Dimitriy G.

Senior Full Stack Developer with 7+ years of experience and 50+ complex web projects delivered from scratch. I build production-ready SaaS platforms, CRM systems, marketplaces, e-commerce products, AI applications, dashboards, and custom business software with React, Next.js, Node.js, and modern database architecture.

You may be launching a new product, rebuilding a slow or fragile system, adding AI or LLM functionality, or replacing disconnected tools with one scalable platform. I work with founders, startups, and established businesses that need a senior technical partner who understands product goals, user experience, and engineering quality.

WHAT YOU GET
✔️ End-to-end full stack development: architecture, UI, backend APIs, databases, integrations, testing, deployment, and ongoing improvements.
✔️ A maintainable codebase with reusable components, clear backend services, scalable data models, clean documentation, and knowledge transfer.
✔️ SEO-focused, high-performance applications using React and Next.js, including server-side rendering, responsive interfaces, and optimized user experiences.
✔️ Secure Node.js systems with authentication, role-based access, payments, APIs, WebSockets, background jobs, webhooks, and third-party integrations.
✔️ Clear communication, accurate estimates, transparent progress, practical technical decisions, and a long-term approach to product development.

REACT, NEXT.JS, NODE.JS & MERN
I specialize in React development, Next.js, TypeScript, Node.js, Express.js, Nest.js, MongoDB, PostgreSQL, Prisma, Drizzle ORM, and Supabase. I build responsive interfaces, admin panels, customer portals, REST APIs, real-time applications, and complete MERN stack systems. My frontend work focuses on clean UI/UX, reusable design systems, accessibility, performance, and SEO.

SAAS, CRM, E-COMMERCE & MARKETPLACES
I develop Full Stack Developer SaaS products, Full Stack Developer CRM platforms, Full Stack Developer Ecommerce applications, and Full Stack Developer Marketplace systems. Typical functionality includes multi-user access, subscriptions, billing, dashboards, search, filtering, product catalogs, checkout, order management, vendor tools, reporting, notifications, and custom workflows.

AI, LLM & AUTOMATION
I build Full Stack Developer AI products and Full Stack Developer LLM integrations, including AI agents, assistants, document-processing workflows, knowledge bases, semantic search, AI-powered search, structured outputs, and AI modules inside MERN applications. I work with OpenAI and ClaudeAI integrations, prompt workflows, user permissions, data storage, and backend orchestration so AI features become a reliable part of the product—not an isolated demo.
