You will get a custom RAG system using LangChain, LlamaIndex & OpenAI
Project details
I will build a custom RAG system using LangChain, LlamaIndex, OpenAI API, and Python to help you create AI applications that can search and understand your data.
This Retrieval-Augmented Generation (RAG) solution allows you to connect LLMs with your documents, PDFs, databases, or websites to build intelligent systems like AI chatbots, knowledge assistants, and internal tools.
The system can include document processing, embeddings, vector database integration, semantic search, prompt engineering, and GPT-based response generation.
Whether you need a simple prototype or a production-ready RAG system, I will deliver a clean, scalable, and business-focused solution.

Hi, I'm Shahab 👋
Most businesses are sitting on data they're not using and drowning in manual work they shouldn't be touching. I build the machine learning models, AI applications and dashboards that fix both and I make sure they actually ship, not just sit in a notebook.
Over the past 5+ years I've helped companies turn messy data and repetitive workflows into predictive models, LLM-powered tools, and BI dashboards their teams actually use to make decisions.
🔧 𝗪𝗵𝗮𝘁 𝗜 𝗰𝗮𝗻 𝗵𝗲𝗹𝗽 𝘆𝗼𝘂 𝗯𝘂𝗶𝗹𝗱:
- Data analysis & exploration, turning messy raw data into clear answers and insights
- Statistical analysis & A/B testing, hypothesis testing, significance, and confidence behind your decisions
- Data visualization & Power BI dashboards, reports non-technical stakeholders actually understand
- Predictive & forecasting models, churn, demand, pricing, classification
- AI assistants and chatbots powered by LLMs (OpenAI, Hugging Face)
- RAG systems that let a model answer from YOUR documents and data
- Power BI dashboards that turn raw data into clear, decision-ready reporting
- Python automation that removes hours of manual work every week
- End-to-end data pipelines cleaning, processing, deployment
🛠️ 𝗠𝘆 𝗧𝗼𝗼𝗹𝗸𝗶𝘁:
- 𝗗𝗮𝘁𝗮 𝗦𝗰𝗶𝗲𝗻𝗰𝗲 & 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀: Python, Pandas, NumPy, R, RStudio, SQL, Excel
- 𝗦𝘁𝗮𝘁𝗶𝘀𝘁𝗶𝗰𝘀: SciPy, statsmodels, hypothesis testing, regression, A/B testing
- 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴: Scikit-Learn, TensorFlow, PyTorch, XGBoost
- 𝗟𝗟𝗠𝘀 & 𝗚𝗲𝗻𝗲𝗿𝗮𝘁𝗶𝘃𝗲 𝗔𝗜: LangChain, RAG, Vector DBs, OpenAI, Hugging Face, AI Agents
- 𝗩𝗶𝘀𝘂𝗮𝗹𝗶𝘇𝗮𝘁𝗶𝗼𝗻 & 𝗕𝗜: Power BI, Plotly, Matplotlib, Seaborn
- 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 & 𝗗𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁: FastAPI, REST APIs, Docker, AWS, Streamlit, Git/GitHub
Whether it's a machine learning model, an AI chatbot, a RAG application, a Power BI dashboard, or an automation that buys back your week send me a message or invite me to your job. Tell me the problem you're trying to solve and I'll tell you the best way.
