I will build ai chatbots and ai agents


About this gig
I build AI-powered systems that actually work in production not just demos.
What I can build for you:
RAG Chatbots Custom chatbots trained on your own documents/data using
LangChain, Pinecone, and reranking for accurate, hallucination-resistant
answers (not generic ChatGPT replies)
AI Agents Multi-step automation using LangChain/LangGraph with
tool-calling, so your agent can search, reason, and act not just chat
Machine Learning Models Prediction/classification models (XGBoost,
Random Forest) with SHAP explainability, so you understand exactly why
the model decides what it decides
API Integration Clean integration of OpenAI, Gemini, or Claude APIs
into your existing app, website, or workflow, with proper error handling
Recent work: built a medical RAG chatbot and improved answer faithfulness
from 0.75 to 0.96 through retrieval tuning and evaluation that's the
level of rigor I bring, whatever you're building.
I deliver clean, documented, working code deployed via FastAPI/Docker
or Streamlit when you need a live interface, or as source code if you're
integrating it yourself.
