to our automation framework, maintain reliable E2E automation in Cypress (primary) and Playwright (support), and integrate suites into CI/CD with Jenkins and GitHub Actions. I also work daily on AI-assisted QA—using Claude Code and the Claude API, applying Model Context Protocol (MCP), and even designed and deployed an AI-powered Gherkin test-case generator on AWS (Databricks) to reduce manual test creation, while still providing QA sign-off on staging builds.
