Project details

Add Claude to your existing product without breaking what already works. I integrate the Anthropic API into web and mobile apps: assistants that use your tools and data, document analysis, content generation, agentic workflows with function calling, and streaming responses for smooth UX.

Why me: 89 delivered projects, 100% Job Success, Top Rated Plus. Recent Claude work includes MCP servers connecting internal tools to Claude Desktop, a multi-tenant AI SaaS serving 10,000+ users, and support agents handling 300+ chats a day in production.

How we start: message me with a couple of lines about your product and what you want Claude to do. The $50 kickoff gets you a written integration plan in 1 day, so you know the exact scope and cost before committing to the build.

Lviv, Ukraine - 12:27 pm local time
Most AI agent projects die at the demo. I ship the ones that survive contact with real data — 90 builds, $300K earned on Upwork, 100% Job Success, Top Rated Plus.

ABOUT ME

8+ years building AI agents, RAG systems and AI SaaS. Some of what I have shipped:

- A multi-tenant AI SaaS platform serving 10,000+ active users, with Stripe billing, RBAC and row-level security, built end to end
- A RAG chatbot handling 300+ chats a day in production for a UK energy company, doing support and lead capture
- RAG pipelines that processed 100K+ invoices and bills of lading for port logistics, cutting manual work by 90%
- A cross-platform AI app (iOS, Android, Azure backend) shipped solo in 3 months, 5.0 stars on both stores
- 50+ automation workflows in n8n and Make, wiring AI agents into CRMs, Slack, Telegram and WhatsApp
- 15+ custom MCP servers connecting client APIs and databases to Claude, ChatGPT and Cursor

WHAT I BUILD

AI agents and agentic systems with LangChain, LangGraph and MCP: tool calling, multi-agent workflows, error handling, observability, real production deployments.

AI SaaS platforms and MVPs on Next.js, Node.js, Python FastAPI, Supabase and Stripe. Idea to production in 6-12 weeks.

RAG chatbots and assistants for support and lead generation, on WhatsApp, Telegram and web widgets, with CRM integration and human handoff.

Retrieval pipelines on pgvector and Pinecone: embeddings, hybrid search, reranking, grounded answers with citations.

OpenAI and Anthropic Claude API integrations inside products that already have users, without breaking what works.

WHERE I HAVE WORKED

Healthcare, real estate, fintech, edtech, ecommerce, port logistics and energy. Document automation and OCR, customer support AI, knowledge bases, voice and chat.

HOW I WORK

One senior engineer, no hand-offs. Agent logic, retrieval layer, backend, frontend and deployment come from the same person. You get one thread, not a queue.

HOW WE START

Book a $50 consultation — my last 4 all turned into ongoing projects. Or pick a fixed-scope project from my catalog. Tell me what you are building and I will tell you the shortest way to ship it.

Steps for completing your project

After purchasing the project, send requirements so Volodymyr can start the project.

Delivery time starts when Volodymyr receives requirements from you.

Volodymyr works on your project following the steps below.

Revisions may occur after the delivery date.

Kickoff & integration plan

You describe the product and the goal. I map the integration points, choose the right Claude models and tools, and deliver a written plan with scope and cost.

Build & integrate

I implement the Claude integration in your codebase: prompts, tool use, streaming and error handling, tested on your real data.

Review the work, release payment, and leave feedback to Volodymyr.
