• I built a product attribute extraction engine using biltsms to resolve stock keeping units and enrich the reference entity graph to reflect dynamically changing markets.
• I also developed an approach for removing the ambiguity and establishing the confidence in the resolution/mapping of customer stock keeping units to our catalogue.

• Customized Constraint Based Indoor Path Planning for Handicap Users on Smartphones:-
• Purpose -Adapting grid path planning according to various constraints such as user constraints (size constraints for wheelchair bound users, structural support constraints of visually handicap and instruction constraints.) and localization constraints.
• Features:- Localization using WIFI and GSM Signal Strength Mapping along with available onboard sensors like accelerometer, magnetometer and Gyroscope gives the user’s exact location on the map. Path Planning is done with implementing Dstar algorithm. Various constraint problems are addressed by modifying cost matrices dynamically according to user handicap and optimizing them using linear programming. For example for visually handicap no. of breaks in the structure beside the path, unused doors on the way, hand preference and orientation are also accounted for. The cost matrix for the map is initialized with a cost proportional to the distance to closest wall as they tend to walk along a structure(wall, fence etc)

• RUSH DEFENSE – an ios application for a tower defense game for ipad
• All the bullet collisions and player enemy collisions were handled using chipmunk physics engine with cocos 2D . It has shades of a traditional tower defense game, as the user has to protect a HOMEBASE, from various waves of different kinds of ENEMY ALIENS originating from different spawn points. Every character (enemy/troop) on colliding with any other character/ defense buildings dies instantly. Any bullet collision reduces the target’s hit -points. There are nine defense buildings broadly divided into 3 categories STRUCTURAL, SUPPORT, TROOP . they have different upgrades There is another HUD layer on the to display all the gameplay information .

• Android-Based Library Way Finding Application : -
• This application provides the mobile user with the location, shortest path and the directions to follow that path .The app is modeled and implemented on the institute library of Dalian Maritime University. It takes the name of the of the book and the author as the user input, finds the book’s location from the database and gives the desired output on the map.
