Are you looking to eliminate critical bugs before your users find them? Need a QA Engineer who doesn’t just run tests, but actually thinks like an end-user to secure your product’s quality? With over 4 years of hands-on experience in Manual and Automation testing, I specialize in shipping bug-free Web, Mobile, and Crypto/Blockchain applications. Whether you need structured test cases or rigorous exploratory testing, I’ve got you covered. 𝗜 𝗱𝗼𝗻'𝘁 𝗷𝘂𝘀𝘁 𝗲𝘅𝗲𝗰𝘂𝘁𝗲 𝘁𝗲𝘀𝘁 𝗰𝗮𝘀𝗲𝘀.
