Sr. Software Engineer

Responsibilities:

• Participated in design and development of this Java application used for bulk processing of xml documents representing groups/companies participating in Horizon small market segment health insurance plans. The processed groups would be ultimately stored in a transactional database for
• Confidential Group Configurator signature web application. This multi - threaded Java application would process batches of xml documents based on the information retrieved from a database table that the client would use to push batch processing requests. The application would then process each batch (dividing work among multiple threads) by updating database with transactional information retrieved from xml documents within a batch. This application was based on the Spring 2.6 framework, and used xstream parser to serialize/deserialize xml group documents. DB2 9.4 database was used for persistence. Hibernate 3.2 was used for object-relational mapping. Maven 2.X was used for building the application. Subversion was used as a source configuration management tool.

• Developed and maintained this Java application used for bulk configuration and load of Horizon’s large market segment health and prescription insurance plans in a transactional database for
• Confidential Plan Configurator signature web application. This multi-threaded Java application used plan templates, custom configuration rules and embedded product machine’s services and definitions to configure and load health plans in a database. The embedded product machine’s services and definitions were used first to load and initialize health plans. Then custom health rules and plan templates were applied to further configure health plans. This application was based on the Spring 2.6 framework. DB2 9.4 database was used for persistence. Hibernate 3.2 was used for object-relational mapping. Maven 2.X was used for building the application. Subversion was used as a source configuration management tool.

Software Engineer

Responsibilities:

• Web Service Developer for Institutional Alerts Management Project
• Participated in this large project as a TIBCO ActiveMatrix Service Grid web service developer.
• Developed a TIBCO ActiveMatrix web service to process and deliver Institutional alerts such as expired market orders, security transfers, order fills, option exercise requests, etc. for financial advisors. Among developed artifacts were TIBCO ActiveMatrix SOAP Service, TIBCO ActiveMatrix Java Component, Client Notification Service composite and a container of domain objects. The service processed high-volumes of Institutional alerts in a concurrent, disparate environment. The service processed both real- Confidential and recurring alerts. Real- Confidential alerts were generated by TIBCO BusinessWorks clients subscribed to a message-oriented middleware system. Recurring alerts were generated by the clients scheduled by SysAdmiral scheduling system.

Confidential

Consultant

Responsibilities:

• Worked on this web-based J2EE search engine application for an XML database containing information on more than 100,000 medical articles containing rich multimedia that was handled via Akamai infrastructure.
• Designed and developed this application end-to-end including both the search engine and the XML database solution. The presentation layer comprised a request-driven action Spring Web @MVC servlet framework v.2.5 with JSP, JSTL, XSLT 2.0, Excel view technologies managed by web container on Tomcat v.6.X servlet engine and accessed via Apache web server v.2.0. The middle-tier comprised Spring v.2.5 managed business objects providing a number of services such as browsing, searching, exporting to Excel, visualizing differences between multiple versions of the database. The data layer comprised Oracle Berkeley DB XML database v.2.4 that provided XQuery interface for document access.
• The business layer interfaced with the data layer via DAO that used XQuery-based access to documents provided by Oracle XML Berkeley DB database v.2.4. The back-end solution was to set up XML database to enable searching and aggregation capabilities since previously all that information was stored in the file system (more than 100,000 XML documents stored hierarchically) and it was not possible because of that to do effective and efficient information search and aggregation, and ultimately it was hard to manage it since the client was periodically getting additional versions of the articles. Developed a process for automatic build and update of new versions of medical articles using ANT, Java and XSLT 2.0 technologies.

Sr. Software Engineer

Responsibilities:

• Worked on design and development of C/C++ library providing fast and efficient retrieval of live and historical quotes on swaps, foreign currency exchanges, treasuries, Eurodollar futures, and other financial instruments for traders in New York and London. Live quotes retrieved through Reuters and the historical quotes retrieved through the firm’s proprietary Sybase/Oracle database.
• Worked on design and development of multi-threaded Java/.Net solution providing fast and efficient access to fixed income market data curves available through a network of distributed applications, analytics, interconnected via TIBCO/RV infrastructure. The first part of the solution involved design and development of a multi-threaded JMS client which would access that distributed infrastructure of the fixed market data providers through JMS interface using TIBCO EMS MoM as a JMS provider. The second part of the solution involved integrating .NET applications developed in C#, VB.NET to use this JMS client using .NET-to-Java bridge. Using the simple interface provided by the JMS client shielded from the complexity of asynchronous data processing, .NET applications would be able to request and receive large amounts of data from the analytics providers.
• Worked on design and development of a Java rule-based document library to provide effective conversions of derivatives documents in XML format. This powerful thread-safe library used XSD schema as a backbone to do the conversions and it was more flexible, robust and scalable than its predecessor which used XSLT. The financial documents were in the proprietary FpML-like format.
• Used AWK to aggregate flat multi-dimensional trade risk curve data from several Excel spreadsheets and put them in the intermediate XML format. Developed and applied XSL template using XSLT to bring the data to conform to the company trading XSD schema, as per the client request.
