About

I'm a senior React engineer who cares about craft — both the code and the experience it creates. Over the past seven years I've worked across the stack at companies like Amazon Web Services, Path Robotics, and Comcast, building interfaces that serve millions of users at a time.

I specialize in React and the modern JavaScript ecosystem, and I bring a strong sense of quality to everything I ship — from architecture decisions to the subtle interactions that make a UI feel right.

I'm also an early adopter of AI-native development workflows — using tools like Anthropic Claude and GitHub Copilot as genuine force multipliers for code quality, iteration speed, and documentation. It's changed how I build, and I think it's the direction serious engineering teams are heading.
