Education • MS – Computer Science from California State University - Northridge. GPA – 3.51 (2003 – 2005) • BE – Computer Science and Engineering from Gogte Institute of Technology (1996 – 2000) Skills • C/C++, Python, Unix Systems Programming, Sockets/threads/Ipc, assembly, RS – 232 • OS – Linux, uClinux, Windows, VMware (running windows under Linux) • Tools – gdb, Strace, CVS, VMware, autoIT, Expect • Devices – Oscilloscope, FC – analyzers, Smartbits Traffic Generators Professional Experience: Organization: iQstor Networks Inc, Newbury Park CA. • Period: July 2006 – Present (2+ years). • Designation: Software Engineer. • Area of Business: Storage Area Networks, SATA and fiber channel communication, SCSI, Raid syst. • Work description: • Providing low-level driver level solutions to the iQ2280 SATA based storage controller, more specifically providing low-level bypass solution to the Silicon Store SS1200 SATA failover switch during system boot up to prevent cascading failure. • Improving IOp count and system through-put by improving shadow cache performance through the introduction of the ARC (Adaptive Cache Replacement) algorithm and improving system operations by re-design daemons. • Performing low level debugging and troubleshooting of tightly connected system code and introducing feature enhancements in both (iQ2880) fiber channel based and iQ2280 SATA based storage controllers. • Detecting week points and performing system tests such as clustering tests to detect flaws in various releases of the firmware. Also providing low level and high support to existing product lines. • Development environment: Linux, C Language for the Monolithic K9 kernel, Python. • Achievements: Providing solutions to complex problems relating key areas of system operations and product performance. Organization: Trango Broadband Wireless Inc, San Diego CA • Period: October 2005 – June 2006 ( 7 months) • Designation: Software Engineer • Area of Business: Fixed point 80211 based devices. • Work Description: • Performing automated system level and high level tests by creating test plans for various software releases for 80211 based wireless subscriber units and access points. • Writing control scripts in Python to control various testing devices, including the wireless products and smartbits and RF calibration units, thereby implementing an automated test program for various software releases. • Development environment: uClinux, C, Expect and Python. Organization: NXTV Inc, Woodland Hills CA • Period: March 2005 – Oct 2005 (7 months) • Designation: Software Engineer • Area of Business: Digital Media Entertainment • Work Description: • IPGAMES project which involved developing a low-latency video Capture Card based on multi-core blackfin DSP processors; dealing with MPEG-2 compression, low-level data transfers and caches. • Performing sustaining in order to increase set-top box product support for multiple vendors. • Improving Infra-Red receive logic using the inverted differential Manchester encoding scheme written in Atmel assembly. • Testing and improving the port of Linux to blackfin on the BF561-EZKIT. Pinpointing vendor specific software support issues. • Development Environment: VisualDSP++, GNU – Blackfin utilities, Linux, Atmel – assembly, cvs. • Achievements: Reaching advertised performance levels in Video Streaming. Daniel Measurements and Control (India) Pvt. Ltd. (India). (Emerson Process Management Group) • Period: April 2001 – Jan 2003 (-2 yrs). • Designation: Software Engineer • Area of Business: Real time Terminal Automation Solutions for Petro-chemicals units. • Work Desciption: • Developer in the design and implementation of software modules written for the Mark III Ultrasonic flow meter which included writing several key application daemons and APIs for an embedded platform running under Linux. A low level embedded database engine called mirdd (freeware), initially implemented as a shared library was modified to incorporate multi-threading and client-server approaches to overcome blocking on system call handling. The daemon was implemented in real time multi-threaded form which would work by user space mapping and locking itself in system RAM and using the /dev/mem interface. Power fail safe features and cache features were introduced to implement secure transaction sync and to reduce latency. • Developer in vendor specific custom development and enhancement of the Terminal Automation Software (Autoload 2 real time distributed data gathering application), handling post site installation issues and troubleshooting. Overseeing system deployments. • Development Environment: Linux, Pro * C, Oracle – 7 for Unix,shell. • Achievements: Successful delivery of each milestone in the MARKIII project.
