About
About me
I am a California-based software engineer with experience across healthcare, research, databases, fintech, and small businesses. I’m comfortable moving across the stack when that’s what the problem requires—from talking with users and designing an API to building the interface, deploying it, and documenting the result.
I am especially interested in forward-deployed work where learning a customer’s domain is as important as writing the software.
