You will get a custom RAG chatbot trained on your documents, PDFs, or website


Project details
You'll get a production-ready RAG (Retrieval-Augmented Generation) chatbot trained on YOUR documents — PDFs, websites, knowledge bases, support tickets, or any text data. The bot answers questions with accurate, grounded responses and citations back to the source, so users (and you) can trust every answer.
I'm a senior AI engineer who builds RAG systems for real businesses, not toy demos. Stack: LangChain / LlamaIndex, OpenAI / Anthropic / open-source LLMs, vector databases (Pinecone, Weaviate, Qdrant, pgvector), and clean web UIs. I focus on retrieval quality, prompt design, and evaluation — the things that actually make a RAG chatbot useful vs. frustrating.
Whether you want a customer support bot, an internal knowledge assistant, or a research tool over hundreds of documents, I'll deliver a working chatbot deployed where your users actually are — your site, Slack, or a hosted dashboard. Source code included.

About Yaqov
Agentic AI Systems Architect | LLM Orchestration, Full-Stack & Busines
Shlomi, Israel - 4:10 pm local time
With 20+ years of hands-on experience as a CTO and AI Systems Architect, I specialize in the most in-demand areas of 2026:
▸ AGENTIC AI & LLM ORCHESTRATION
Multi-agent systems, autonomous decision-making pipelines, RAG architectures for enterprise knowledge bases, and custom integrations with Claude, OpenAI, DeepSeek, Groq, and Ollama.
▸ BUSINESS PROCESS AUTOMATION
End-to-end workflow automation using n8n, Python, and custom AI agents. From lead management to customer service to data pipelines — I replace manual work with intelligent, scalable systems.
▸ FULL-STACK SAAS & API DEVELOPMENT
Production-ready platforms built with React, Next.js, FastAPI, Node.js, and PostgreSQL. Microservices architecture, real-time dashboards, and seamless API integrations.
▸ DATA ENGINEERING & AI ANALYTICS
Data pipelines, BI dashboards, predictive analytics, and NLP systems that turn raw data into business intelligence.
What sets me apart: I don't just write code — I own the entire lifecycle from strategy and architecture to deployment and scaling. Clients get a technical partner who understands both engineering and business outcomes.
If you need a specialist who can build, automate, and scale your AI-powered system end-to-end — let's create something exceptional together.
