About

By Danny Krämer

I am Danny Krämer, a full-stack developer based in Germany. I spend most of my working hours on e-commerce systems — mainly SAP Commerce Cloud — and I am deeply interested in how AI is reshaping the way we build software.

This site, d9r, is a personal corner for writing, side projects, and experiments. The name is short for my name, like A16z or K8s, you know?!

Skills & Tech Stack

Day-to-day

  • Java / Spring — enterprise backends, SAP Commerce
  • TypeScript / Vue / Nuxt / React / Next — modern web UIs

Exploring

  • Rust, WebAssembly, ML/AI engineering, and security

Current Focus

Right now I am focused on a few things:

  • Reading up on Rust and WebAssembly as paths toward lower-level, higher-performance web work
  • Thinking through what "augmented development" really means for the profession
  • Building small side projects to put ideas into practice

See my Now page for a more detailed and up-to-date snapshot.

  • GitHub — code and open-source projects
  • X - not really active there
  • Mastodon - for the geeks
  • Bluesky - there since the Twitter exodus
  • Email — say hello
