The small things compound.
We sweat the details so you don't notice them. The hours spent on craft become the seconds you don't think about.

Hello, I'm Casey.
Welcome — glad you came by.
Below: what I'm building, where I've been, and how to find me.

What drives this.
[02]
Software you'd want to live with.
Most apps demand your attention. We try to build the kind you'd happily install again next year.
[03]
For the moments worth keeping.
We make tools for the days you'll remember — not the ones that blur. Apps for the journey, for travellers of all ages.
[04]
Care, made visible.
Sophistication, in the end, is what's left after everything else is removed.

How I got here.
I'm Casey O'Mara — VP of Platform & Cloud Engineering at Oracle Cloud Infrastructure, where I lead global platform engineering across enterprise cloud, security, and DevOps.
More than two decades of building and scaling cloud-native platforms — through JFrog's IPO, across hyperscalers, inside Fortune 100 enterprises. The work has touched AWS, Azure, and Google Cloud as much as OCI.
I served on the Cloud Native Computing Foundation governing board representing JFrog through their IPO years. I hold five patents, all in AI.
Before any of it, I served in the United States Air Force. Honorably discharged. The discipline and systems thinking I picked up there still shape how I approach the work.
I live in Cape Cod, Massachusetts.
NimbleZen is what I'm making on my own time — QueXplorer right now, plus notes on AI and the craft of making things.

Nimble
Move at the speed of decisions.
Light kit, sharp ideas, real momentum. The structure is the speed.
Zen
Three questions, then we go.
Does it work. Does it feel right. Does it fit the day you'll actually use it on.
NimbleZen
Both at once. The synthesis.
Speed without rushed. Care without slow. Built deliberately, shipped often.

App · iOS & Android
QueXplorer
A companion for theme park days that turns the slow parts into the good parts. Live waits, queue-side quests, three mascots.

The work behind the work — what AI is making possible, what it isn't, the craft choices that went into a release.
