QA Leader with 10 years in IT and leadership experience since 2022. I specialize in building QA processes tailored to the needs of each company — from early-stage startups to mature platforms. My profile is full-stack QA/SDET: I work across manual and automated testing, backend and frontend, test strategy, architecture, and team management.
I have deep experience in both CeFi and DeFi crypto projects, with a particular passion for decentralized finance and blockchain technologies. I’ve worked extensively with smart contracts, ABI, and trading infrastructures. Currently leading QA at 3Commas, driving automation and quality at scale.
