Back to original languageAbout David
I develop web applications with PHP, MySQL, and JavaScript. I built AnfrageBox.de independently, a B2B SaaS platform with Stripe integration, WhatsApp API, XRechnung 3.0, and a digital customer portal. I work fast, deliver clean code, and communicate directly. No overhead, no agency behind it. If you have a specific project, I will implement it.
