I'm Tarek Rached. I like to build things, and to use numbers to create pictures of the material world.

You can find me on Github and LinkedIn.

Tarek's Head

I'm Head of Data Platform at Samsara: the sensors and software that fleets use to keep vehicles tracked, drivers safe, and operations running. Before that I was Senior Director, Data Platform at Equilibrium Energy, building AI-native data infrastructure where LLMs and agents are first-class consumers alongside humans. Earlier, I led a data applications team in Apple's AI/ML org and built the Algo UI team at Stitch Fix. You can still check out the Algorithms Tour if you're curious.

Projects

Nights-and-weekends builds, all on GitHub:

  • esphome-sram-axs: SRAM AXS (eTap) battery levels in Home Assistant, decoded on the ESP32; no pairing, no app.
  • pbz: command-line toolkit for Pixelblaze LED controllers, built for some LED strips at home.
  • chartsam: NOAA chart 18649 (Entrance to San Francisco Bay) as an offline PWA with live GPS position, for when I'm out on the water; built because the official PDF is big enough to reliably crash an iPhone viewer.
  • eat-my-shorts: when do I have to leave my desk to catch the train, and what time will I be home? Real-time BART departures as a home-screen PWA.
  • hot-tub-time-machine: water-chemistry tracker with a test wizard and dosing math.

Older: the Stitch Fix Algorithms Tour is still up, and still the thing I point people at first.
