Rocket data
Built the backend that ingests and processes Blue Origin’s proprietary rocket test telemetry — real-time, large-scale, locked down.

quietly.
Sean Denton. One engineer. Twenty-plus years.
Nothing extra. Everything delivered.
The work
A drive-thru that listens
R&D for Chick-fil-A: a voice-ordering system built in Swift on OpenAI and open-source LLMs, backend on Kubernetes — plus AI and VR prototypes for visualizing the store itself.
Human hearts
A HIPAA cardiovascular remote-monitoring platform: five production Go services, device telemetry streaming through Redis hot storage into S3 archive, live clinical dashboards — designed, built, and operated in production alone. Deploys never blip a live monitoring session.
The 36-second request
A mobile-ordering API was timing out for one request in ten. Built the k6 load-test platform and Grafana observability from scratch, found the thread-pool starvation, and drove p95s from 36 seconds to 95 milliseconds — proven against baselines before every merge.
220 days → 43
A client had a 220-dev-day estimate on the table. Audited what already existed before writing anything new — the real number was 23–43 days, validated by their own engineers.
A Fortune-5 paved road
At CVS Health, leading the squad building the platform that provisions Google Cloud services with zero manual steps — security by default, 15+ engineers shipping it.
The FBI is on line one
For CLEAR: the microservice line that registers travelers for TSA PreCheck, integrating with the FBI through a third-party vendor — deployed to AWS GovCloud.
Fracking pumps over RS-232
Petroleum engineer by degree, so: rescued a buggy fracking-truck pump-control system — rewrote the Java agents talking to hardware over UDP, RS-232, and TCP.
Tractors on the internet
Grain carts run embedded Linux with no connectivity — so built the iOS app that finds them over Bluetooth LE and shares the iPad’s connection with the tractor.
Radios for soldiers
For Harris: the app a soldier uses to configure a truckload of military radios at once instead of one at a time — wrote the entire UI.
250,000 players
As CTO of a gaming startup, took a prototype to production: a real-time multiplayer social game sustaining 250K+ users and hundreds of simultaneous games.
Survives AWS going down
For Comcast: a device-telemetry microservice designed to finish its job even while the cloud under it is failing — plus CI/CD where entire environments are created and destroyed in minutes.
Days of HR work → one click
For Zappos: a one-source-of-truth system wiring HR, IT, payroll, and billing together — onboarding an employee went from days of emails to a single action.
A dungeon crawler over SMS
Built a serverless AI assistant that lives entirely in text messages — including a full roguelike dungeon crawler you play by SMS, powered by Claude on Amazon Bedrock.
Talking instead of typing
Built and released blurt and yap: push-to-talk dictation for macOS and Linux that runs entirely on-device, sub-second, no cloud — because talking to AI is half the job now and typing is the bottleneck.
The way
baselinechangeload testprovepromote
Measure before and after touching anything. Flag guesses as guesses.
AI-augmented delivery, with accountability: I direct the agents, run the tests, and own every commit.
Audit what exists before estimating what doesn’t.

The person
Petroleum engineer by degree — The University of Texas at Austin — twenty-plus years shipping software instead. CTO, principal architect, tech lead, and the contractor who arrives when it's on fire. A patent on browser-based content protection. Georgetown, Texas.
The company is named for the creek on the land: dry most of the year, running hard when the rain comes. Dormant channel. Full capacity on demand.
