* Led design and development of Client Operation Center (Silverlight) web
applications, encompassing database, business/workflow, and
presentation tiers.
* Developed vRadConnect (ASP.NET) a RIS web based system.
* Redesigned existing DAL components by emitting dynamic code at run
time. Resulting in 20x speed improvement when converting data
returned from DB to DTOs.
* Developed RIS web based application.

Silverlight, Telerik, WinForms,SQL

* Designed and developed Central Logging system for multiple production
services and clients, using very fast custom RPC algorithms.
* Designed and developed high performance and netCDF data collection
system for real time weather observations and forecasts used by Power,
Utility, and Transportation companies. Raw weather data from multiple
sources imported into netCDF format on Windows platform with retrieval
functionality on DEC and Linux platforms.
* Ported a lot of legacy C++ MFC code to .NET platform (C#).
* Designed and developed weather text decoder system, also wrote
AIRMET, SIGMET, TAF, METAR, SYNOP decoders to be used in automated
in weather displaying systems for AviationSentryOnline, and automated
weather alerts for Energy and Transportation business sector .
* Designed and developed many DotNetNuke ASP.NET modules for
Meteorology and internal IT operations.
* Designed and developed Quality Control System for incoming weather
observations.
* Designed and developed statistical analysis software for determining
"Normals" weather based on previous years of observed data.
* Designed and developed commodity trading analytical software
predicting crop production yields based on season's moisture levels
compared to previous years' data.
* Re-Designed and developed new MADIS ingest system (netCDF to
MSSQL). Legacy system had too many performance limitations allowing
only a small subset of station data provided by MADIS. New system can
handle the entire data set at a fraction of the cost (speed).
* Designed and developed many RWIS related components in TSQL, Java,
and C# to accommodate data feeds from common systems such as
Clarus System and from dedicated DOT feeds.
* Tools: x86 MASM, COM/DCOM/COM+, C#, .NET, Visual C++, ATL, MFC,
STL, GCC, SQL, Java, netCDF, GRIB, GRIB2, ESRI Shapefile.

* Analysis and optimization of C++ code to resolve performance
bottlenecks in processing giga/terra-bytes of data, used in Retek's
predictive framework applications, running on Sun and AIX machines.
* Tech: GCC, GPROF, Cygwin

* Developed COM-bridge with legacy DDE enabled application for
Pacemaker telemetry board interface communications.
* Developed custom data streaming interface between Linux and
Windows platforms based on custom Remote Procedure Call engine,
transparent to the physical connection: Serial or IP interface.
* Developed system to execute Linux shell commands remotely from
Windows client.
* Developed system that extracts plain text from Adobe PostScript files,
for capturing and evaluating printer output.
* Developed template library to gracefully handle COM errors for both




client and server side.
* Tech: C#, .NET, Visual C++, ATL, STL, MFC, Sockets, PRC,COM/DCOM,
Java/J2SE, GCC, G++,Ghostscript

* Designed and developed framework of WDM Windows drivers (SCSI
miniport, and kernel mode drivers) for mounting multi-format captured
disk images to the Windows OS as another physical disk in the system
for electronic forensic industry. This allowed users to work with the disk
drive as if it was directly connected to the system, rather than a
collection of files and directories representing physical sectors of a
drive.
* Tech: NT DDK, DriverWorks, SoftIce, WDM, VxD, SCSI miniport, C++,
ATL, MFC, x86, Masm

* Developed Windows kernel mode driver for custom high speed data I/O
board, capable of transferring 200+Mb of data in less than 8 sec.
Programmed AMCC (matchmaker) and Altera Flex 10K ICs. Used in a
new generation laser printer for MRI / CAT scans.
* Developed numerous COM solutions for upper layers in health imaging
printer modality to manage image transfers utilizing IO Completion
Ports, Multithreading, and other performance optimization methods.
* Lead on technology decisions, development style, and dead-end
technical issues. Technology and methodology mentoring junior level
engineers on OOD, COM, Win32 internals, and many other issues.
* Influenced team and ported legacy code to Component based Windows
2000 modules. Improved error handling and error logging techniques
for new software components.
