Job Success
Kyiv, Ukraine - 8:51 am local time
🛰️ Built a platform for NASA Geochron
🎥 Shipped video streaming apps handling 100,000+ concurrent users
💰 Helped clients generate $1.5M+ in revenue through web and mobile products
📱 Delivered 100+ projects across web, React Native Mobile, and Node.js backends - startups, SaaS, fintech, healthcare, and B2B
I'm a Senior React Developer and Full Stack Developer React Node with 9+ years of experience on the frontend and hands-on backend experience building production-ready web, mobile, and server-side applications. As a Full Stack Developer React Node, I work across the entire stack - from MVP prototypes shipped in days to complex SaaS platforms built to scale.
Whether you need a React Developer for web application, a React Native Developer for your app, a Node.js backend, or all three - I build things that work, perform, and hold up in production.
🔧 Tech I work with daily:
React.js | Next.js | TypeScript | React Native | Node.js | Express.js | PostgreSQL | MongoDB | Redux | Zustand | Tailwind CSS | shadcn/ui | REST API | GraphQL | OpenAI API | WebSocket | Figma
🌟 What I actually do well
🔹 React & Next.js Web Applications
From SaaS dashboards and admin panels to marketplaces, fintech platforms, and B2B tools - I build clean, scalable frontend React frontends that real users rely on daily. As a React Developer, I get into existing codebases, not just greenfield projects.
🔹 Node.js Backend & API Development
As Full Stack Developer React Node, I have hands-on experience building REST APIs, GraphQL endpoints, authentication systems, background jobs, and database architecture using Node.js and Express. Backends designed to support the same scale and reliability standards as the frontends I ship.
🔹 React Native Mobile Apps
Cross-platform iOS and Android development using React Native. As a React Native Developer, I've shipped mobile apps to the App Store and Google Play, and I know the difference between demo-ready and production-ready.
🔹 MVP & Prototype Delivery
Startup mode is where I'm comfortable as well. As Full Stack Developer React Node I translate concepts into working React Next.js, Node.js, or React Native Mobile prototypes fast, without sacrificing the architecture decisions that matter later.
🔹 Real-Time & Complex UI
WebSocket integrations, live dashboards, streaming interfaces, real-time data flows - built and shipped across multiple platforms including a video streaming product at 100K+ concurrent users. As Full Stack Developer React Node, I take on each project with this same level of care.
🔹 AI-Powered Apps
OpenAI API integrations into web, mobile, and Node.js backend products - chat interfaces, AI assistants, content generation tools - built as production features, not demos. My work as a Full Stack Developer React Node means these are shipped as real, scalable, end-to-end features.
🔹 Figma to Production
Pixel-accurate implementation of Figma designs across React Next.js and React Native Mobile projects. As React Developer and React Native Developer I've worked directly with design teams and solo designers - I know how to read a design file and ask the right questions.
🔹 Performance & Code Quality
Core Web Vitals, bundle optimization, API performance, database query tuning, clean component and service architecture - I write Next.js TypeScript and Node.js code that the next developer can read and extend. Clean handoff is non-negotiable.
