Freelancer profile translated to English.

Description

Full-Stack Developer with over 10 years of experience — from API to deployment. With k:ey software, I pursue a clear goal: software that truly belongs to its customers. Development from Germany, hosting on own hardware in German data centers, GDPR-compliant without compromise. No hidden outsourcing to US cloud infrastructures — because those who don't control their data don't control their business either.

I build web, desktop, and mobile solutions for startups and small businesses — and host them directly if desired: on root servers in German data centers, completely under your control. Stack: .NET (Blazor, Razor, MAUI, WPF, Avalonia, WinUI), Vue.js, Angular, Astro, TypeScript, Docker, CI/CD, MySQL, PostgreSQL, MS-SQL, and Microsoft Azure.
