AI Assistant: Agentic Web Search & Math Solver

Built an intelligent AI agent that autonomously decides which tool to use—web search or a calculator—based on the user's query. Unlike a standard chatbot, this system uses agentic reasoning to route questions to the appropriate backend.

Engineering Challenges Solved:

Agentic Decision-Making: Implemented LangChain to give the LLM the ability to reason about user intent and select between a real-time web search tool (Tavily) and a secure mathematical expression evaluator.

Real-Time Information Retrieval: Integrated the Tavily Search API to fetch live, up-to-date answers for questions about current events and general knowledge.

Secure Math Evaluation: Built a sandboxed expression parser to safely evaluate mathematical queries without risking code injection, supporting complex calculations.

Tool-Calling Architecture: Designed a modular pipeline that allows the agent to chain multiple tools together when needed for complex queries.

Tech Stack: Python, LangChain, Groq API (Llama 3.1), Tavily Search API, Streamlit.
