Hi, I'm Alex (short for Alexander). I'm an iOS engineer at Automattic, working on Pocket Casts. I focus on performance, networking, and developer tools.

I built Nuke, an image loading system and Pulse, a network logger that works like Safari Web Inspector for native apps.

I write at kean.blog, mostly about Swift, SwiftUI, and performance.

Find me on Mastodon. Questions about Nuke or Pulse are best asked in their Discussions (Nuke, Pulse). If my work helps you, you can sponsor it.
