QA Engineer with 4+ years of experience testing Web3, AI, mobile, and web applications. I specialize in exploratory, functional, regression, smoke, usability, and API testing. I've worked with startups to identify critical bugs, improve user experience, and validate fixes before release. My portfolio includes real-world QA case studies, independent product reviews, and structured bug reports across Web3 and SaaS products. I'm currently open to remote QA opportunities and freelance testing projects.
