I’m a Frontend Developer with nearly 3 years of commercial experience in building modern web
applications using React, Next.js, Redux Toolkit, and RTK Query.
My expertise includes developing interactive dashboards and data visualization tools with Chart.js,
ECharts, and D3.js, as well as integrating real-time WebSocket data streams.
I have worked on projects ranging from business CRM systems to analytics platforms for financial and
trading data, focusing on performance optimization, scalability, and user-friendly design.
Additionally, my background in UI/UX design tools (Figma, Photoshop, Illustrator) helps me effectively
bridge the gap between design and development.
