About

I build tools at the intersection of AI, creative workflows, and automation. My focus is on thoughtful craftsmanship and real-world impact and usefulness over hype or revenue - turning ideas into software people genuinely value.

In my personal research, I explore computational models of learning and perception informed by neuroscience and evidence from animal and human behavior. My work focuses on architecture design, iterating on hypotheses and validating them through small, well‑scoped experimental setups.
