I build performant React and Next.js products, from SaaS interfaces to real-time platforms and admin systems.
What I'm looking for
I've built commercial React.js and Next.js products for Respology, iHaven, sixhands, CYBERPRAVDA, and Friendly Carrier—from Enterprise SaaS and PropTech platforms to VPN portals, online stores, and real-time logistics services.
For iHaven, I developed 30+ reusable React components, contributed to 70% of product pages, and built dynamic data visualizations with Recharts and React Query. I optimize interfaces for responsive use, interactive scenarios, and fast loading, including analytical pages loading in about 400 ms.
At sixhands, I migrated a VPN portal from JavaScript to TypeScript, refactored 70+ components, and moved the architecture toward reusable modular development. I also built an online store with Next.js, Tailwind CSS, YooKassa payments, token-based authorization, an administrative panel, and scalable data tables.
I prefer an engineering approach: thoughtful architecture, reusable UI systems, performance optimization, and solutions that remain convenient as products evolve. My work includes REST APIs, GraphQL, WebSockets, state management, localization, legacy refactoring, and real-time user experiences.
