About

Me

I am a software engineer who enjoys solving problems — the kind where the requirements are unclear, the tradeoffs matter, and the right answer isn't obvious until you've asked the right questions.

I try to think carefully before acting, and I care about getting things right, not just getting them done. A good solution, to me, is one that is simple enough to be understood and solid enough to be trusted.

That way of thinking didn't come from a textbook. There have been periods in my life where the ground disappeared and I had to learn what I was made of. I didn't come out of those times with answers — but I came out with a different relationship to difficulty. One that doesn't flinch from it, and doesn't pretend it isn't there. I think that's just who I am now.
