I have a Bachelor's Degree in Computer Science and work as an IT Specialist.

I have created pseudoprime and prime proving programs using C and GMP:

- MPZ APRCL: https://sourceforge.net/projects/mpzaprcl/
- MPZ APRCL32 (for 32 bit machines): https://sourceforge.net/projects/mpzaprcl32/files/
- MPZ PRP: http://sourceforge.net/projects/mpzprp/

I have helped with the development of GMP-ECM: https://gforge.inria.fr/projects/ecm/ I have helped with the development of MSIEVE: https://sourceforge.net/projects/msieve/ I have helped with the development of YAFU: https://sourceforge.net/projects/yafu/

I have added my APRCL prime proving routine to the above three projects. I have helped find Brilliant Numbers: https://www.alpertron.com.ar/BRILLIANT.HTM I have factored several terms in the Home Prime 49 sequence: http://www.worldofnumbers.com/topic1.htm I have helped with the double-checking effort verifying all base-2 pseudoprimes compiled by Jan Feitsma: http://www.janfeitsma.nl/math/psp2/index
