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 - 9:46 pm local time
Top Rated Web Developer in the top 1% of talent in development — 100% JSS, $190K+ earned, 4,500+ hours delivered. 10+ years building websites, web applications and high-load platforms as a Node.js Developer and React Developer — from startup MVPs and custom web design to systems serving 15M+ users. I pair full-cycle Web Development with Full Stack AI: LLM integrations, AI agents and RAG pipelines built into real products.

I own the full stack as one engineer. Hire me as a Web Developer for website developer builds, website redesign, web application development and ecommerce website development; as a Node.js Developer for backend developer work, API development and node.js backend developer services; as a React Developer for react web developer projects, web app developer react builds and react native developer front ends; or for Full Stack AI — AI agent development, AI app development and full stack developer ai agents wired straight into your product.

Performance Optimization

Beyond the core build I handle admin dashboards, real-time applications, performance audits and legacy modernization. I step in as a WordPress Development, Shopify Development and CMS Development partner — wordpress developer work included — for content-heavy and commerce sites, and as a Website Builder or Website Customization specialist handling back end web developer and back end developer node.js work on existing codebases. For mobile I deliver App Development and Mobile App Development with React Native — iOS Development, iPad App Development and Android App Development from one codebase.

I also adapt to whatever stack a project already runs on:

CRM Development, web developer ecommerce flows, QA and observability are part of delivery.

How I work: I treat Web Development as one accountable role spanning Software Architecture & Design, Software Development and Full-Stack Development, through deployment and post-launch Performance Optimization. Comfortable as the solo engineer on a startup MVP or website, or the tech lead mentoring a team across product, design and business stakeholders. Predictable delivery, clear communication, commercial outcomes.
