About

I'm Johannes Franz, a software engineer working on systems: storage engines, build tooling and the infrastructure underneath products. I like problems where correctness matters more than cleverness, and code that stays boring under load.

Away from the keyboard I photograph, mostly mountains and cities, mostly on foot. The photographs here are grouped into series, the way a survey groups its map sheets.

The best way to reach me is by email.

Names and titles are set in Young Serif by Bower House. Text is set in Schibsted Grotesk by Schibsted, and coordinates, dates and sizes in Geist Mono by Vercel. All three are open-source and served from this site.

The site is a static build made with Astro and hosted on Cloudflare Pages. It has no tracking and makes no third-party requests.

The number in the bottom-right corner of every page is that page's size: the HTML, styles, scripts and fonts, compressed the way they are served. It's measured after every build. Photographs are excluded, because they're the point.
