Freelancer profile translated to English.

Description

I am a Full Stack Engineer with over 15 years of experience in developing and operating complex web and platform solutions.

My focus is on API-first architectures and stable backend systems, particularly with PHP/Symfony and Node.js, combined with modern frontends like Vue.js or React. I prefer working in product-oriented environments where sustainable architecture, clear interfaces, and long-term maintainability play a central role.

Throughout my projects, I have taken responsibility for the entire lifecycle of web platforms – from architecture and technology decisions, through CI/CD pipelines and container deployments, to the stable operation of production systems.

Typical projects and topics:

• API-driven product platforms

• complex shop and platform architectures

• scalable backend services and microservices

• CI/CD automation and containerized infrastructure

Technological focus:

Backend

PHP (Symfony), Node.js, NestJS, REST APIs, Microservices

Frontend

Vue.js, TypeScript, React, Next.js / Nuxt

Infrastructure

Docker, CI/CD, Linux Servers, PostgreSQL / MongoDB

I am currently looking for a remote or hybrid position (max. 1 on-site day per week within the Düsseldorf area) in a product-oriented team where technical quality, clear architecture, and long-term solutions are valued.
