Projects

Next.js, TypeScript, Convex, MCP, Gemini API, OAuth

Intern

Shared memory layer for AI agents, exposed as an MCP server. Append-only event log with idempotent capture; agents draft email and Slack actions for human approval, and edits become preference facts the next agent retrieves, so behaviour improves without retraining.

Open ↗

Next.js, FastAPI, ReactFlow, Claude API, MongoDB, Unity MCP

GameGold

AI game design platform that takes a game from concept to ship in 7 stages: GDD generation with Claude, balance analysis with exploit detection, asset generation, Unity integration via an in-Editor MCP server, and AI playtesting across 4 personas.

Open ↗

React, FastAPI, CoinGecko API

CryptoDash

A full-stack cryptocurrency dashboard with live market tracking, interactive candlestick charts, crypto news, wallet-based portfolio analysis, and AI-style insight features.

Open ↗

Flask, OpenAI API, MongoDB

NOMinate

A recommendation system for meals that adapts to user feedback, balances dietary constraints, and supports both takeout and home-cooking decisions.

AWS Lambda, API Gateway, DynamoDB, Twilio

Fraud Detection Capstone

An event-driven fraud scoring pipeline that evaluates transactions in real time and loops customer feedback back into the risk system.

OpenCV, MediaPipe, OCR

Ultrasound Guidance System

A real-time perception system that helps non-experts reproduce expert scanning behavior with more consistency and less operator error.

Playable Work

Games

Unity, C#, 2D Horror

Veil

A horror game focused on atmosphere, progression, enemy behaviors, and modular systems that could expand without collapsing under their own weight.

Open ↗

GameMaker Studio, GML, Pixel Art

Community Cook

A pixel-art management sim about feeding a struggling town with limited ingredients, recurring NPCs, and a mechanics-driven nutrition scoring loop.

Analog + Digital Prototypes

UW Game Lab Research

Short-form games exploring recommendation algorithms, echo chambers, and algorithmic bias through play, iteration, and weekly playtests.

Rapid design and technical iteration

Coursework Prototypes

A set of quick prototypes, including an endless runner, used to explore player agency, balancing, and tighter feedback loops.
