Wisnu Anggoro is a Microsoft Certified Professional in C# programming and an experienced C/C++ developer. He has been programming since he was in junior high school, and he started developing computer applications using basic programming in the MS-DOS environment. He has good experience in smart card programming as well as desktop and web application programming, such as designing, developing, and supporting live use applications for SIM Card Operating System Porting, personalization, PC/SC communication, and other smart card applications that require the use of C# and C/C++. He is currently a senior smart card software engineer at Cipta Srigati Lestari (www.cslgroup.co.id), an Indonesian company that specializes in the innovation and technology of smart cards. There, he holds the position of the smart card tools team leader. He has the responsibility of managing the smart card tools team and developing various applications and tools in order to create smart cards that can connect to any computer application. Before this, he worked as a platform engineer at the same company. In this position, he successfully ported the GSM operating system from Tongfang THC20F17BD Chip (MCS51) to Xirka XSTSCSIM864 Chip (MCS51) and the RUIM operating system from Samsung S3FC9xx Chip (ARM) to EMTG97 Chip (MCS51). He also successfully developed a personalization tool for the MIFARE Classic card, a smart card key generator dongle used to activate the operating system based on the ICCID number using its own cryptography algorithm, and various smart card applications. He did this by accessing smart card readers using P/Invoke C#, RESTful applications that use HttpNet and JSON XML serialization in C#, and responsive applications that use multithreading and asynchronous processing in C#. This is his first, and he plans to write as many books about C/C++ and C# programming in the future as possible. You can reach him through his e-mail at firstname.lastname@example.org.
