Project details

I will help you build the first working version of your AI-powered web app or SaaS MVP.

This project is for founders, startups, and teams that need a real product, not just a quick AI demo. I can help with the main parts of the application: frontend, backend, database, authentication, AI integration, API layer, and deployment.

Typical stack:
• Next.js / React / TypeScript
• AI SDK / Vercel AI SDK
• Node.js backend
• PostgreSQL with Prisma
• OpenAI / Claude / Google Gemini
• pgvector if RAG or semantic search is needed
• LangChain or LangGraph if the AI workflow needs it
• Docker and API integrations

Examples of what I can build:
• AI SaaS MVP
• AI chatbot web app
• AI dashboard or internal tool
• AI document assistant
• RAG-based product
• AI workflow automation platform
• Admin panel with AI features
• AI integration into an existing web app

About Sergey

Sergey S.Status: Offline
Full-Stack AI Developer | Agents, RAG, Next.js, Node.js
Ponta do Sol, Portugal - 8:44 am local time
I help companies design and build AI-first products: LLM agents, RAG systems, internal automation tools, and full-stack SaaS applications. I build AI tools that are actually connected to real products, workflows, and data.

Most of my work is at the intersection of full-stack development and AI implementation: LLM agents, RAG systems, internal tools, automation workflows, dashboards, and SaaS MVPs.

I can help with both the technical architecture and the implementation: frontend, backend, database, APIs, AI integrations, embeddings, deployment, and workflow logic.

What I usually work with:
• LLM agents and AI workflow automation
• RAG systems over documents, databases, and knowledge bases
• OpenAI API, Claude, embeddings, prompt logic
• Next.js, React, Node.js, TypeScript, JavaScript
• Python, PostgreSQL, Supabase, Docker
• n8n and custom automation pipelines
• Web3 infrastructure, blockchain data, validators, explorers

A few examples of my work:
• Citizen Web3 Ops Agent Factory — AI agents for operational workflows
• CW3 GitHub Agents — AI agents for engineering and repository workflows
• RAG Validatorinfo(dot)com — an AI assistant working with blockchain validator data

I’m a good fit for projects where AI needs to be more than a demo: connected to a real database, real users, real workflows, and a clear product goal.

If you need someone who can think through the architecture and also build the actual system, I can help.
