Real Time Distributed System Laboratory, August 2001 - December 2002
Computer Science Department, Texas A&M University
Role: Software Developer
• Designed and developed a secure data transfer project based on Microsoft CAPICOM. The security involved Public Key Infrastructure, Encryption 3DES Algorithm and User Authentication. The purpose of the project was to create a series of methods to ensure secure data transfer between two peers using 3 methods above in .Net Technology. It was developed using VB.Net and C# and Winforms in .Net Technology.
• Designed and developed C++ .Net image manipulation tools where user could browse images in his folders and do pattern-matching based on the filters applied. Some of the filters involved were written in C++ and others in Matlab.
• Designed and developed medical patient-oriented image annotation, zooming, marking tools. These different medical tools were automatically associated with patient records database and were used as a communication channel between doctors through medical images (X-Rays) without damaging the image files. Technologies involved were C++.Net, C#, Winforms, ADO.Net and Microsoft Access.
• Designed and developed medical database applications showing patient records and integrated EKG and QRS databases. The EKG and QRS measurement devices could then be plugged into a handheld PDA and be used to measure heart rates and to measure the healthiness of the breathing system. Datas were processed using Embedded Visual Basic and stored through ADOCE connection into Pocket Access.
• Designed and implemented data signals manipulation and transfer using Microsoft MMLite Board. The board allowed signal transfer between multiple types of sensors and results were sent as bits through SOAP Protocol and displayed online.

Sperry-Sun Drilling Services, January – August 2000 & January - May 2001
Division of Halliburton Energy Services
Role: Computer Engineering Co-op
• Designed and developed a rig tester application, accessible both locally and in the net as an applet. The application stores the streams of data received and calculates needed environment attributes for the specific rig. The technology involved was Java 2 (includes Swing), JDBC and Oracle.
• Designed and developed a signal generator to simulate real-time signals coming from the oil rigsite. This generator should imitate both the low frequency and high frequency signals received from the rig tools located far below the earth surface. Each of the different signals received meant different attributes of the land and the oil. Technology involved was C++.
• Designed and developed the fast-forward and rewind feature of the signals stored in files. These files were stored from the real-time signals received from the rig sites. The buffer, the pipe, the timing and the scales adjustments were all done in C++ (includes MFC).
• Developed the GUI, the buffer and the pipe of the lowest frequency real-time signal received from multiple rig sites. Each of the tools below the rigs sent up to 16 signals at a time. The program buffered these bits, ran them through a filter, a pipe and displayed them as different real-time moving graphs. The application was developed in C++ (includes MFC) and C.
• Developed zooming and marking features of the signals displayed. The image rendering, the precise timing and the buffer are all developed in C++ (includes MFC).
• Designed and developed an interface layer between MATLAB and our huge signal database through C++ and ODBC. This layer provided flexibility for signal manipulation to be done in MATLAB through MEX functions. MEX is supported by Matlab to communicate data between MATLAB and C/C++. Besides the layer, I also designed programs in Matlab to execute C++ functions communicating with the database. This program retrieved signals, searches signal patterns, manipulates the signal arrays and then wrote them back to the database.
