Career
Over 15 years I've specialized in platform-level services at the boundary of mobile apps and distributed infrastructure: real-time event delivery, notification pipelines, and backend-for-frontend systems. At SimpliSafe I founded and led the App Services team from the ground up as a player-coach, then intentionally stepped back into a hands-on individual-contributor role to focus on what I love most: system design, architecture, and solving hard distributed-systems problems alongside a great team, but most importantly, solving real problems for real people. The services I've built and operate scaled with the company from ~1M customers to 5M+ people protected, moving tens of millions of real-time events and notifications a day.
MoreLess
I'm an agilist at heart: extreme programming, test-driven development, and rapid feedback through continuous delivery. I treat what I don't know as an opportunity to learn, I openly mentor and share what I've accrued, and I expect the same generosity back from the people I work with. Lately that curiosity has extended to agentic AI tooling and decentralized protocols.

FoV II is finally out on Bandcamp! I know what I’m listening to all day.
↗I’ve officially accepted a new position. Seven years I’ve been at the current company, my longest stretch so far. It’s incredibly bittersweet, nearly everyone there I’ve worked with has been fantastic, but I must leave. Excited to take on new challenges at the end of the month!
↗channeling the nervous energy into chores and the most annoying king gizz playlist I could think to make: music.apple.com/us/playlist/...

Spending the weekend in California for Blizzcon! Very excited, seeing some friends I haven’t seen since the last one I attended in ‘19. Not to mention it will be a much needed break.
↗iPhone Duo looks neat! I’m a southpaw though, so a little apprehensive about the right-mounted control cluster. Unlocking with Touch ID seems like it’d be a little awkward. Maybe I’ll test drive it in-store one of these days.
↗November 5th for the Ocarina of Time remake!! Let’s goooo, it looks nice. Seems like they maybe aren’t doing anything unexpected with the story? 🤔
↗new Vulfpeck single day let’s goooo
Seems like a thrash kind of day. Doing morning routines to PetroDragonic Apocalypse and feeling ready to gooooo!
