Contribution to Soot Repository
2016
Added a new feature to Soot. The insertOnEdge API adds instrumentation(s) to the Chain in a manner such that the resulting CFG of the program will contain the instrumented code (toInsert) on an edge that is defined by point_source and point_target. For more details, click here.

Null Dereference Analysis
2015
Given a Java program, this tool performs interprocedural pointer analysis on a user-specified method to verify a given dereference as safe or potentially unsafe.
YeNo
2015
Answering questions takes time. But there are many questions for which we’d require an answer in an instant for it to be relevant. To solve this problem, we made an app called YeNo. Developed as an OnePlus Hackathon project, this application lets users ask questions to any person at a particular location for which the answer can either be a yes or a no. Is there a queue at Starbucks? Is it raining in Electronic City Bangalore? Does McDonalds in Delhi serve veg burgers? This application lets one get answers to such questions (and lots more) in an instant from people who probably are aware of their surroundings. Answering questions just requires a person to click either yes or a no on their Android Wear device or the lock screen notification of their phone.
Disaster Management Using Crowdsourcing
2014
During a disaster, information is at a premium. There is an urgent need to know which areas are affected, how they are affected, what the priority problems are and so forth. The advent of modern connected devices, such as mobile phones, has provided a new digital development infrastructure, which may be of significant value to disaster response. When existing surveillance sensors used by a disaster warning and response system cannot provide adequate data for situation assessment purposes, crowd-sourcing information collection can be an effective solution. The goal of this project is to arm people with wireless devices that can be used as mobile human sensors. Eye-witness reports from them are used to complement data from in situ physical sensors and provide the system with more extensive and detailed sensor coverage.
Locate!
2013
This is a game for Android devices where the user has to pin-point locations, provided to them as text, on the map. The locations are stored on a java server created using Glassfish4. The closer they pin point the location the more points he gets.
Airplane! (Game)
2013
The goal of this game is to fly as far as possible, with only two controls at your disposal, this is one of those "easy to learn, difficult to master situations". You’ll first select a plane and a scene. Click once to start make your little guy take off from an airport, and it’s on!!
This game was made using OpenGL APIs.
Crack MD5 Password
2013
A tool to crack passwords that have been hashed with MD5 using brute force methods.
Automatic Ticketing System
2013
This is an android application which allows us to implement automatic ticketing to the user. All that a user would have to do is tap his NFC enabled phone against a NFC tag present at the entrance of various transport medium (like bus, rickshaw etc.). The GPS of the phone will be used to measure the distance traveled by him and will be accordingly charged from his online account. The need to carry cash (and change) and various other problems like corruption on part of rickshaw drivers and conductors can be eliminated.
Online Treasure Hunt
2013
A web application developed using PHP. It is used to emulate an online treasure hunt where people crawl through the web to find out the solution to the question provided.
