Chatbot Assistant with Gemini + gRPC

This project is a simple chatbot backend powered by Google's Gemini API and uses gRPC for client-server communication. It maintains context per session and provides interactive conversational experiences.

Architecture

Features

• gRPC-based communication
• Google Gemini API integration
• Session-based context management
• Clean modular design (client, server, context manager, inference engine)
