I make products, and the part I enjoy most is the end, when everything is in place and the thing is simply pleasant to use. Most of what I do is aimed at getting there.
iOS apps are my biggest passion. I care a lot about UI and about how an app feels under your fingers, and my attention to detail borders on excessive. I notice when an animation is slightly off or a tap responds a moment late, and I keep working on it until it's right.
I also like being part of the whole product. I've worked on all of it from the ground up: infrastructure, backend, web and mobile, and then the landing page, analytics and marketing after launch. Besides Swift, I write a lot of TypeScript and Go.
