About

Full-stack engineer at Letter AI, which is a polite way of saying I'll touch any part of the stack if it makes the product better. Confession - I don't love my code. I don't love my tools. I love the moment everything converges, when the thing you built does the thing it was supposed to do, for the person it was supposed to help. That's what keeps me up. Started a blog at 14, tinkered with everything since, and somewhere along the way figured out I'm a product/customer person who happens to write code (scalable and clean code, for the record, I just won't lead with it). Mostly startup-shaped career, with one stop at Walmart search team as an IC to keep me honest. I strive to excel at any work I do, because I think with self love you love everything you do even work and I hate half-assing anything, especially work, whether that's being the school cafeteria cashier the kids genuinely liked, or a founding engineer at a Series B startup
