Back to original languageAbout Kevin
I develop systems that work – reliably, scalable, and cleanly structured.
GitHub, GitLab, etc. on my portfolio: kevinpoppe.com
As a fullstack developer with a focus on **Next.js**, **Express**, and **TypeScript**, I build performant web applications that integrate seamlessly into complex infrastructures. My focus is on stability, maintainability, and efficiency – I think in systems, not in individual solutions.
I accompany projects from idea to deployment:Greenfield projects**, **CI/CD automation**, **performance optimization**, or the **introduction of modern development standards**. I use technologies such as **Docker(Swarm),Redis**, **PostgreSQL**, **Turborepo**, **Traefik**, and **Keycloak– precisely tailored to the respective use case.
I work **structured**, **pragmatically**, and **clean-code-oriented**. I first understand problems conceptually, reproduce them analytically, and develop sustainable solutions based on that. Colleagues describe me as a "performer with foresight" who consistently prioritizes code quality, automation, and maintainability.
Most recently, at Kupona and Urlaubsguru, I was instrumental in introducing Greenfield projects, CI/CD pipelines, and standardized development processes. The results:more stable deployments**, up to **150% more revenueper customer, and significantly **lower maintenance times**.
I strive for technical excellence - with solutions that work, grow, and remain economical
