I build Web3 test automation that protects critical DeFi user flows.
BelarusWhat I'm looking for
I've built Python-based test automation for a DeFi Web3 startup, covering UI, API, and smart contract interactions across critical user flows. My work achieved 80% test coverage and reduced manual regression testing time sixfold per release cycle.
At FRAKT, I established the first formal QA process for an NFT lending protocol, cutting critical post-release bugs by over 50% within six months. I also proposed 10 UI/UX improvements through exploratory testing, including an onboarding change that reduced support tickets by 15%.
I combine hands-on smart contract and API testing with product-minded QA, including finding a critical smart contract vulnerability before launch. Earlier, at VironIT and Yandex, I delivered mobile testing strategies, API testing, and exploratory, regression, and smoke testing.
