About Me

I'm a Computer Science and Data Science student @ Boston University, currently working in Full-Stack Development and AI/Machine Learning. There are infinite problems in the real world. Still, I aim to simplify them one step at a time through fun, interactive experiences/visuals that more of the general audience can understand.

✏️ What I'm Currently Doing

  • Building the Sapling campaign to prepare for the first beta launch university-wide
  • Diving deeper into full stack development
  • Studying system design & architecture

🌱 Sapling - Best AI in Education, BU CivicHacks 2026

AI Study Platform Powered by a Dynamic Neural Knowledge Graph

An school-community based platform that turns a student's own documents into an AI tutor, then visualizes everything they've mastered as a real-time knowledge graph.

  • 🧠 Three AI tutoring modes: ocratic, expository, and teach-back
  • 🌐 Real-time D3.js knowledge graph that tracks mastery as you learn
  • 👥 Collaborative study rooms over WebSockets; equipped with live chat, matchmaking & side-by-side graph comparison
  • 📄 Upload any document → AI classifies, summarizes & extracts assignments
  • 📚 Practice with personalized flashcards and quizzes, with in-depth knowledge mastery calculations by Gemini

🍄 Super Artificial Bros. - Best Use of AI & LLMs, BostonHacks 2025

Fully AI-Generated Mario Levels Powered by Gemini

A reimagined Super Mario Bros. where Gemini procedurally generates entire playable levels on the fly and an AI relationship system rewrites the game around how you play.

  • 🌍 Infinite, never-repeating levels generated end-to-end by Gemini, no hand-authored maps
  • 🤝 Relationship algorithm with Toad, Goomba & Koopa that drives AI-generated NPC dialogue and branching story choices
  • 🧠 Contextual memory system that tracks long-term player decisions and dynamically tunes difficulty, enemy spawns & rewards
  • ⚙️ Full-stack AI pipeline: Python + Gemini backend feeding a real-time HTML5 Canvas game engine

🏛️ Stalk Market - Best Technical Execution, BU Data Science + X 2026

AI-Powered Stock Market Simulator for Learning to Invest (Stardew Valley Style)

An interactive financial-literacy game where stocks grow like plants in a garden, so beginners can learn investing safely through simulation instead of risk.

  • 📈 Hybrid pricing engine fusing Geometric Brownian Motion + jump-diffusion with a transfer-learned GPT-2 adapted for numerical price sequences
  • 🤖 Real-time ML risk engine (scikit-learn) trained on 2,000+ Monte Carlo portfolios to predict drawdown, volatility, and risk class live
  • 🌎 Live macroeconomic data from the FRED API (CPI, Fed funds, recession & yield-curve signals) driving the market
  • 🎓 Education Mode that dampens volatility when you over-concentrate, teaching diversification by consequence
