At my job I was assigned a really interesting project of moving the entire database from RDS to a No SQL structure. Used Amazon Dynamo DB for this purpose and learned the concepts of Keys, Indexes, GSIs, LSIs, Sharding and Overloading of Keys and many more. Got to know various use cases where a No Sql design can be much effiecint and scale well.

During my first internship at India Meteorological Department, I was assigned the project of building a web application which could fetch the details of an earthquake activity [long, lat, height, depth, magnitude] and could plot a heatmap over the map of India for a better visualization of the incident. I used Google Maps API to build the project along with a File Storage System.

Inspired by the course: 'How to build a Search Engine' which I did on udacity, I decided to build my own dummy search engine. I developed a web crawler in Python which could scrap all the links from a particular web page. I initially used it to scrap all the sites which provides courses online. One could enter the desired course Name and it will return the related courses. I also designed my ranking algorithm to rank result items in descending order of their relevance using string matching algorithms.

It was a semester end project which I developed on android. Developed an Android 8 Puzzle Game which can be played through Voice Commands. I also implemented a feature to control the difficulty of the game by varying the number of swaps made in the original sorted puzzle to produce a new solvable puzzle.
