What I’m doing now

(This is a now page, and if you have your own site, you should make one, too.)

Updated 2026-11-08 from the Aarau region, Switzerland

Work. Since 2025 I’m a project manager at Alos Solution AG in Obfelden. I lead process automation projects with JobRouter and DocuWare, connect ERP systems like Microsoft Business Central, and bring language models into business processes. I still write a lot of the code myself.

Ruby. 2026 has been a busy year for my open-source work:

• IronRuby 4.0: Ruby 4.0 on .NET 8, a revived fork with prism as its parser.
• Ruboto with JRuby 10: Android apps in Ruby again, running on a Frameo photo frame and Wear OS watches.
• OCRAN, clogs, ruby_pptx and other gems, plus a faster File.stat on Windows in CRuby itself.
• Chunky Bacon: a free Ruby course in German and English that runs in the browser.

In April I was at RubyKaigi 2026 in Hakodate and met Matz right after he unveiled Spinel in his keynote. On 19 and 20 November I’ll be at Helvetic Ruby 2026 in Zurich. Say hello if you’re there!

Ruby in Switzerland. I think Ruby deserves more attention here, so I keep a page on Ruby in Switzerland with the companies, events and arguments for CTOs.

Reading. Café Torunka by Satoshi Yagisawa, and Grenzen setzen by Jan-Uwe Rogge.

Earlier. After 9 years in Miyazaki, Japan, we moved back to Switzerland in 2024. That year I worked on Hitobito for the Swiss Alpine Club, gave a talk about ruby.wasm at RubyKaigi 2024 and went to RubyWorld 2024.
