Local Siri is an Android Application that opportunistically senses and uploads users Location data adapting to the user's Context such as battery level and connectivity. This App helps users with their queries by providing a Location based chat Forum. Data collection and upload is implemented as a background service. It includes a monitoring feature to visualize this. It involves Efficient Processing of Location Data and Intelligent User Aggregation based on the Context.

IBM BlueMix (PaaS) cloud platform is used for developing the Server Side components, for supporting large User Scalability, Grouping Location based information, pushing Notifications to relevant Users. Querying the huge location data is done by map-reduce paradigm supported by the Mobile Data Cloudant (DBaaS) that uses CouchDB as the backend database. Push Service helps to notify users through the configured Google Cloud Messaging API.

Technologies: Android, Java, Node.js scripting, IBM Bluemix Cloud Services (Mobile Data and Push), HoloGramChart, Git, Google Cloud Messaging, Intellij Android Studio, IBM Jazzhub, JSON

WiFriends is a Social Networking Android Application that automatically exchanges User profile via device-to-device communication. It uses Wi-Fi Direct Network Service Discovery to discover friends and share profile information among friends.

Secure Data transmission is accomplished by encrypting the user profile and images using AES 256 bit encryption. The AES key is exchanged securely via Near Field Communication(NFC) during the add friend stage. Material Design UI (Android Lollipop) is also incorporated into the application.

Technologies: Android, Java, SQLite, Cryptography: AES 256 Encryption, WifiP2P API, Spongy Castle API, Git, Android SDK, Material Design UI for Android Lollipop, JSON, GSON API

The app helps users(students and university members) to figure out "How occupied a particular building(say, Library/Cafeteria) is?". It provides a Web and Mobile application to display current seat availability vs capacity, with attractive and dynamic charts. While doing so, it also provides a twitter chat room for each location, facilitating users to discuss events happening at that location, like "Hey, good food at the Cafeteria today!! Don't miss!!".

Technologies Used: IBM Bluemix Cloud, NodeJS Server, Cloudant NoSQL Database, Android Geofensing with foreground service, UI - Web & Mobile friendly AdminLTE Bootstrap, D3js.

Business innovation and IT SAP mobile app competition took place at SAP headquarters in Walldorf which aimed at creating an app that fosters productivity in the workplace at SAP. We learned about SAP software, collaborated and co-innovated with fellow enthusiasts from SAP, developed prototypes of solutions to complex real business cases and themes, and presented to an expert jury.

The app is named SAP On-Time and aims at scheduling/rescheduling/cancelling meetings and informing colleagues about late arrivals (Email notifications/Telephone calls). Meeting updates can be sent and it helps in users to be more punctual through gamification.

Tools and Technologies: 32 hours of hands-on experience with Technologies such as: Fiori UX, SAP UI5, SAP HANA Cloud Platform, JSON, XML, HTML5, CSS3, JavaScript, MVC Architecture and Innovative Design Thinking methodology with on-site domain experts from SAP.
