Software solutions with Open Source
My focus is on the adaptation, extension, and integration of existing components, especially in the following areas:
Databases, in particular SQLite with encryption
PDF generation and reporting
Diagrams and visualizations
Mathematical modeling and numerical methods
In addition to technical implementation, I am happy to advise and support you in using these technologies efficiently — from design and integration to customization and further development of individual modules.
Technically sound. Open in implementation. Reliable in collaboration.

Links to update notices for my open source components or to general blog posts can be found below:
Release of wxSQLite3 Version 5.0.1
Ulrich Telle published on August 12, 2026wxSQLite3, an interface to SQLite databases for wxWidgets-based applications, has been available for over 20 years. During this time, the C++ programming language in particular has evolved significantly, making it high time to modernize the interface and adapt it to some of the new features in C++.
Release of SQLite3MC Version 2.5.0
Ulrich Telle published on August 2, 2026Version 2.5.0 of the SQLite encryption extension SQLite3 Multiple Ciphers, based on SQLite 3.53.4, has been released.
Since the changes made for this version — at least for now — have no impact on the functionality of the dependent components wxSQLite3, SQLite3MC-NuGet, and apsw-sqlite3mc, these components have not been updated, as is usually the case.
Release of SQLite3MC Version 2.4.0
Ulrich Telle published on July 28, 2026Version 2.4.0 of the SQLite encryption extension SQLite3 Multiple Ciphers, based on SQLite 3.53.4, has been released.
In this context, the components SQLite3MC-NuGet, wxSQLite3, and apsw-sqlite3mc have also been updated.
Open Source developments
My open source components are continuously being developed to meet new requirements, fix bugs where necessary, and offer practical solutions.
