At Fintexa, I built and maintained Playwright and TypeScript frameworks for payment and credit approval flows, reducing flaky tests by about 40%. I also integrated regression suites into Azure DevOps Pipelines.

At UPEX, I developed Playwright and Selenium automation frameworks for UI and API testing. I tested Web3 Dapps, wallets, and blockchain transactions, and validated backend logic with SQL.

As a Freelance Software Tester with uTest, I tested E-commerce projects built with Shopify and Magento, documenting bugs and validating shopping flows. At With Ela Studio, I developed and maintained websites and conducted QA testing; the testing plan I implemented contributed to a 30% performance improvement.

I’ve also built projects including a Cypress and Cucumber framework for OpenCart and a mobile automation framework using WebdriverIO and Appium. My work spans web, API, backend, and mobile testing.
