Project details
I build production Multi-Agent RAG platforms for SaaS, FinTech, LegalTech, and EdTech teams that need an AI Agent stack doing real work — not a demo.
Not a single-prompt chatbot: a LangGraph supervisor with specialist sub-agents for retrieval, reasoning, tool calls, citation checking, and safety. Wired to a RAG pipeline (semantic chunking, hybrid BM25 + dense retrieval, reranking, pgvector/Pinecone) and an MCP server exposing your internal APIs, databases, and tools to the agent — or to Claude Desktop / Cursor for your team.
Full production stack: LangSmith traces on every agent step, Ragas eval pipeline in CI, PII redaction, jailbreak detection, per-tenant isolation, FastAPI streaming backend, Docker + IaC for AWS / GCP / Azure.
Integrations ready on day one: Notion, Confluence, SharePoint, Google Drive, S3, Postgres, Salesforce, HubSpot, Slack, your REST / GraphQL APIs.
My profile: $200K+ earned on Upwork, Top Rated, 100% Job Success, 10 certifications in LangGraph, Multi-Agent Systems, MCP, and RAG. Every engagement ships under NDA with measurable eval metrics.

Lebenswerk.ai
Working with Volodymyr on the Lebenswerk.AI app has been an excellent experience from start to finish. He is highly skilled across the full stack — Android, iOS, back-end development, Azure hosting, and ChatGPT integration — and consistently delivers thoughtful, reliable solutions.
What stood out most to me is how solution-oriented he is. He does not just implement tasks; he actively thinks ahead, makes smart recommendations, and suggests improvements that add real value to the project. His technical expertise is obvious, but just as important is his ability to understand requirements quickly and turn them into practical, high-quality results.
If you are looking for a developer who is knowledgeable, proactive, and genuinely invested in building the best possible product, I can absolutely recommend him.

Job Success
Lviv, Ukraine - 3:48 am local time
As an AI Agent Developer I own the whole build - the agent logic, the RAG layer, the backend, the frontend and deployment.
⭐ PROVEN RESULTS
One AI SaaS product I built now serves 10,000+ users.
Lebenswerk.ai, a cross-platform AI app (Android, iOS, back end, Azure): shipped end to end, 5.0 stars, client called me "highly skilled across the full stack."
MVP for a pay-per-message product, delivered as a true partner, 5.0 stars: "thinks outside the box like an actual partner."
$200K+ earned as an AI Agent Developer building AI SaaS, MVPs, agents and RAG systems in Healthcare, Real Estate, Fintech and Marketplace.
🤖 WHAT I BUILD
As your AI Agent Developer I build AI agents and agentic systems, AI chatbots and RAG assistants that run in production, not in a demo. I wire AI into the product (WhatsApp, CRM, internal tools) and wrap it in a clean AI SaaS or MVP that holds up under real load.
AI stack: AI agents, RAG pipelines, LLMs, OpenAI and Anthropic Claude API, LangChain, chatbots, Generative AI, NLP and Machine Learning.
✅ WHY HIRE THIS AI AGENT DEVELOPER
You get one senior AI Agent Developer who can design the agent, build the RAG layer, ship the SaaS and deploy it - no hand-offs. Need an AI Agent Developer who actually ships? That's me.
✅ HOW WE START
Let's start with a short call or a small first milestone, so you can see the fit before committing. Tell me what you're building and I'll be honest about the best way to ship it.
