Sean Denton β the whole engineering department in one process. Systems from nothing to production: rockets, drive-thrus, hospitals, tractors. It's just me. That's the point.
π§ sean@sometimescreekventures.comπ rocket_data.txtBuilt the backend that ingests and processes Blue Originβs proprietary rocket test telemetry β real-time, large-scale, locked down.
π a_drive_thru_that_listens.txtR&D for Chick-fil-A: a voice-ordering system built in Swift on OpenAI and open-source LLMs, backend on Kubernetes β plus AI and VR prototypes for visualizing the store itself.
π human_hearts.txtA HIPAA cardiovascular remote-monitoring platform: five production Go services, device telemetry streaming through Redis hot storage into S3 archive, live clinical dashboards β designed, built, and operated in production alone. Deploys never blip a live monitoring session.
π the_36_second_request.txtA 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 β proven against baselines before every merge.
π 220_days_43.txtA client had a 220-dev-day estimate on the table. Audited what already existed before writing anything new β the real number was 23β43 days, validated by their own engineers.
π a_fortune_5_paved_road.txtAt CVS Health, leading the squad building the platform that provisions Google Cloud services with zero manual steps β security by default, 15+ engineers shipping it.
π the_fbi_is_on_line_one.txtFor CLEAR: the microservice line that registers travelers for TSA PreCheck, integrating with the FBI through a third-party vendor β deployed to AWS GovCloud.
π fracking_pumps_over_rs_232.txtPetroleum engineer by degree, so: rescued a buggy fracking-truck pump-control system β rewrote the Java agents talking to hardware over UDP, RS-232, and TCP.
π tractors_on_the_internet.txtGrain carts run embedded Linux with no connectivity β so built the iOS app that finds them over Bluetooth LE and shares the iPadβs connection with the tractor.
π radios_for_soldiers.txtFor Harris: the app a soldier uses to configure a truckload of military radios at once instead of one at a time β wrote the entire UI.
π 250_000_players.txtAs CTO of a gaming startup, took a prototype to production: a real-time multiplayer social game sustaining 250K+ users and hundreds of simultaneous games.
π survives_aws_going_down.txtFor Comcast: a device-telemetry microservice designed to finish its job even while the cloud under it is failing β plus CI/CD where entire environments are created and destroyed in minutes.
π days_of_hr_work_one_click.txtFor Zappos: a one-source-of-truth system wiring HR, IT, payroll, and billing together β onboarding an employee went from days of emails to a single action.
π a_dungeon_crawler_over_sms.txtBuilt a serverless AI assistant that lives entirely in text messages β including a full roguelike dungeon crawler you play by SMS, powered by Claude on Amazon Bedrock.
π talking_instead_of_typing.txtBuilt and released blurt and yap: push-to-talk dictation for macOS and Linux that runs entirely on-device, sub-second, no cloud β because talking to AI is half the job now and typing is the bottleneck.
