Denis Vershadov

Monitored and visualized distributed systems on a dedicated infrastructure monitoring platform; designed UI for real-time dashboards, event-driven architectures, and performance optimizations; collaborated with backend, QA, and product teams on system behavior and data flows.

Built internal dashboards and tooling using React and TypeScript for monitoring and managing infrastructure; designed UI for visualizing asynchronous work flows and system state in distributed environments; collaborated with backend, QA, and product teams on trading workflows and system behavior; improved performance and usability of internal tools handling real-time data; worked with event-driven architectures (RabbitMQ) to optimize data flow and frontend integration; contributed to architecture discussions, code reviews, and sprint planning; implemented monitoring UI for distributed systems and real-time status updates.

Developed low-latency trading interfaces and crypto exchange platform UX; built scalable WebSocket abstraction layer to handle multiple real-time data streams (tickers, order book depth); optimized rendering for high-frequency updates via UI virtualization, significantly reducing UI lag under heavy data load; designed reusable React/TypeScript components and internal UI kit for multiple products; implemented crypto payments integrations and internationalization (i18next) with automated translation workflows; collaborated with backend, QA, and product teams on trading workflows and system behavior; participated in architecture discussions and code reviews.
