9+ years of experience in software development, with a strong focus on React.js, Next.js, Node.js, and building complex high-load web applications.

I have extensive experience with the React ecosystem, including React Query, Redux, Redux Thunk, Redux Saga, Redux Observable, MobX, RxJS, as well as Node.js and Express.js. I also work extensively with Next.js, including SSR, server-side data fetching, performance optimization, and application architecture.

I have designed and evolved application architectures from scratch and worked with Domain-Driven Design, Clean Architecture, and Feature-Sliced Design. I have experience making architectural decisions for large applications, splitting systems into modules and domains, improving maintainability, and reducing coupling between different parts of the product.

I have worked on real-time and data-intensive applications using WebSockets, including live market data and continuously updating interfaces. I have integrated and customized TradingView-based charting solutions and worked with financial and trading interfaces where performance, latency, and efficient data updates are critical.

I have strong experience in frontend performance optimization: identifying bottlenecks, reducing unnecessary rendering and network requests, optimizing Web Vitals, improving client/server interaction, reducing backend load, and investigating production issues using tools such as Sentry and browser performance tooling.

I am also familiar with E2E and unit testing and have worked with various UI libraries including Material UI, Ant Design, and Bootstrap, as well as building reusable component libraries and Storybook-based design systems.

I have worked in very different engineering environments: small teams of around 10 people with minimal QA infrastructure, large organizations with 50+ developers across multiple engineering and QA teams using Agile processes, planning, daily meetings, and retrospectives, as well as startups with fast-moving and less formal task management.
