Node.js Backend Developer Dmitry has shown an amazing level of development skill as a full-stack developer. He helped other teammates solve their dev problems and overall is great to work with! He's very responsive, literally available all the time. Also it worths mentioning that he's not overcharging like many other freelancers. If he needs to research something for a couple of days it he does it without billing the client. I can definitely recommend working with him.

Kharkiv, Ukraine - 2:14 pm local time
Top-tier Full Stack Developer on Upwork — 100% JSS, $190K+ earned, 4,500+ hours delivered. 10+ years building React Node platforms, AI-powered products, and high-load SaaS systems on Node.js, TypeScript, React, Next.js, PostgreSQL, and AWS. I help founders ship startup MVPs fast and take high-load systems from breaking to boring.

I own the stack as one engineer — front end, back end, data, infrastructure, AI. Clients hire me as a Full Stack Developer for startup MVP development and Full-Stack Development, as a React Developer for complex Next.js interfaces, as a Backend Developer or Node.js developer for scalable SaaS architecture and microservice architecture on React Node stacks, as a Python Full Stack Developer when AI pipelines lead the build, as a Full Stack Developer Shopify or Full Stack Developer Laravel engineer for commerce and content-heavy sites, or as a Web Developer and tech lead owning Software Architecture & Design across a larger team.

- 🧩 Frontend and React Developer — React , React.js , Next.js , JavaScript , TypeScript , HTML , CSS , Redux , TanStack Query , MUI , Shadcn , Tailwind CSS , Bootstrap : responsive , production-ready Web Development tuned for improving conversion rates. Deploys on Vercel and AWS .
- ⚙️ Backend and Node.js Developer — Node.js , NestJS , Express , REST , GraphQL , WebSocket , gRPC , RabbitMQ : API Development , scalable APIs on React Node stacks , event-driven architecture , microservice architecture , fault-tolerant systems , horizontal scaling .
- 🗄️ Data — PostgreSQL , MongoDB , MySQL , Redis , Prisma , TypeORM , Mongoose : clean data models tuned for high-load systems and multi-tenant SaaS . Comfortable on Supabase alongside my usual PostgreSQL setups .
- ☁️ Cloud and DevOps — AWS , Kubernetes , Docker , Nginx , Prometheus , Grafana , Git , CI/CD : scalable infrastructure , monitoring , zero-downtime releases .
- 🤖 AI — OpenAI integrations , LLM pipelines , RAG , prompt engineering , MCP , AI agents , AI agent builder , AI agent automation , AI agent creator , n8n-style automations . Shipping AI-powered products and AI Integration since the earliest OpenAI APIs .
- 🔗 Web3 — Solidity , smart contracts , DeFi , EVM and Solana and TON chains , HD wallets , blockchain analytics , secure financial flows for fintech infrastructure .

Industries: FinTech , SaaS , CRM , E-commerce , Marketplace , B2B platforms . Services: MVP Development , SaaS Development , AI Integration , API Development , Performance Optimization , Business Development support .

Beyond the core build I handle payment integrations, API integrations, admin dashboards, real-time applications, performance audits, and legacy modernization. Where a project calls for it I take on PHP , Laravel , Laravel Vue , and WordPress work for content-heavy sites and e-commerce stores, migrating to a modern MERN or React Next Node Supabase stack. On existing front ends I step in as a Vue.js or Angular developer. When web, mobile, and desktop need a single owner, I work as a Mobile App Developer for React Native , PWA , and Electron-based Desktop Application on the same Node.js back end. Plus Ruby on Rails when teams need it. Adjacent to usual builds: Etsy marketing , Pinterest marketing , and sales agent flows where AI agent automation moves the metric. QA, testing, and observability are part of delivery.

- ⭐ Re-architected a React Node platform from 500K to 15M+ users; 1500%+ faster response times via caching and async processing.
- ⭐ Built a SaaS lead-management platform on Node.js + React from a 10-day MVP to 1M+ leads/year at 99.9% uptime.
- ⭐ Designed a real-time blockchain analytics platform with Node.js back end and React dashboards; wallet aggregation dropped from ~10 minutes to 5–40 seconds.
- ⭐ Delivered a marketplace aggregator on React Node processing 1M+ items in near real time with anti-fraud and double-entry financial controls.

Stack: Node.js , TypeScript , React , Next.js , NestJS , PostgreSQL , MongoDB , Redis , RabbitMQ , AWS , Kubernetes , Docker , Golang , Python , PHP , Laravel .

How I work: I treat Full-Stack Development on a React Node stack as one accountable role — Software Development , Software Architecture & Design , Web Development , deployment , and post-launch Performance Optimization . Equally comfortable as the solo engineer on a startup MVP or as the tech lead mentoring a team and aligning with product, design, and business stakeholders. Predictable delivery, clear communication, commercial outcomes.

If your project aligns with React Node , scalable SaaS architecture , startup MVP development , or AI Integration — let's talk. Hire me as a Full Stack Developer , React Developer , Python Full Stack Developer , or senior Node.js engineer.
