Full Stack Developer: Backend APIs, Integrations and Automation
Germany
English, Ukrainian, Russian, German
About me
I am a backend focused full stack developer working with Java, Spring Boot, Node.js, Python, Vue.js and PostgreSQL. I build production APIs, third party integrations, automation pipelines and browser extensions that remove manual, repetitive work.
I work daily on real production systems for automotive and industrial clients, so you get clean code and reliable delivery, not throwaway prototypes. Based in Germany (CET), I communicate clearly in English and German and I reply fast.
Tell me what you need built or automated, and I will give you a straight, honest plan with a realistic timeline.
