I’m one of the core contributors to the Lido Community Staking Module, where I’ve been developing for the past two years. I’ve worked on both the on-chain smart contracts and off-chain infrastructure, including a performance oracle and a permissionless validator exit prover. Previously, I built monitoring systems for Lido validators across Ethereum and Solana, contributed to eth-docker with Obol and SSV integrations, and helped implement Core Protocol off-chain oracles for Lido v2. I specialize in designing high-quality software, with a passion for optimizing off-chain tooling — especially for Consensus Layer nodes. I also bring a strong testing mindset, including fuzzing, invariants, and both manual and automated testing. Right now, my main focus is delivering the most robust and user-friendly home staking solution on the market
One of the core developers of the Community Staking Module — a permissionless, home-staking solution in the Lido protocol. Contributed to both on-chain smart contracts and off-chain tooling, including performance oracle and validator exit prover. Automated and improved quality assurance processes for Lido’s staking protocol. Built and maintained internal tooling for validator testing and monitoring.
Developed and maintained pytest plugins and automated test coverage for Arenadata DB, Hadoop, QuickMarts, and Streaming products. Led load testing efforts using Locust, improving system stability under stress. Worked with Python, Pytest, Allure, Docker in complex data platform environments.
Built UI test automation for mobile apps (iOS & Android) of a major telecom operator. Maintained CI infrastructure and evolved in-house testing frameworks. Worked with Java, Maven, JUnit, Selenium, Appium, and Browserstack (App Automate & App Live).
Conducted functional and UI testing for mobile applications. Designed and implemented a cross-platform test automation framework for Android and iOS using Java, Selenium, and Appium. Mentored junior testers and led documentation and strategy development. Integrated test automation with App Center for continuous delivery.
