Think different
I love Apple — useful products with the highest possible quality. Hardware and software that stays easy to understand for everyone.
// aboutChristian Koch
Code. CRM. Data. 18+ years at the intersection of tech and real business goals.
Hey there — I'm Christian. >38, living in Berlin, happily married with two little ones. A motivated, hands-on developer with leadership experience and 18+ years at the intersection of code, CRM, and digital marketing. Always looking for the next challenge.
Grown up in Schleswig-Holstein, further shaped by hamburg & berlin based agencies, ended up in engineering. I love building technically clean solutions that actually move a marketing team or business forward. Websites, native apps, CRM journeys, data pipelines — all of it, as long as it creates impact.

A bit more about me.
The professional side is only half the story — here is what shapes how I work and recharge.
The nerd
Born in 1985. Retail apprenticeship, then ~20 years coding in private and 18+ years professionally. Passionate about software for the web and Apple platforms.
The boarder
Snowboarding is one of the coolest sports, ever. Two weeks in the mountains clears the mind completely.
The captain
When the sun is out and time allows, I'm on a timeless boat trip on the beautiful lakes around Berlin.
The family guy
Happily married with two lovely little ones. I love spending as much time as possible playing with them.

Out of the IDE.
When I'm not deep in the tunnel or pairing with an AI CLI, I'm outside — preferably somewhere with water & with my kids. Berlin is home, but the best ideas usually arrive when I step away from the screen for a bit.

// principlesHow I work
Three principles
Pragmatic
Clean architecture, but no over-engineering. Ship what helps — not what impresses.
Data-driven
Brought from marketing & CRM: every decision should be measurable.
Modern, but honest
Current stacks (Next.js, Sanity, Vercel) yes — but only when they actually benefit the project.
