Stefan

Hello.

My name is Stefan Sperber. I’m a Java backend engineer at Rakuten in Tokyo, Japan.


I work on applications that collect, process, and serve any amount of data. The code that I write is well-tested, and easy to understand.

For a list of open source projects that I’ve contributed to please see my GitHub. My profile on Linkedin has a detailed summary of my experience, and the technologies and methodologies that I’ve used. You can also contact me by email.
