About
Jaesung Lee
Seoul, Korea. Quant trader turned AI explorer.
9+ years building real-time trading systems in crypto — HFT, arbitrage, market making. Now shipping one project every day to find what's worth building for a lifetime.
Manifesto
In the age of AI, the cost of building has collapsed to near zero. The scarce resource is no longer execution — it's knowing what to build.
I build every day. Not to pad a GitHub profile, but because systematic exploration is the only reliable way to find what's worth a lifetime of deep work.
Think of it like a build order in StarCraft: the opening moves aren't the game — they're how you discover the game.

Gaming
League of Legends
Long-time player since Season 1. Macro-oriented playstyle — map control and objective trading over mechanics.
Hearthstone
Deckbuilding as optimization. Understanding meta shifts and expected value — same lens as trading.
Teamfight Tactics
Economy management, pivot decisions, and probabilistic thinking. The poker of auto-battlers.
Games are how I think about systems. Every competitive game is a decision engine — resource allocation, incomplete information, adaptation under pressure.
