03 / About

Martin Schiller

Software & systems architect

I’m a German software and DevOps engineer, working remotely from Asunción, Paraguay, with hours that overlap European and US teams. Since 2021 I’ve worked freelance for German and international clients, from requirements to deployment and maintenance.

Alongside client work, I build open-source tools: Ziran, a programming language; Kryon, a UI library; and apps such as Inner Breeze and Werkzeug.
