I grew up fascinated by how cities move — the rhythm of streets, the way a neighborhood reveals itself when you walk it instead of drive it.

That obsession led me to build Le Walk, an app that narrates your surroundings in real time as you explore on foot. It uses AI to weave together history, architecture, culture, and local lore — delivered through your headphones, personalized to where you are and what you're curious about. Think of it as a brilliant local friend who never runs out of things to point out.

Before Le Walk, I was on the engineering team at Uber working on self-driving vehicles in Pittsburgh and San Francisco — building perception and planning systems for autonomous cars.

Before that, I studied computer science and spent time building things at the intersection of software and the physical world.
