Employment History

 

HCL America, Inc.            Hauppauge,
NY

 

2008 – 2011                Architect, eTrust Integrated Threat
Management Development


 
WindDbg
     debugger extensions.  Created
     WinDbg extensions to examine, perform sanity checks, data validation, and
     data integrity checks, and search for data corruption in the data
     structures in a Windows file system filter.  This satisfied three organizational needs – more timely
     diagnosis of problems through more effective post mortem analysis of
     dumps, more information about driver performance in the wild through use
     of this tool at customer sites, and better quality during the development
     process because it naturally facilitated regression testing.
 
Pathological
     Windows driver performance correction. 
     Diagnosed 3 separate errors in the internal data tracking
     components of a file system filter driver that when triggered
     simultaneously caused the driver to consume 100% of a CPU. The problem
     existed for years partly because the organization believed the code in
     this area to be foundational and time tested, partly because it didn’t
     cause system failure (rare customer dumps), and partly because it was
     intermittent and unpredictable (there was no understanding of the multiple
     conditions required to reproduce the problem). Corrected the functioning
     of the data tracking lists. Compared the driver performance using
     specially designed benchmarks and tests designed specifically to recreate
     the pathology.


 

CA, Inc                        Islandia, NY

 

2006 – 2008                Architect, eTrust Integrated Threat
Management Development


 
Re-architected
     interprocess communication in a Windows driver. The user mode scan engine
     was being replaced by a kernel mode scan engine. This required redesign of
     the interface between the Windows file system filter driver and the scan
     engine process.  Created benchmarks
     to compare the performance of the existing and new implementations.
 
Reduced
     Windows driver CPU utilization 10%. 
     Created an event driven thread management facility to optimize
     thread pool usage after analyzing Windows file system filter driver and
     thread pool performance characteristics. 
     Measured results through disciplined and comprehensive
     benchmarking.
 
Hooked
     Windows applications. Refactored the Windows user application hooking
     functionality of an anti-spyware product to improve reliability and
     performance.  Modified thread
     injection and address table handling routines.


2004 – 2006                Senior Manager, Unicenter Common
Services Development


 
Redesign
     an inter-process communication facility. Designed enhancements to a common
     communication component to add message persistence with delivery service
     level options and store and forward, message compression and encryption,
     and configurable message queue priority.
 
Development
     management.  Managed a team of
     three developers adding encryption and authentication to a multi-platform
     communication facility.
 
User
     mode deployment utility.  Created a
     Windows utility to search for and update a common component in product
     distributions

1997 – 1999                Developer, Unicenter Windows File
System Filter Driver Development


 
Diagnostic
     trace enhancement.  Modified the
     tracing facility of a Windows file system filter driver to improve the
     throughput of traces by a factor of three.
 
File
     system filter driver porting. 
     Ported a Windows file system filter driver from NT 4.0 to Windows
     2000.
 
File
     system filter driver development. 
     Added user mode accessible, per user process, memory and I/O
     resource utilization tracking to a Windows file system filter driver.

Services Development


 
Windows
     services.  Completed the Windows
     service implementation of a facility to manage the communication with, and
     control of, agents on a Windows system. 
     The facility was originally implemented on Unix and the development
     team stalled in their Windows implementation.  Redesigned parts of the implementation to conform to the
     Windows services model, improved the performance on Windows.
