Product engineer with 10+ years of experience. I have built and operated 28 products end-to-end across product, engineering, design, and operations, and started Groundcode as a solo product studio in late 2025. I recently launched Engine Simulator, Kickflip Simulator, and Weapon Simulator 3D. I run Toss mini-apps and web products against real usage, retention, and unit-economics data, turning ideas across AI, utilities, and consumer apps into products that can be tested in the market.
