Developed and maintained the front-end architecture for three crypto products. Worked as the sole frontend engineer in the team, taking full responsibility for code quality, application stability, UI/UX, localization, and Sentry error monitoring. • DEX Aggregator: Developed a multi-chain token swap interface for EVM networks. Implemented blockchain interactions using viem and wagmi. Managed global state with MobX. • Cross-chain Platform: Enabled token swapping across distinct networks. Integrated near-intents API with support for all available EVM networks. Implemented non-EVM integrations (Bitcoin, Tron, Solana) for wallet connections, balance fetching, and transaction broadcasting. • Copy Trading: Built a functional interface for tracking and copying transactions of successful traders.

Worked in various teams on diverse commercial projects, quickly adapting to changing business tasks and technology stacks. Below are some of the projects: • Cardano Network Projects (MakerDAO analog & NFT Marketplace): Integrated real-time data via WebSockets, managed state with Redux Toolkit, and demonstrated Plutus smart contract technology. • Lending Pool (Web3/EVM): Executed UI redesign and implemented calculations/data visualization for DeFi metrics (APY, TVL). • PAB API Wrapper: Created an isomorphic library-wrapper, delivering unit tests, production use cases, and technical documentation. • Stories Administration Service: Developed a full-cycle MVP from database schema design to responsive UI using Nhost and GraphQL. • Healthcare Information System: Developed core features using Vanilla JavaScript and Node.js; covered interfaces with Cypress end-to-end tests. • UI/UX Design: Independently handled interface design for a part of the projects, delivering production-ready assets without a dedicated designer. • Mentorship: Guided interns, conducted code reviews, and helped them understand complex technical topics.
