Uzbekistan

Message

At Telleqt, I test web and mobile apps across Web3, AI, and manufacturing, including blockchain analytics, a digital art marketplace, an AI content generation app, and a manufacturing management platform. I develop end-to-end automated tests and validate data and APIs using Python, Playwright, Robot Framework, and pytest.

I also configure Docker-based test environments and CI/CD pipelines, investigate issues with Chrome DevTools and Postman, and use AI-assisted tools to support test automation and debugging. Previously, I tested a high-load billing system at Bercut Ltd and payment-integrated web and mobile products at FBS Inc.
