Summary

I'm a product-minded software engineer who loves building things that make a real impact. Over the last ten years I've worked across web, backend, and native iOS at PlayStation, CrossFit, Stanford Health Care, and now Archer Aviation, and I've been lucky to work on some genuinely cool things along the way. Remote since 2018.
