About me

Cyrill Zenkner

Private software developer from Germany — focused on clean code and software that works long-term.

Hi, I'm Cyrill.

I develop software because I love it. As a private individual, I build web applications, REST APIs and Android apps that real users use every day.

I think in architectures first, then in code. Before a single line is written, I consider how the solution should be maintainable, scalable and secure.

I work fully remote and manage my projects independently — from the database to the backend server to the frontend. No vendor lock-in, full control.

How I work

Transparent: Clear communication, regular updates.
Structured: Clean codebase, documented API, traceable decisions.
Long-term thinking: Code I'll still maintain in 2 years — no throwaway architecture.
Security-conscious: HTTPS, JWT, CSRF, rate limiting, hashed passwords — from day one.
