Lab projects(Internships) deals with cutting edge development work on practice-oriented problems. Invovles requirements engineering, design, implementation, & testing of scalable software components & protocols to solve the given problem.
I enjoy participating in Hackathons & coding challenges - innovative apps, cloud, micro services, analytics, mobile, NoSQL databases etc. They are agile, bring out hidden potential, learn to react quick, fail fast prototyping and of course very great learning.
Most of my courses have optional lab works to complement theory work. These work might involve software building and experimenting, getting familiar with implemenations and infrastructures, based on the theory content for respective course work
The project involves design and implementation of a Sensing system that opportunistically collects data. The challenge was to develop the engine that dynamically adapts this collection based on User and device context. The app collected location and context information that could be used for location services like Forums and community detection algorithms, and other emerging social business technologies. The Big data from huge user base was backed with IBM Bluemix mobile cloud services for Storage, Processing and push notifications (using Google Cloud Messaging)...view more

The idea is to help 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!!". The app runs on cloud infrastructure provided by IBM Bluemix and uses a NodeJS Server with scalable NoSQL Cloudant Database, Android app client for Geo-fencing and notifying server.
Technologies Used: IBM Bluemix Cloud, NodeJS Server, Cloudant NoSQL Database, Android Geofensing with foreground service, UI - Web & Mobile friendly AdminLTE Bootstrap, D3.js, Android Studio
The application "RefugeeBook" helps refugees to get in connect with companies. It uses data (user profiles, company profiles, job profiles, course profiles) stored in SAP HANA and matches these data in order to make smart recommendations. This is done by using text mining and machine learning. Additionally, it offers a meta-search to search for online courses on different learning platforms ("google for online courses"). Which helps the refugee to get certificates and gather new knowledge easily. This allows him to verify his knowledge to his potential employer.
