ABOUT ME
SDET with 8 years of experience
SDET with 8 years of experience

I want to be a Codementor to share my experience as an SDET specializing in JavaScript/TypeScript, with a strong focus on modern testing frameworks like Cypress and Playwright. I enjoy helping others build reliable, maintainable test automation, and I find it rewarding to guide developers through best practices in end-to-end testing, debugging, and CI integration. Codementor is a great platform to give back to the community while connecting with people who are eager to grow in their testing and QA careers.
