04 / A little more human
I like complicated, practical problems—the kind where the spreadsheet, the customer, and the code all have to agree.
That perspective comes from working across commercial real estate, product strategy, design, development, and marketing. I care about useful software, direct communication, and work that survives contact with the real world.
