Systems, scripts & the curious space between.
I’m a senior enterprise endpoint management engineer working across Apple platforms, identity, and automation—and the builder of DC Pulse, a native iPhone app now in TestFlight.

The work
Engineering for the real world.
Thousands of devices. Different people, priorities, and constraints. I like finding the structure that makes all of it easier to operate.
Scripts that hold up
Turning repetitive work into readable, logged, testable automation that teammates can understand and safely operate.
Identity that feels natural
Exploring Platform SSO and modern authentication without losing sight of the person sitting in front of the Mac.
Product engineering in Xcode
Taking DC Pulse from an idea to TestFlight—working across SwiftUI, public-data APIs, product design, privacy, testing, and release readiness.

Field notes
An idea became a real app.
DC Pulse started as a way to learn Xcode. Building it has meant learning the whole path from raw public data to a product running on someone else’s phone.
DC Pulse
A native, map-forward iPhone app that turns DC’s public 311 and permit data into a clearer view of what’s changing nearby. It now spans live data integrations, saved places, watches, local notifications, an on-device 311 drafting flow, and a real App Store release process.

DC Pulse has become a practical education in much more than SwiftUI: GIS data, resilient networking, privacy-minded architecture, accessibility, testing, product decisions, TestFlight feedback, and the discipline of getting software ready for other people.
AI as a capable collaborator
Using AI across research, architecture, implementation, testing, troubleshooting, and documentation—while keeping product judgment, verification, and responsibility firmly human.
Calm systems win
The best infrastructure—and the best products—are legible, staged, reversible, and boring in exactly the right ways.
A wider frame of reference
A family trip to Japan brought new perspective through Tokyo’s transit, density, design, and everyday systems—and another reminder that some of the best learning happens by experiencing how other places work.
About
Technical by trade.
Curious by nature.
I care about well-managed Macs, thoughtful automation, and documentation that respects the next person who has to understand it. But work is only one outlet for the way my mind works. I’m happiest following a question far enough to see what connects—whether that means experimenting with self-hosting and mesh radio, digging into a new scientific question, or building a small app just to make an idea tangible.
That curiosity reaches well beyond technology. I’m drawn to science—especially physics, astronomy, evolution, and the complex systems that turn simple rules into surprising behavior. I like the big questions, the strange edge cases, and the moment when a good explanation changes how the everyday world looks. More than anything, I enjoy learning across disciplines, making useful things, and trading ideas with people who are curious about something themselves.

Curious about something? I probably am too.
Tech, science, a half-formed idea, or whatever has your attention lately—I’m always glad to hear a thoughtful take or an interesting question.
