## Projects

- [Ground-station observability](https://tyleryouk.com/resume.pdf) (2025–now): A Python Prometheus exporter turning four classes of ground-equipment health into 27 metric families at 99.97% scrape availability, on a stack of about 440,000 active series.
- [Satellite tasking API](https://tyleryouk.com/resume.pdf) (2026–now): A FastAPI and PostgreSQL endpoint that schedules both geostationary and low-orbit observations, with a per-antenna work queue and a generated OpenAPI contract of 19 operations.
- [An agent fleet on one server](https://tyleryouk.com/writing/architecture) (2026): Claude Code agents on a server I own, each its own Linux user, each task its own systemd unit, dispatched under one lock so no task runs twice.
- [dispatch-runtime](https://github.com/utopia-models/dispatch-runtime) (2026): The fleet's whole runtime: two shell scripts and systemd, and the flock that closed a 26 second race between agents running as different Unix users.
- [google-calendar-mcp](https://github.com/kxagent/google-calendar-mcp) (2025): An MCP server that lets Claude read and manage Google Calendar: events, calendars, free/busy.
- [opensky-mcp](https://github.com/kxagent/opensky-mcp-public) (2025): An MCP server for live aircraft tracking over the OpenSky Network API.
- [dmv-hackathon](https://github.com/utopia-models/dmv-hackathon) (2026): One Next.js app built in a day at the DMV Hackathon in Arlington, VA.
- [Flappy Fall](https://github.com/kxagent/flappy-fall) (2015): My second app on the App Store, in Objective-C.
