What I'm looking for

I'm looking to build elegant, user-friendly software where I can own quality end to end, solve complex problems with simple solutions, collaborate in a fast-paced agile environment, and keep learning from new tools and perspectives.

At Optum, I build generative user experiences with LLMs and prompt engineering, and designed microservices that helped support a threefold increase in customers across five states. I also implemented customer-facing UIs that reduced bad-input risk by 95%.

Previously at Xactware, I modernized insurance software used by 80% of U.S. claim adjusters, raised test coverage from 20% to 85%, and cut test execution time by 90%. I care deeply about software craftsmanship, user experience, thoughtful code review, and finding simple solutions to complex problems.
