Graph-Powered RAG with Neo4j

- A hybrid RAG system combining Neo4j Knowledge Graphs with Vector Search for deep, connected data retrieval.

- Uses Groq for high-speed inference and Ollama for local embeddings, turning Wikipedia topics into a searchable intelligence hub.

- Synthesizes answers by combining direct facts from the graph with semantic context from vector search.

CodingAgent(CodeTablet)

- Multi-Agent Coding System: A sophisticated coding agent built with LangGraph that utilizes a three-tier architecture—Planner, Architect, and Coder agents—to automate software development.

- Automated Project Generation: Transforms high-level user task descriptions into fully functional codebases, delivering the final output as a downloadable ZIP file directly to the user's PC.

- Scalable Cloud Backend: Features a robust backend built with FastAPI and deployed on AWS EC2, ensuring efficient processing of complex coding tasks.

- Real-time Progress Tracking: Provides a Streamlit-based frontend that displays a live execution trace of the agent's reasoning and code generation steps.

- Proven Versatility: Capable of generating a wide range of applications, from basic HTML "Hello World" files to functional tools like calculators and countdown timers.
