Hi, I'm Sergej Steinsiek. Full-Stack Developer.
I build robust backends, design efficient RESTful APIs, and craft dynamic, user-friendly frontends-delivering complete and scalable web solutions.
About Me
As a Full-Stack Developer based in Germany, I specialize in architecting and implementing complete web and desktop solutions. I have a strong passion for designing efficient RESTful APIs, building robust backend systems, and creating responsive, user-friendly interfaces.
With a focus on clean, maintainable, and scalable code, I enjoy tackling both backend logic and frontend interactivity. My technology stack includes JavaScript, TypeScript, Java, C#, Node.js, .NET, Delphi, and modern frontend frameworks like Vue (with Vuetify) and React—often styled with Tailwind CSS.
I’m always eager to explore new technologies and best practices to improve development workflows and deliver high-quality software.
