Full-Stack Engineering/AI Systems/Quantitative Tooling
Hi! I'm Cody Jung —Building software where AI meets real systems.
Business + Data Science at UC Berkeley Haas. I build production-minded AI tools: RL simulation environments, backtesting systems, market intelligence dashboards, and full-stack data products.

About
I’m Cody Jung, studying Business + Data Science at UC Berkeley Haas. I build full-stack systems around AI workflows, reinforcement learning, and quantitative research tools — usually with Python, TypeScript, FastAPI, Next.js, PostgreSQL, and Redis. Recently, I’ve been focused on moving from AI-assisted products toward deeper ML systems: CombatRL, a deterministic tactical arena for training and evaluating RL agents; an event-driven backtesting lab with an AI research copilot; and a prediction-market intelligence platform combining market data, sentiment, and anomaly detection. I’m most interested in tools that make intelligent systems usable in practice: structured inputs, reproducible evaluation, clear assumptions, and workflows that can survive outside a demo.
