  • We built a tool to automatically convert current Natural Language to Java Language.
  • Code cleaning post Conversion to Java language.
  • Data Validation - Comparing legacy data against Data rules and investigate the invalid data.
  • Core work requires analyzing code, identifying defects and making changes to ensure code is fully functional and adheres to the given requirements.
  • Used Agile methodology in designing and developing the modules.
  • · Developed MVC design pattern based User Interface using JSP, XML, HTML and Struts.
  • Participated in and contributed to group sessions, design reviews, and code analyzing.
  • Daily Scrum meeting , weekly timelines for ensuring Project Delivery within given timeframe
  • Used Java Beans for communication from UI to the backend server.

  • Implemented a generic way of parsing messages using Java Generics and that ensured the parser is picked up at runtime depending on the message type. Message Type is derived using Xpath based look up. Used Factory Design Pattern for selecting the appropriate parser for each message.
  • Designed a generic table structure for storing multiple message formats in DB2.
  • Query in memory Oracle Coherence which was distributed across nodes to cache configuration and product related information.
  • Ensured that transaction is maintained while processing the message and none of the message gets lost using Spring Transaction Manager.
  • nvolved in writing code to transform XML documents using JAXP (SAX and DOM Parsers) and XSLT.
  • Used Spring along with the Spring Integration Framework to do the message flow in the component. This enables lot of parallel processing with in the component.
  • The batching of the results of the messages while persisting to DB2 was important, so we used Spring JDBC template for persisting the results.
  • sed Agile methodology in designing and developing the modules.
  • Worked on High Volume Transaction Processing environment to process more than 10 billion messages per day.
  • Ensured the scalability of the component, to cater to a high volume and yet maintain the order of processing. This involved lot of Multithreading for each of the functionality.
  • Used Messaging queues (JMS) for point to point communication.
  • Wrote a JMS message listener with a retry logic for retrieving messages from IBM MQ Series. Whenever an exception occurs, the components retry the messages 3 times before sending it to the error or discarding it depending on the configurations.
  • Made synchronous/asynchronous TCP request to another component to get the portfolio related information needed for processing the message.
  • Developed Trade based User Interface using JSP, XML, HTML5 and Backbone.js.
  • For Form validation, and better user interaction on the UI, we have used Javascript Jquery library.
  • mplemented upload functionality in UI, so that trades can be uploaded in CSV format in an excel. Used Jquery for validating and posting this to the server.
  • Used CSS3 to display the trade information as a grid in the UI.
  • Used Sass as a CSS Preprocessor.
  • Used Struts validator framework to validate user input.
  • Created WSDL for the web services to be deployed using bottom-up approach.
  • The Authentication was important part of the Web Service, within the firm we mostly used user Id based Kerberos token authentication.

Role: Java Developer.


  • Design DB2 tables , which are used for easy addition and Configuration for a recon
  • Using Spring JDBC Template Write Data Fetch from DB (for query as well as procedure) and from file using buffer readers. Since Read is Faster than write, we implemented Producer-Consumer pattern, with read thread being Producer, writer thread being consumer. By having more writer threads, we archived Multithreading in the component.
  • Batched the Results before Persisting the Data fetched into a table.
  • Write the procedure for various Databases like MYSQL, Sybase, DB2 to fetch the data from table as needed by the recon.
  • Used Spring to do the database Connections, Transaction Management and for sending and receiving byte messages Over MQ.
  • Developed UI for viewing the recon results (MATCH, MIS-MATCH) using HTML5 and CSS3.
  • Developed MVC design pattern based User Interface to view the Recon data using JSP, XML, XSLT, HTML and Struts.
  • Involved in Writing components to export the Recon Results to an Excel on the UI,
  • Used JSF framework in developing user interfaces using JSF UI components for setting up new recons.
  • Developed JavaScript functions for front end validations. The frontend would request backend for data and server would return the data in JSON format using JQuery Library.
  • Front end would display the results, with various counts (same, missing, or duplicate) .
  • UI has the ability to fetch the recon data for a given date at a client level. The Client List is auto-populated on the UI using AJAX request, made to the server using Jquery .
