I will be your python ai engineer for llm, rag, nlp and ml apps


About this gig
Want to build a custom AI app, connect your documents to a smart chatbot, or automate data tasks using Python?
Most AI scripts work in a demo but break with real data. I build clean, reliable Python AI systems that work smoothly in real life with zero fake answers.
WHAT I CAN BUILD FOR YOU:
Custom RAG Chatbots: Connect your PDFs and docs to GPT-4o using LangChain and ChromaDB,Pinecone with exact page citations.
Smart AI & SQL Agents: Build AI agents with memory that safely search live SQL databases and automate customer support.
PDF & Invoice Extraction (OCR + NLP): Pull clean JSON,CSV data from messy invoices, receipts, and PDFs, plus text analysis.
Machine Learning & Computer Vision: Train ML models (Pandas,Scikit-Learn) or build image upscaling tools using PyTorch, OpenCV, and ONNX.
Web Apps & APIs: Turn your code into an interactive Streamlit dashboard or a fast FastAPI backend.
WHAT YOU WILL GET:
Clean Python Source Code (easy to run)
Working Web App or API
Setup Guide & post-delivery support
Send me a quick message with your project details before ordering, and lets build it!

FAQ
What is your development tech stack?
I primarily build solutions using Python, LangChain, OpenAI API, ChromaDB/Pinecone for RAG systems, PyTorch and OpenCV for Computer Vision, FastAPI for backend microservices, and Streamlit for interactive user interfaces.
Can you connect my custom PDF documents or internal database to an AI chatbot?
Yes! I specialize in building custom Retrieval-Augmented Generation (RAG) systems and SQL-integrated AI agents that securely query your proprietary documents or databases with exact source citations and zero hallucinations.
Do you provide the complete source code after project completion?
You will receive clean, well-commented, and modular Python source code along with a deployment guide or setup instructions so your team can easily run or scale it.
Should I message you before placing an order?
Yes, I strongly recommend messaging me first with your project requirements. This helps us discuss the optimal architecture, tech stack, and timeline to ensure we deliver the exact results you need.
