CS & AI / Builder / Educator

About

I'm a computer science graduate (M.S., Tufts University) with a background in economics. I focus on AI, robotics, and building practical tools that bridge technology and real-world needs. Currently planning an interactive teaching platform for CS & AI education.

Current Focus

Building

Interactive CS & AI Teaching Platform

My mission: make education simpler with AI — so anyone can master complex concepts and build real projects with ease. I'm creating an interactive platform for CS & AI learning, featuring hands-on exercises, visual explanations, and progressive paths from zero to deployment.

Featured Projects

A.L.I.C.E.

A.L.I.C.E. x Generative Agents

Open Source

A 2D Westworld — five AI villagers live, scheme, and dream in a simulated medieval world. They plan their days, reflect on past events, and consolidate memories each night. Built on Stanford's Generative Agents architecture.

Generative Agents FastAPI LLM WebSocket
Color Calibration

Real-Time Color Calibration Card

Live Demo

An end-to-end ML-powered color calibration system — from model selection and training to real-time browser deployment. Identifies and corrects color deviations through your camera in real time.
