Hi, I’m Ninja.
I build SaaS & software that ships.
Product-minded engineer working across the whole stack — web apps, APIs, backend systems, servers and the pipelines that hold it all together. If it needs to run in production, I can build it.
The short version, in code.
// about.js const developer = { name: "Ninja", role: "Full-Stack Engineer / SaaS Builder", focus: ["SaaS products", "backend systems", "APIs", "servers", "automation"], approach: "idea → architecture → shipped, production-ready code", contact: { whatsapp: "+49 155 10836996", email: "nightninja.de@gmail.com" }, status: "available for new projects" };
Tools I reach for daily.
A pragmatic toolkit for shipping real products — not just demos.
What I can build for you.
From a first prototype to a system running your business.
SaaS Development
Multi-tenant web apps, subscriptions, billing and dashboards built to actually launch.
Backend & Server Architecture
Designing and running the servers, databases and infrastructure behind your product.
API & Integrations
Connecting your tools with clean, documented APIs and reliable third-party integrations.
Automation & Scripts
Removing repetitive manual work with scripts, bots and background jobs that just run.
Cloud & DevOps
Deployment pipelines, containerization and monitoring so your server stays online.
Full-Stack Web Apps
End-to-end products — frontend, backend and everything wired together correctly.
Let’s build something.
