Software Engineer
From approved designs to dependable deployments
I'm Christoph Astner, a German backend-leaning engineer who turns finished web designs into resilient applications and headless commerce solutions without compromising performance, maintainability, or infrastructure readiness.
About
Engineering reliable solutions with an eye for detail
My career started as an electroinstallation technician before moving into CNC machining and eventually software engineering. That hands-on background shaped the way I deliver pragmatic, production-ready software that keeps infrastructure, networking, and operations in mind from day one.
I don't create visual designs, but I love partnering with designers and stakeholders to turn approved concepts into maintainable applications and headless shop frontends. Native German speaker, fluent in English, and always focused on clear communication across distributed teams.
