About Gunther
I have a year-long experience as Oracle full stack developer and work with the Oracle database as since 1997. My focus is on data storage and processing, traditionally relational with the excellent Oracle database and with modern NoSQL concepts like Oracle NoSQL database and the development of web application with Oracle APEX. As a member of the German Oracle User Group I work there as a delegate and participate regularly as a speaker at the events of the DOAG.
