GitHub numbers on my PanelOS screen: commits and active days over the last 12 monthsMy contribution grid for the last weeks
Active days, repos, Apify actors, last syncNow shipping: TinyRex, tender scrapers on Apify
LinkedInGitHubdev.tohatt.at

Building banking systems by day, open-source tools by night.

The screen is PanelOS, the Windows app I'm building for the small USB screens people put in PC cases. Here it shows my GitHub numbers instead of CPU temps, rendered every morning with the app's own theme code. The bottom row links out.

Support my open-source work: get a SkinToScan pack
If you find this useful, you can support me by getting a SkinToScan pack, my other project. It's a one-time purchase that directly funds my open-source work.

What I run

hatt.at homepage

HATT
My product studio. Focused software for operations, funding and health work, the kind that's too complex to live in spreadsheets.

 skintoscan.com homepage

Skin to Scan
Upload a photo of a mole and a CNN gives you a screening result. It's for awareness, not a diagnosis, and it tells you that. I founded it and built it.

On the side

  • TinyRex: a dozen pay-per-result scrapers on Apify for job boards, Shopify and WooCommerce stores, and EU and US tenders. Guides and examples.
  • PanelOS: the app on that screen. It drives the small USB screens people put in PC cases: temps, load, and whatever Spotify is playing.

 behave terminal demo: probing jq and diffing gojq

behave stars
