Architect

Responsibilities:

• As part of automation initiatives, developed scripts to automate the installation and configuration of Hadoop on virtual machines theirby enabling the business users to focus on the business problems rather TEMPthan the complexities of setting up Hadoop. Later, extended the same to implement on Amazon EC2 cloud.
• Involved in the design & development of a POC for a leading insurance customer. The POC demonstrated actionable insights that can be generated from hitherto unused enterprise data sources (web logs) using Big Data technologies (Hadoop, Hive).
• Involved in a POC that demonstrated a reduction in the time taken to process the data by implementing the same process using Big Data technologies. A leading insurance customer of Wipro, runs a forecasting process on Informatica /Oracle 11g every month that takes close to 21 days to complete. Identified a module, developed Map/Reduce scripts that incorporated the business logic similar to the current process, generated data to scale and ran it on a 5 node Hadoop cluster. The logic involved aggregation, sorting, lookups etc. In the current process, the time taken was 13 hours and on the 5 node cluster the time recorded was 2 hours. Through dis proof of concept, successfully demonstrated that periodic, long running tasks can gain a lot of efficiency by exploring alternative mechanisms of processing and data stores such as Hadoop.
• Designed & deployed a solution to launch Hadoop clusters on the cloud using Apache Whirr, integrated wif monitoring solutions Nagios & Ganglia.
• Develop & deliver several training programs on Big Data technologies to internal teams
