At Software Mind, I designed and built a Playwright-based C#/.NET 8 framework used by 10 people across 3 teams. I integrated Appium and BrowserStack for mobile testing and created Azure DevOps pipelines to run tests and publish results.

I’ve also extended Selenium automation frameworks for travel-agent back-office systems, FOREX.com onboarding, mobile apps and other platforms. My work has included API and database validation, performance testing, and AI-assisted QA workflows using MCP and CLI tools.
