Responsibilities:

• Development and enhancement of RESTful java-based services that would actively help in syndication and

loading of legal content efficiently and reliably from various publishing resources to the backend XML-based

NoSQL database called MarkLogic.

• Processing and parsing large number of xml documents using java xml apis like SAX and DOM parsers,

stylesheet processing on large sized xml documents using Saxon XSLT processor and also XQUERY/XPATH

for querying in MarkLogic

• Smart implementation and management of thread-pools for multithread processing of the large volume of

data to achieve maximum throughput using java concurrent package and design patterns like Factory/Single-

ton/Composition

• Developed a dynamic configuration dashboard in MarkLogic to dynamically control throttle levels of the

Restful java services like thread allocation and deallocation, pipeline queue thresholds

• Creating batch processes using UNIX Shell Scripts to processes millions of xml documents and automate mail

notifications using cron jobs to alerts users

• Migration strategy planning and development to migrate from a filesystem based point-to-point ingestion

methodology to a Publisher-Subscriber based model

• Enhanced the efficiency and reliability of the system by introducing a workflow based model by creating a

workflow and data-map syndication database in MarkLogic

• Achieved throughputs of up to 1 million documents per hour by efficient use of thread pool and memory

management as well as performance engineering tools.

• Research and Design, Data Querying and Pattern Analysis, Performance Research and Engineering, Software

Development and Testing

• Streamline overall processes of application development for major releases using Agile Methodologies.

• Managing and coordinating development of projects using onsite and offshore development procedure

• Code refactoring, Implementing JUnit Test cases, developing various tools like Publisher Tool, Data Inventory

Tool, Document Load Status Reports, Syndication Report Application Tool, HUB Synch Tool

!

reports. Feed Validation systems validated the various feeds generated on a daily basis.

Responsibilities and Achievements:

• Migration of the legacy Search Marketing Log Collection and Reporting system to a Java powered platform

responsible for pulling feeds from JMS pipeline queue and push to the Oracle database. This involved han-

dling large amount of data generated from the search monitoring applications.

• Design and development of standalone java application client for pulling and validating log feeds from the

JMS pipeline queue using point-to-point messaging

• Processing and extracting required information from the message and executing SQL statements and Stored

Procedures using JDBC to update Oracle DB

• Added new functionalities to the Search Marketing and Reporting web application to make reports available

in various formats like graphs, excel, tables by using open-source libraries like JasperReports

• Onsite coordination, planning and managing day-to-day activities and interaction with the client to facilitate

smooth implementation.

• Analysis and interpretation of lapses in the application or database to identify key areas affecting the perfor-

mance of specific features.
