Davide Domenico Arcinotti

Currently developing a personal AI research project - a multi-agent system exploring different language models and their capabilities:

• Building a scalable multi-tenant system using TheNile (PostgreSQL) for vector storage and Redis for session management, focusing on efficient handling of embeddings and user interaction history.
• Implementing RAG (Retrieval-Augmented Generation) using LangChain (TypeScript), integrating multiple LLM providers (OpenAI, Hugging Face models, Claude) to enable model comparison and performance analysis across different use cases.
• Developing a modern React 19 frontend with TypeScript for intuitive visualization of cross-model responses and comparisons, with plans to expand into advanced user history management and result analysis.
• Creating a modular Node.js (Express/TypeScript) backend that handles multiple AI agents and manages parallel model interactions while maintaining conversation context and user sessions.

Currently working on:

• Extending the current RAG implementation to include CRAG capabilities
• Implementing comprehensive model response comparison features
• Enhancing user history tracking and analysis
• Exploring different embedding strategies and their impact on retrieval quality

This personal project started as a passion project to learn new technologies, but i came to architect an extended solution to fill some of the gap in current LLM experience for both private and B2B users. While i did start with Python ( FastApi, langraph ), i recently switched to Typescript as more performant and more in line with my expertise
