About Me

A brief look into my testing background and engineering philosophy

Quality Assurance Specialist

With hands-on experience in executing functional, regression, and end-to-end testing across web and mobile ecosystems (Android & iOS), I bridge the gap between development speed and code quality.

Having worked at TestMu AI (formerly LambdaTest) and currently driving quality engineering at TCS, I understand the scale, complexity, and tooling needed to run reliable test automation. I focus on building efficient test solutions, writing maintainable OOPs-based automation scripts, and driving Agile methodologies.
