EXPERIENCE

Analytics using Hadoop for smart meter data

04/2012 - 11/2014

Technical Lead /Hadoop developer

IBM's Client: National Grid, Location : New York

National Grid is an electricity and gas utility company catering to

Northeast regions in US. As part of the smart grid strategy, National grid

rolled out smart meters to some of its customers. Smart meters relay a lot

of meter data back to the hub from individual customer location. This data

could be used for various purposes like dynamic pricing, quicker outage

notification and informed customer decisions, etc. Hadoop and other big

data tools were reviewed for this purpose.

Data from smart meters was loaded into HDFS using SQOOP. Map reduce

programs used this data to determine different meter data numbers that

could be used for calculations involving power usage. The processed results

were consumed by HIVE, Scheduling applications and various other BI reports

through data warehousing multi-dimensional models.

Import and export of data using Sqoop from or to HDFS and Relational DB

systems

Developed JAVA mapreduce programs for custom processing

Created Hive tables and wrote Hive queries using Hive QL

Developed work flows to schedule various Hadoop programs using Oozie.

Used Pig (PigLatin) scripts for ad-hoc data retrieval

Environment: Hadoop, SQOOP, Hive, Pig, Oozie, Oracle

Team Size: 5

Work management Solutions - Ischeduler & Common Work Queue

05/2011 - 01/2013

Team Leader

IBM's Client: National Grid, Location : New York

Worked on scheduling software using Java/J2EE, Oracle on UNIX and Windows

environment. These are used on an enterprise level for managing Electric

and Gas leak work orders which are dispatched to the field crews in real-

time and completion information passed back to the originating systems.

This enterprise solution involves handling huge volumes of customer work

orders, interfacing with different corporate and mobile units using

multiple Middleware technologies.

Implementation involved java, scripts in the ASA framework(proprietary),

Toplink and MQ for communication between components.

Environment: Java/J2EE, Oracle, Weblogic and iPlanet application servers,

Middleware technologies

IBM Smart Analytics Systems (ISAS)

08/2009 - 04/2011

Component Leader

Location: IBM India

As a Component lead responsible for Analysis, design, development, testing

and implementation for the entire IBM POWER system endpoints in the

appliance. IBM Smart Analytics System is an appliance that provides broad

analytics capabilities on POWER systems warehouse foundation and storage.

Deeply integrated and optimized, IBM Smart Analytics System provides a

single point of support for end-to-end analytics solutions on an enterprise

scale. These systems and the analytic applications are managed by IBM

Systems Director. I designed and developed the interfaces for the POWER

system endpoints in ISAS. Endpoints included AIX OS, HMC, and the actual

physical server within the appliance. The ISAS system will be used by

customers to develop analytic applications using IBM Cognos and IBM SPSS.

Environment: Rational Application Developer, AIX, Python scripting for

automation

Blue Cloud On Power Systems 10/2008

- 07/2009

Component Leader

Location: IBM India

This project show cases Cloud computing capabilities using IBM POWER

systems and storage. This was done in collaboration with IBM research. It

involved automated provisioning, resource allocation, de-allocation of pre-

canned images which include the AIX operating system with other software

like DB2, Websphere. I was involved with the development of interfaces that

interact with HMC, NIM, and VIOS. These scripts were used by Tivoli

Provisioning Manager Workflows to start provisioning and de-provisioning.

Environment: Perl scripting, Cloud type infrastructure on POWER system,

AIX, Rational Team concert, J2EE

Webservices Enablement Of Standalone (WPAR) Manager

02/2008 - 09/2008

Component Leader

Location: IBM India

WPAR Manager is a tool to allow an administrator to create, clone, and

remove WPAR (workload partitions within a Logical partition) definitions,

or start and stop from an easy to use management interface. It also has

check-point/restart enablement needed to relocate a WPAR from one system to

another using Live Application Mobility. There are a set of api's that

would accomplish the core functionalities mentioned above. My work involved

exposing these services as REST services.

Environment: OSGi, Java, JAX-RS(REST), Rational Application Developer, AIX,

Eclipse Programming, Rational Software Architect.
