PROFESSIONAL EXPERIENCE

Technical Lead /Hadoop developer

Confidential, New York

Responsibilities:

• 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 Leader

Confidential, New York

Responsibilities:

• 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

Component Leader

Responsibilities:

• As a Component lead responsible for Analysis, design, development, testing and implementation for the entire Confidential POWER system endpoints in the appliance. Confidential Smart Analytics System is an appliance that provides broad analytics capabilities on POWER systems warehouse foundation and storage. Deeply integrated and optimized, Confidential 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 Confidential 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 Confidential Cognos and Confidential SPSS.

Environment: Rational Application Developer, AIX, Python scripting for automation

Component Leader

Confidential

Responsibilities:

• This project show cases Cloud computing capabilities using Confidential POWER systems and storage. This was done in collaboration with Confidential 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.

Manager

Component Leader

Responsibilities:

• 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.
