PROFESSIONAL EXPERIENCE

Confidential

SW Engineer

Responsibilities:

• The embedded controller is a part of the Surveillance Radar, and is a PPC, LynxOS based VME sized Controller that generates commands to operate the Optical Cameras.
• The software provides various commands to operate wide angled cameras such as Far/Near Focus, Pan/Tilt, Wide / Tele Control and host of other control and configuration commands.
• These commands are sent over UDP / RS422 interfaces between Optical Radar and the controller.
• The optical camera is a Cohu HD8800 based, 1080p, H264 type camera.
• LynxOS based tools are used for developing the software.

Tools used: Windows based LynxOS tools, C/C++, PPC (MVME550) based VME Boards in a VME Chassis.

Confidential, Hopkinton, MA

Sr Software Engineer

Responsibilities:

• Developer of software for Linux based Embedded Diagnostic Application.
• Added set of Test Commands that configure the operation of memory, disk drives, SSDs and peripherals, Sensor, Status LEDs attached to Storage Processors.
• These commands help configure, change or control different peripheral devices using serial, network, SPI / IPMI /I2C interfaces. Each of these commands implemented as synchronized multi thread cooperating processes.
• The Diagnostic application is part of automated testing framework used during manufacturing testing.
• Storage Processors are based on X86 family processors.

Tools used: C/C++ with Linux based tools g++, gdb, Eclipse, valgrind, Git version control, BMC with IPMI v2

Confidential, Bedford, MA

Sr Software Engineer

Responsibilities:

• Sustaining and Development for Session Border Controller Chassis.
• My role is to enhance network application functionality from vxworks 6.4 to 6.8, to analyze race conditions between competing tasks and fixing synchronization issues between them, to fix bugs, memory leaks and provide enhancements.
• The application is written as cooperative multi threaded tasks with synchronization constructs from the vxWorks.

Tools used: VxWorks / WorkBench, Tools to collect events, execution trace, shell scripts to load/unload dynamically object modules, Wind River's Workbench with GNU/Diab Tools for X86, Clearcase, UCM with ClearQuest, Packet generation with SmartBits, packet trace collection with WireShark, Valgrind, Coverity tool.

Confidential, Wilton, CT

Software Engineer

Responsibilities:

• Confidential is lithography platform that is used in semiconductor industry to process silicon wafers.
• My role, as a software developer, is to develop or modify software to incorporate new features or enhance existing features.
• The equipment, among other subsystems, has a robot that carries “reticles” between various entities.
• I have added enhanced diagnostic and event generating features to the reticle-carrying robot's movements and to classify the events into meaningful warning messages.
• The software also displays these events and warnings on Sun-based gui screens.

Tools used: Clearcase, ClearQuest, GCC compiler for Sun / Solaris 8/10, gcc compiler tools for VxWorks/Tornado, gdb/ddd and other in-house tools.
