About

Hi, I'm Lee.

I'm an engineer, builder, and writer focused on AI and agent technologies. This blog is where I document what I’m learning, building, and thinking about—especially around harness engineering, intelligent agent systems, and the practical logic behind AI agents.

I'm particularly interested in how to make AI systems more useful in real products: not just by improving model capabilities, but by designing better scaffolding, better workflows, and better interfaces around them. That’s why I care deeply about harness engineering—the layer that turns raw model intelligence into something reliable, steerable, and genuinely valuable.

Before focusing on AI, I built products with a strong front-end full-stack foundation in React, TypeScript, and Node.js. That background still shapes how I approach AI today: from both an engineering and product perspective, with an emphasis on clarity, usability, and practical implementation.

This blog is a place for technical notes, experiments, architecture ideas, and personal reflections on building in the age of AI agents. If you're interested in practical AI systems, agent design, and engineering-first thinking, you'll probably feel at home here.
