Oleksii B
À propos de ce service
Is your team spending hours answering the same questions, processing documents by hand, or doing repetitive tasks that could be automated? I build AI systems that actually work inside your business not just a generic ChatGPT wrapper.
What I deliver:
RAG chatbots that answer from your docs and knowledge base, with sources
Multi-agent systems that research, draft, classify and take real actions
Integrations with your tools CRM, email, Telegram, APIs
Production setup: prompt/version control, logging, cost limits, fallbacks
My background:
I built a production 7-agent LangGraph system on Azure AI Foundry at Accenture, handling real workflows with real users so I know what it takes to make AI reliable in production, not just in demos.
Tech stack (you don't need to worry about this): LangGraph, LangChain, Azure OpenAI, OpenAI API, RAG, FastAPI, PostgreSQL, Docker.
Why choose me:
Production experience, not just prototypes
Clear scope, honest timelines, and source code you own
Fast replies I'll tell you what's actually possible
Drop me a message describing your use case I'll tell you exactly what's possible and how long it takes.

FAQ
What do you need from me to start?
Your use case, the data the AI should use (docs, knowledge base, or API access), and where it should live (website, app, Telegram, etc.). No clear spec? I'll help you define one.
What's the difference between a chatbot, RAG, and an agent?
A chatbot answers from a prompt; RAG answers from YOUR documents with sources; an agent takes actions (search, call APIs, update systems). I'll recommend the right fit for your goal.
Do I own the code, and can you keep my data private?
Yes — you own 100% of the code. For sensitive data I can run local models (Ollama) or your own cloud, so nothing leaves your environment.
