Chris Risio

I'm Chris, a recent CS grad who's been shipping software professionally since I was nineteen. I care about taste, the kind that quietly compounds: well-named functions, fewer abstractions, interfaces a person can keep in their head, products that feel made by someone instead of assembled.

For the last three years I've been the engineer founders call when the prototype isn't enough anymore. When it has to handle real users, real money, real edge cases. I work fast, ask the boring questions, and write code I'd be willing to own at three in the morning.

I'm taking on a small number of contracts and at most one founding-engineer role this year. If you're building something that has to be good, not just functional. Let's talk.

Let's build something good.

Pick whichever's easiest. Tell me what you're building, what hurts about it, and when you need it. I'll write back within a day with an honest answer.
