Modular AI Chatbot Platform

I built multiple chatbot iterations that progressively added capabilities: basic OpenAI integration → conversation memory → tool/function calling → AI personality → database connectivity. Each version represented a distinct product capability milestone in conversational AI development.

Implemented Streamlit frontends with multiple backend versions demonstrating different AI patterns—simple prompt-response, conversation history management, weather tool integration, multi-tool orchestration, and database-connected user search.

This hands-on work gave me practical experience with OpenAI API patterns, tool calling mechanisms, conversation state management, and the engineering tradeoffs that shape AI product roadmaps.
