This is a product and a plugin. www.e-txt.com .Explored new technologies, demonstrated the proof of concept.

• Tested, maintained and then developed web based applications using Microsoft technologies. (www.schoolnet.com)

• Played various roles for development of internal web applications using C#, Ajax, ASP.NET, and SQL server.

Project Trainee: Dexcel Electronics Designs, Bangalore, India ( www.dexceldesigns.com ) January 2006 - April 2006

• Code Optimization-Profiled (Pipeline) and coded instruction sets in assembly from C.(migration) Rewrite the intensive modules of ADSP-Blackfin 533 assembly for an image compression standard JPEG2000.

• Benchmarked the results and helped forming a white paper.

Implant Trainee- HTL LTD, Chennai,India ( www.htlchennai.com ) - Sophomore Winter 2003

COMPLETED PROJECTS

“Game Development -Beat the Dealer Simulator - VC++” May 2011

• A card game code in OOPS designed to have several instance of players to play with a dealer

• Examined, employed exclusive random number generators and developed a console application.

“Earliest Option between Air Terminals – C# .NET” January 2011

• An earliest option for a given schedule for any source to destination using in-memory data structures

• Employed Dictionary and data structures such as Graphs, Dijkstra algorithm, Stack to store, process, retrieve airline information and calculate between nodes (airports) using C#.net.

“Digital Filter Designs Using MATLAB” May 2010

• Designed IIR and FIR filters by scaling the register overflows and also analyzed quantization effects with varied bit resolutions for direct form structures in fixed point arithmetic.

• Designed filters for wave digital filters, also performed transformation using impulse invariance and bilinear transformation.

Scope: Filtering effects in Delta Sigma Modulators.

“Implementation of Pattern Recognition Algorithms on Raw Images Using C & C# .NET” May 2009

• Programmed managed codes to separate images into blocks of desired size after zero padding and then applied recursive 2D FFT of each image blocks and then made a phase plot and magnitude plot of any images (color /BW/ grayscale) to see the effect of the patterns. OOPS being followed methods could serve as dynamic link libraries.

• Formulated a histogram technique to see the effect of color components in images.

Scope: Design multithreaded UI for visualizing signal processing tools in C# with core programs in C/C++.

“Bluetooth Communication for Hand Held Devices Using C&C#.NET Micro framework” December 2008

• A simple executable in managed code (C#) to design Bluetooth application. The Bluetooth connection was established between a Windows OS and Windows mobile OS using its SDK (V 6.0).

“Code Optimization of JPEG2000 in ADSP Blackfin533 Using C& DSP assembly” June 2006

• Ported the assembly code of JPEG2000 encoder into ADSP-BF533 core development kit using visual DSP++ 4.5 developed for windows platform.

• Used all optimization techniques and restructured the assembly codes in terms of execution time, power consumption and memory management- Dexcel Electronics Designs, Bangalore.

Scope: Implement compression algorithms for multi-core DSP’s or into a custom -designed cores.

“Called External dll’s Using LabVIEW for Communicating Win XP with the Frame Grabber” June 2005

• Explored the dynamic link libraries under the guidance of Dr.Abhijit P Deshpande, Associate professor, Chemical Engineering, Indian Institute of Technology, Madras.

• Formulate a GUI program in lab view 7.1 to communicate with the frame grabber card using a dll.
