Software Developer, GoalWerks Inc., Sunnyvale, USA Apr 2011 - Present

It’s a stealth-mode startup developing a Social Productivity Platform that enables a fundamentally new approach to how individuals and teams interact with the computer. It is delivered as a next-generation web app from the cloud.

The client implements a UI that is intuitive, visually elegant, yet functionally sophisticated; will employ the AJAX design style; and will be implemented in Javascript/CSS3+/HTML5+. The server manages complex data models, performs heavy data mining, and will be implemented with highly-concurrent abstractions.

Technologies: HTML, JavaScript, AJAX, jQuery, CSS, Ruby
Web Developer, Intelligent Systems Division, USC/ISI, Los Angeles, USA Mar 2010 - Dec 2010

My Duties included developing a user interface to display results of genetic association studies (https://pagestudy.org) whose datasets were stored in a remote MySQL server using Google Web Toolkit (GWT) and Java.

Developed a GUI simulator to analyze effects of factors like temperature, currents etc on underwater acoustics.

File Transfer Utility (C++, Unix) Spring 2010
Developed an application that transfers a given file reliably, using UDP, between any two hosts.

IP Router (C++, Unix) Spring 2010
Developed a simple IP router in user space that routes packets from any source host to its designated destination host using libpcap library.

Operating System (C, C++, Unix) Fall 2009
This project involved the making of 4 major modules of any modern operating system: Thread management, Multi-programming, File systems, and networking for a very simple, but a functional, operating system called NACHOS.

Other Projects
Smart Code Analyzer and Tutor (HTML, JavaScript, CSS, GWT, JAVA) Fall 2008
A browser based programming tool, similar to an IDE, which would help improve a student’s programming skills to professional standards and analyze his programming style.

Web Based Chat Client (HTML, CSS, JavaScript, AJAX, PHP, JAVA and MySQL)
 Fall 2007

“Marina-scale Water Temperature Sensing in Real Time Using Microtomography ”, Devang Negandhi, Andrew Goodney, Kunal Joshi, Prof. Young Cho, Fourth International Workshop of Sensor Networks (SN 2011), June 20, 2011.

In the wake of the torpedo attacks and disappearance of North Korean shark-class submarine from the sonar as well as massive oil spills in Gulf of Mexico that is difficult to track, we recognize the mounting need for a high resolution, in-situ underwater monitoring technology. One of the well studied technologies for underwater temperature and current monitoring is Ocean Acoustic Tomography. The traditional use of the technology is to construct low resolution temperature and current map of large bodies of water for various studies in global changes in ecology and climate. We have taken the key concepts behind the technology and applied it to distributed underwater acoustic sensor network to enable marina scale underwater acoustic tomography. Since the area of interest is significantly smaller, we find that precision of time measurement and synchronization within the network has to be very high in order to produce meaning temperature map. On the other hand, the reduced scale introduces a new opportunity to utilize the technology to sense even the slightest temperature changes underwater with proportionally smaller delays. In this paper, we present our prototype wireless underwater acoustic sensor nodes and the experimental results that indicates temperature resolution below tenth of a degree Celsius. We also present our micro-tomography simulation system that is used to analyze the feasibility and the requirement for the wireless underwater acoustic sensor network for building marina scale underwater acoustic tomography.

“Frame Based Intelligent Tutoring System with Weighted Attributes and Adaptive Hypermedia”, Prof. N.Ch.S.N.Iyengar, Aditya Chopra, Devang Negandhi, Soumith Chintala, # The 2009 International Conference on e-Commerce, e-Administration, e-Society, and e-Education (e-CASE 2009), Singapore, January 8, 2009.

In this paper, we present an adaptive tutoring system for students of multiple domains with a web-based interface for flexibility. The displayed media is adapted according to the student’s capability and aptitude by evaluating the student according to historical data and quizzes. The media is divided into dynamic frames and content of each frame is displayed adaptively. A weighted approach is used to evaluate the student capability and frames are generated based on a beta distribution. Initial evaluation of the system based on a paper simulation showed encouraging results.
