Built and maintained a suite of DeFi web applications for EVM-compatible networks utilizing React, Vite, Redux, Redux Toolkit, and Zustand for responsive user interfaces and accurate state management. Enabled real-time on-chain data indexing and synchronized off-chain processes by implementing background workers and API endpoints leveraging Express and WebSocket protocols. Developed and maintained smart contract integrations with Wagmi, RainbowKit, Viem, ethers.js, and web3.js to support efficient read/write operations along with deposit and withdrawal flows. Designed front-end state architecture for complex flows (wallet connection, balances, bridge steps, transaction history) using modern React patterns and React Query / TanStack Query. Integrated diverse blockchain protocols and APIs to expand platform compatibility, ensuring seamless support for applications across multiple decentralized networks including TON Chain and Steem. Directed full-stack development lifecycles by aligning cross-functional teams, establishing architectural decisions, and mentoring engineers through code review processes to elevate delivery standards and maintain robust, scalable DeFi products. Engineered and deployed a decentralized mini-game on TON Chain, leveraging smart contract logic and on-chain randomness to facilitate transparent gameplay while ensuring secure wallet authentication and seamless user experience.

Developed user-facing features for a React-based web application, focusing on clean UI and robust API integrations. Implemented views and components using React, SCSS and Redux, consuming RESTAPIs and handling loading/error states in a predictable and testable way. Refactored legacy components into more maintainable, modular structures, improving readability and reducing duplicated logic. Collaborated with product and design to translate requirements into technical tasks and delivered features end-to-end.

Coordinated the development of a mobile application project from requirements to delivery, working between business stakeholders and the development team. Managed scope, priorities and timelines; tracked progress and ensured that features were delivered according to specifications. Supported testing and acceptance, organized user feedback and turned it into clear, actionable tasks for the team.

Created custom CMS-based websites, single-page applications, and compact e-commerce platforms by utilizing ready-made scripts, pre-built themes, and supplementing functionality with PHP and JavaScript. Handled domain and hosting setup, basic server configuration and deployments for client projects. Performed integrations with common third-party services (payment, email, analytics) and provided maintenance and small feature updates for existing sites. Upgraded legacy client websites by implementing modern JavaScript frameworks and CSS pre-processors, enhancing user interfaces and ensuring compatibility with current browser standards.
