Back to original languageAbout George
Senior Backend Developer with over 10 years of experience in developing and modernizing enterprise systems, primarily in the insurance and telecommunications sectors.
My focus is on backend development with Java and Spring Boot, complemented by practical experience with Kotlin – from scalable microservices and event-driven architectures to REST/SOAP integrations and the rebuilding of existing legacy systems. I work test-driven, value clean, maintainable code, and can quickly find my way around complex, established system landscapes.
In recent years, I have worked for several major German clients, both remotely and on-site, and communicate fluently in German (B2-C1) and English.
I work as a freelancer on a B2B basis. Invoicing is done via intra-community invoice using the reverse charge mechanism – uncomplicated for clients within the EU. I prefer remote assignments, with a willingness to attend occasional on-site appointments.
