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 - 8:50 am local time
Senior Full Stack Developer and hands-on software architect with 10+ years building scalable SaaS platforms, AI-powered products, high-load systems and real-time web applications using React, Next.js, Node.js, TypeScript, PostgreSQL, AWS and modern cloud infrastructure. I help startups and scale-ups ship products that survive real traffic — shortening time-to-market, supporting rapid scaling and increasing system reliability.

As a Full Stack Developer I own the whole stack — one engineer who speaks both front end and back end, no handoff chain. Clients hire me as a Full Stack Developer for startup MVP development, as a React Developer for complex Next.js interfaces, as a Node.js or Backend Developer for scalable SaaS architecture and microservice architecture, as a Python developer for AI-heavy back ends or as the Web Developer and tech lead owning architecture inside a larger team.

What I deliver:

- 🧩 Frontend React / React Developer — React.js, Next.js, JavaScript, TypeScript, HTML, CSS, Redux, TanStack Query, MUI, Shadcn, Tailwind CSS, Bootstrap: responsive, accessible interfaces tuned for improving conversion rates and Web Design execution. Deploys on Vercel and AWS.
- ⚙️ Backend Nodejs / Backend Developer — Node.js, NestJS, Express, REST, GraphQL, WebSocket, gRPC, RabbitMQ: API Development, scalable APIs, event-driven architecture, CQRS, 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 and on Pinecone for vector search in AI workloads.
- ☁️ Cloud & DevOps — AWS, Kubernetes, Docker, Terraform, Nginx, Prometheus, Grafana, Git, CI/CD: scalable infrastructure, monitoring, zero-downtime releases, reducing infrastructure costs and operational bottlenecks.
- 🤖 AI — OpenAI and Anthropic Claude integrations, LLM pipelines, RAG, prompt engineering, MCP, AI agents, agentic systems, AI copilots, AI workflows, AI automation: shipping AI-powered products and AI Integration since the earliest OpenAI APIs.
- 🔗 Web3 — Solidity, smart contracts, DeFi, EVM and Solana/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.

Beyond the core build I handle third-party and payment integrations, API integration, admin dashboards, real-time features, performance audits and legacy modernization. Where a project calls for it I also work as a WordPress Developer or on Shopify and PHP/Laravel for content-heavy sites, e-commerce stores and CMS-to-custom migrations toward modern Node.js + React. I work as a Vue.js or Angular developer on existing front end codebases too. That modernization work often means migrating teams off Webflow or aging .NET back ends onto a modern Node and Next.js stack. When web, mobile or desktop need a single owner, I step in as a Mobile App Developer and Desktop Application engineer — React Native, PWA and Electron-based apps on the same Node.js back end. Testing, QA and observability are part of delivery, not an afterthought.

Selected results as a Full Stack Developer and tech lead:

- ⭐ Scaled a Node.js + React platform from 500K to 15M+ users; cut response times 1500%+ via re-architecture, caching, async processing — supporting rapid scaling.
- ⭐ Built a SaaS lead-management platform (Node.js + Next.js) from MVP in 10 days to 1M+ leads/year at 99.9% uptime — shortening time-to-market and increasing system reliability.
- ⭐ Designed a real-time blockchain analytics product on Node.js with React dashboards; wallet aggregation dropped from ~10 minutes to 5–40 seconds.
- ⭐ Delivered a marketplace aggregator 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 as one accountable role — domain-driven design (DDD), Software Architecture & Design, Software Development, Web Development, Web Design execution, deployment and post-launch Performance Optimization. I'm equally comfortable as the solo engineer on a startup MVP or as a tech lead mentoring a team, improving developer velocity and aligning with product, design and business stakeholders. Clear communication, predictable delivery, commercial outcomes.

If you need a Full Stack Developer, React Developer or senior Node.js developer who can lead architecture and ship across Next.js, Node.js, databases, cloud and AI — let's talk.
