Summary

Since 1989 I have been involved in professional software development. My main focus is on one hand the design and development of native iOS applications using Swift and SwiftUI and on the other hand the development of database-based graphical applications with C#/Delphi/Java in client/server as well as web and multi-tier architectures based on SOAP or REST web services. Designing and implementing the related SOAP/REST web services is part of my portfolio, as is developing or optimizing database procedures in SQL and PL/SQL for efficient server-side processing of large data volumes. In most projects, I have been part of an agile SCRUM team.
