Middle+ React Developer
Frontend Developer with 4+ years of commercial experience in React, TypeScript, and Next.js. I build and evolve complex commercial products, from Enterprise SaaS and PropTech to e-commerce and real-time systems.
● Development — comfortable owning frontend development from architecture and feature implementation to backend integration and production release.
● Engineering mindset — experienced in working with large datasets, complex interfaces, and existing codebases. I focus on refactoring, reducing technical debt, and finding solutions that make products easier to develop and maintain.
● Performance & AI — focused on product performance and quality, using modern optimization approaches and AI tools as part of my daily development workflow.
● Expanding expertise — work with React Native and Expo and enjoy taking on new technologies and challenges that require independent problem-solving and a practical approach.
I prefer problems that require understanding the underlying challenge and finding the right solution rather than simply following a predefined specification. Open to new technologies and projects where I can expand my expertise and deliver practical results.

Experience
Senior React Engineer
Contract Frontend Developer 2025 - 2026
Project-based frontend consulting across Enterprise SaaS, AI, and PropTech products. Worked on Respology, an Enterprise SaaS platform using AI for social media comment moderation and analysis, and iHaven, a PropTech platform for residential real estate. Delivered 11 key screens for iHaven and 7 for Respology within tight project timelines of up to 2 months per project. Built 6 analytics modules with Recharts and React Query, integrating backend data into interactive charts with responsive layouts and animations. Optimized initial render of pages with analytics content to approximately 400 ms, measured with Chrome DevTools and Web Vitals. Developed a data-driven UI system where interface content and structure were generated from backend configuration, including dynamic blocks, cards, images, sizes, and CTA elements. Implemented interactive experiences with Framer Motion, including scroll and hover effects, smooth transitions, and micro-interactions. Worked closely with an international team on task decomposition, technical discussions, code reviews, and frontend architecture decisions
React Frontend Developer
sixhands 2024 - 2025
Took primary responsibility for frontend development of a VPN platform after team redistribution. Migrated the codebase from JavaScript to TypeScript and reworked the architecture of 7 key pages. Refactored 40+ components, including the decomposition of components exceeding 700 lines into 30+ reusable modules. Reduced file size to under 150 lines in the refactored areas and increased component reusability to approximately 90%. Reduced duplicated business logic by approximately 60% by moving server state and caching to TanStack Query and simplifying global state with Zustand. Reduced data fetching and rendering time from approximately 1.5–2 s to 0.2–0.3 s, while filter interactions improved from about 0.7 s to ~0.1 s. Reduced production dependencies by approximately 20% by replacing unnecessary third-party solutions with native implementations and optimized the bundle through code splitting and lazy loading, reducing bundle size by about 30%. Improved Core Web Vitals to approximately 1.6 s LCP and 150 ms INP, measured using Chrome DevTools and Web Vitals.
React Frontend Developer
CYBERPRAVDA 2023 - 2024
Built a knowledge graph editor supporting branching arguments, confirmations, refutations, comments, and reuse of existing graph sections. Developed SVG-based visualization for graphs with 700+ nodes, including automatic structure generation using the Phyllotaxis algorithm. Implemented zooming, panning, and interactive graph manipulation for large data structures. Introduced lazy loading, reducing initial graph rendering time from approximately 3 s to 0.75 s. Added caching for graphs and their versions, reducing repeated graph loading from approximately 3 s to 0.7 s and version switching from 1.5 s to 0.6 s. Delivered 10+ key user scenarios, including authentication, user profiles, chat, real-time notifications via WebSocket, and profile management. Integrated 15+ REST APIs, handling data processing and communication between frontend and backend services. Worked with Figma, i18next, code reviews, technical discussions, and frontend architecture

Implemented the full order workflow with a dynamic form containing 10+ fields, parameter changes, approval flows, 7+ delivery statuses, and photo reports. Built real-time functionality with WebSocket, including chat with response times below 100 ms and order status synchronization below 250 ms. Integrated 10+ REST APIs and Google Maps API for pickup and delivery address selection. Implemented media processing and storage with response times below 200 ms. Optimized order management with search response times below 500 ms and filtering/sorting across 4+ criteria. Used Redux for application state management and implemented localization for 2 languages with i18next. Analyzed 10+ user scenarios and improved UX flows, reducing some processes from 7–9 steps to 3–5 in collaboration with designers and the development team
