I've built Analytics OS V1.0, an AI-powered analytics platform that lets users query CSV, Excel, and SQL datasets in plain English through a retro-styled web interface.
I architected its LangGraph agent to translate natural language into DuckDB SQL, retry failed queries up to five times, select charts automatically, and generate executive-style insights using LLaMA 3.3 70B. I also implemented per-session DuckDB isolation for multi-user data privacy.
I've collaborated on Logic Lab, a full-stack educational puzzle game with 20 coding-logic levels, role-based student and admin access, dashboards, user management, and a global leaderboard.
I also created EchoLAN, a zero-server peer-to-peer LAN chat app using UDP discovery, TLS 1.3 encrypted messaging, SHA-256 device fingerprinting, and trusted-device verification.
