Software Architect, COM, .NET and Smartcard based security specialist.
I've been working in the software industry since I graduated in Electrical and Electronics Engineering. I chose software because I preferred digital to analog.
I started to program with 6802 machine code and evolved to the current .NET technologies... that was a long way.
For more than 20 years I have always worked in technical positions as I simply like to get my hands dirty and crack my brain when things don't go right!
After 12 years in the smart card industry I can claim a strong knowledge in security solutions based on those really small computers!
I've been back into business to design the licensing system for the enterprise solution for Consistel using a .NET smart card (yes they can run .NET CLR!)
I'm currently designing a micro-payment solution using the NXP DESFire EV1 with the ACSO6 SAM of ACS. I can then add a full proficient expertise on those systems and NFC payments.
This technology being under strict NDA by NXP I cannot publish any related article about it, however I can provide professional consulting for it.
You can contact me for professional matter by using the forum or via my
LinkedIn profile.
