About
I'm an engineer who builds AI agents, developer tools, and the products around them. I trained as a cognitive psychologist (Ph.D., Johns Hopkins), and I hold one stubborn belief: intelligence is an algorithm, and a mind is defined by what it does, not what it's made of. So building machine intelligence and understanding human intelligence are, to me, the same project. I write here about both — agents, the craft of building software, and how minds and machines reason, remember, and build.

Resume of Failures
This is a list of what I have tried during my journey. It is a running list of my failures during my journey. The idea is inspired by Prof. Johannes Haushofer. I was trying to summarize all of them, but some may have eluded my memory. I will keep maintaining this list, so future failures will be recorded and updated. You are welcome to come back and check my latest failures.
