Frontend разработчик

Build and ship production-ready SaaS features with React, Next.js, and TypeScript, focusing on reusable,
component-driven UI and a consistent design system.
• Designed a multi-tenant frontend architecture with role-based access control (RBAC) to serve isolated client
environments.
• Integrated AI-powered workflows into the product, automating manual steps and improving user efficiency.
• Developed real-time features using WebSocket for live data updates and in-app notifications.
• Delivered end-to-end functionality with REST APIs built on NestJS, Prisma, and PostgreSQL.
• Set up event-driven background processing (BullMQ, Kafka, Redis) for AI and report workers to improve scalability.
• Conducted code reviews and enforced modular architecture and DTO validation (Zod) to raise overall code quality.

Worked across two frontend stacks — React and Vue — delivering features in both and moving between codebases
as product priorities shifted.
• Implemented a Single Page Application (SPA) with React, improving application performance and user engagement.
• Built and maintained Vue components for internal interfaces using the Composition API and centralized state
management.
• Developed and integrated a fully functional embeddable widget that increased user engagement and satisfaction.
• Built responsive, cross-browser layouts with HTML, CSS, and JavaScript for a consistent experience across devices.
• Architected maintainable, scalable CSS using the BEM methodology for complex web applications.
• Integrated Lightweight Charts to deliver interactive financial data visualizations.
