Products

This catalog includes professional-grade product work and independent lab projects. Everything here was designed, developed, and shipped by one person using AI as a multiplier, not a substitute for judgment.

The apps and systems show how I think about real-world product problems. The games and interactive experiments demonstrate technical depth, interaction design, tuning, performance, and end-to-end execution.
