About Me

I'm a Quality Assurance Engineer with a passion for blockchain technology and on-chain data analysis. My professional background in QA for public transport systems has taught me the importance of reliability, thorough testing, and data accuracy—skills that work really well in the blockchain space.

My Blockchain Journey

Beyond my professional work, I've immersed myself in Web3 by building real applications. I developed MEV bots and sniping systems, which required understanding mempool dynamics, smart contract interactions, and performant infrastructure. I run my own blockchain nodes (Erigon and Geth) on BSC and Ethereum, analyze smart contracts for vulnerabilities (protecting investors from rugpulls and honeypots), and use tools like Foundry and Anvil for contract simulation and testing.

Technical Approach

I combine solid QA practices (ISTQB certified, Agile) with hands-on blockchain development. My experience includes building automated test suites (Robot Framework, Selenium), CI/CD pipelines, monitoring dashboards (Grafana), and working with databases like MongoDB and MySQL. I develop custom tools in Python and Go for data analysis and automation.

I'm fascinated by the transparency of on-chain data and eager to bring my QA expertise and genuine passion for blockchain to a team working in the Web3 space.
