Confidential, Morgan Hill, CA

Sr.Development Engineer

Responsibilities:

• Actively participated in architecture, design and development of Graphon thin client Desktop Remoting GUI application. This allows users to be able to access all flavors of UNIX platforms and Windows Servers. This involved capturing the windows API calls on the client machine, cache them, and compress them using the Graphon thin client protocol and send over the network with winsock (TCP/IP) calls.
• Tools and languages used are C++, STL, Win32 API, and Visual Studio.
• Initially developed a different prototype prior to developing the above product. This was based on the idea that a display driver that acts as a filter between the real display driver on a machine and the windows GDI. Any Graphics related call made by any application goes through the GDI, which in turn calls the display driver. And hence this driver can capture the display/graphics related activity and send it across the network using winsock (TCP/IP, WinDbg, and DDK. Visual Studio).

Confidential, Santa Clara, CA

Software Engineer

Responsibilities:

• Designed and developed GUI for Confidential system. This allows the users to make a VCD2.0 standard CD with Video clips from tapes, still images from photo album.

Device command set using ASPI( Advanced SCSI programming interface).
• Architected, designed and developed Windows NT kernel mode device driver for MPEG hardware. This encodes the real time video/audio into mpeg1/mpeg2 half D1. This involved downloading the micro code into the compression chips, usage of irq, fifo, programmed I/O and asynchronous calling to correctly handle the real time data flow.
• Also developed kernel mode library to partly implement ISA Plug and Play protocol to read the Resources assigned to the mpeg hardware above mentioned. This actually relies on the plug and play Bios for the conflict free assignment of resources.
• Developed an installable driver for YamahaCDR100 & Philips522 CD-Recorder and integrated it into Confidential encoding system. This involved correctly sequencing and timing between the device commands and asynchronous communication and multithreading in order to cater for various CD recording speeds (Win32, Visual IDE, and ASPI).
