You will get an AI RAG Assistant answers from your documents
Top Rated
Project details
You’ll get a fully functional RAG (Retrieval-Augmented Generation) chatbot that answers questions directly from your documents with high accuracy, zero hallucinations, and a clean user experience. This system transforms static PDFs, manuals, textbooks, medical notes, or internal knowledge bases into an intelligent assistant that works 24/7.
What sets this project apart is the architecture behind it: a carefully engineered pipeline using modern vector databases, advanced chunking strategies, and optimized prompt flows. You’re not getting a template—you’re getting a purpose-built, production-grade AI system structured exactly around your data and your workflow.
What makes this service different:
Tailored retrieval pipeline for your exact documents
Accurate, citation-based answers powered by LLMs
Multi-file ingestion with clean data normalization
A lightweight UI or API endpoint depending on your needs
Elastic, Chroma, or Redis-backed vector search for speed and relevance
Tech that drives the impact:
FastAPI, LangChain/LangGraph, OpenAI models, vector databases, Docker deployment, and optional RAG optimizer modules for boosting precision.

Job Success
Rotterdam, Netherlands - 12:55 pm local time
infrastructure to multi-agent workflows and RAG pipelines. My work spans
the full stack: GPU cluster management, model deployment, agentic system
design, and enterprise integration.
WHO I WORK WITH
Mid-to-large enterprises and funded startups who are past the "let's
explore AI" phase. You have a real problem — high support volume, slow
internal knowledge access, manual workflows — and you need an engineer
who can take it from architecture through production deployment, not
just an API wrapper.
WHAT I SHIP
• RAG systems — PDF/document/database-grounded assistants with hybrid
retrieval, reranking, evaluation. LangChain, LlamaIndex, LangGraph,
pgvector, Pinecone, Elasticsearch.
• AI agents — production multi-agent systems with tool-use, function
calling, MCP integration, stateful workflows.
• Voice AI — Retell, Twilio, Vapi, ElevenLabs conversational pipelines.
• Inference infrastructure — vLLM, SGLang, TGI, AWQ/FP8 quantization,
multi-GPU orchestration on Kubernetes.
• Full-stack delivery — FastAPI, Django, React/Next.js, Postgres,
MongoDB, Redis.
HOW I WORK
I build systems that are modular, observable, and production-ready —
not prototypes. Phoenix/OpenTelemetry instrumentation is in from day
one. Every ship has latency, cost, and reliability budgets attached.
Focus is always on measurable business impact, not vanity metrics.
RECENT ENGAGEMENTS
• Sovereign AI platform (1.4M+ users) — multi-provider LLM gateway on
4×A100 cluster with 130+ production agentic tools.
• Two-sided clinical AI platform — multi-agent nutrition coaching with
RAG over clinical knowledge bases, automating 100% of nutritionist
workflows.
• Top-5 global LLM education benchmark — raised accuracy 68% → 85%
through context engineering.
LET'S TALK IF
You have a real, concrete use case. You are looking for a data scientist and a software engineer who delivers end to end solutions with clean docs and trust and reliability as a feature.
Steps for completing your project
After purchasing the project, send requirements so Vahit can start the project.
Delivery time starts when Vahit receives requirements from you.
Vahit works on your project following the steps below.
Revisions may occur after the delivery date.
Understand your use case & data
I review your goals, target users, and documents to clearly define what the RAG chatbot should do and which data sources it will rely on.
Design the RAG architecture
I design the retrieval pipeline (chunking, embeddings, vector DB) and how the chatbot will combine user questions with your data to give grounded answers.
