FAA private pilot, in training.
Roughly 38 hours logged in a Cessna 172. Boulder Municipal as a home field, mountain training in the spring. Checkride scheduled for summer 2026.

About
Eleven years at Apple. Now founding from Boulder.
I work where product judgment, systems engineering, and company formation have to move together. Most of what I’ve shipped sat under that overlap — first as an engineer, then as a lead, now as a founder.
I joined Apple in 2014 out of a one-summer internship and spent five years on Application Frameworks. The work was depth-of-stack platform work — long-running services and per-app sandbox primitives — and it taught me to read a system by its boundaries, not its features.
In 2020 I moved to a new platform that didn’t yet have a name in public. I led the visionOS System UI team from three engineers to roughly thirty across the launch window. We shipped the chrome the operating system and every visionOS app rendered against, and a stability release after that. Six patents came out of the work, granted or pending.
I left Apple in 2025 to start Calderone Technologies, a small technology holding in Boulder. Two products are in flight: CodePulse, an engineering-analytics product in private alpha with two design partners; and a voice and gaze input layer for iOS and macOS, pre-product. Both are built against the same conviction — that a product that earns its place reads as inevitable, and a product that doesn’t reads as noise.
Around the work I am learning to fly (FAA private pilot, ~38 hours logged), I keep a small KiCad bench, and there’s an old Bandcamp page from before this work.
How I work
Four habits worth writing down.
01
Hold the surface count small.
Every additional thing on screen is a thing you have to maintain, calibrate, and explain. Less is the constraint, not the goal.
02
Hire against the work, not the org chart.
Headcount that isn't anchored to a surface drifts. Surfaces that aren't owned by a person rot. Both are the same problem.
03
Ship the SDK before the product.
If the primitive is right, other teams will find uses I haven't thought of. If the primitive is wrong, my product won't save it.
04
Write it down before you ship it.
The decision that can't survive a paragraph hasn't survived the meeting. Memos are cheaper than launches.
Practices
Three things I do around the work.
A KiCad bench in the basement.
Small two-layer boards. ESP32 e-paper desk object on Rev C. The work is slower than software and rewards patience in ways that translate.
Rev C · CERN-OHL-S · 2024 —A Bandcamp page from 2017.
Three EPs of slow ambient guitar from a previous life. Not active; not coming down. Useful as a reminder that I once shipped things without committees.
