EXPERIENCE
GTBIT, New Delhi - Hadoop Developer (Lead Developer)
Jan 2016 – May 2016
Project: Stock Analysis.
Description: This project was developed to generate a Fortune teller for stocks. This worked with the deployment of machine learning with Hadoop. Custom written algorithms were put into use to give the application a sense of how to determine the output. Multiple aspects like the stock value, market environment, tenders, past year data & historical data were taken into account.
Responsibilities:
●I worked with the historical data sets and also on getting new information of any tenders passed or deals placed. We started off with 5 companies, but gradually we increased.
●I had worked on to getting the data into the system. I was working on HDFS, Hive and Map-Reduce.
●Also, me and my mentors worked on making the algorithm that would support our project in a way that it had to be made just once, but can be deployed on multiple data sets.
●The Algorithm took around 70-80 days to be deployed while the data was successfully stored in Hbase.
●The result being that we were able to get nearby 68% success rate, which was higher than expected. The reason for only 68% success was because of the fact that the application was in its growing stage and therefore, would give higher accuracy as the data grows.
Stock IO Technologies, New Delhi - Hadoop Developer (Sub-team developer)
