Software solutions with Open Source

/images/telle-logo.svg
I develop professional software solutions for research and industry in the STEM field (Science, Technology, Engineering, and Mathematics) based on open source components — in particular with C++ and Fortran as well as the wxWidgets library for cross-platform applications.

My focus is on the adaptation, extension, and integration of existing components, especially in the following areas:

/images/glassball-blue.svg Databases, in particular SQLite with encryption
/images/glassball-green.svg PDF generation and reporting
/images/glassball-yellow.svg Diagrams and visualizations
/images/glassball-red.svg 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.
