The applications were written in Java and used MyBatis as the persistence framework and Flatworm to read incoming and generate outgoing Remittance data.
Developed, deployed, and maintained a multi-vendor pension loan repayment system based on Automated Clearing House services provided by Wells Fargo. The application was written in Java and used MyBatis as the persistence framework and Flatworm to read incoming and generate outgoing loan repayment data as well as read and process subsequent incoming confirmation data.
Wrote a Java-based web service to process payroll remittance uploads from a fellow retirement solutions provider that merged with the company. These services were deployed on Tomcat and used Apache CXF, Spring and Hibernate. As such, the solution was completely open source thereby providing a significant savings to the company without compromising availability and reliability
Senior Software Consultant, Credit Suisse (Sep 2008 – Dec 2008)
Senior consultant on the PrimeTrade project. PrimeTrade, developed at Credit Suisse, is their web-based electronic trading platform for security products.
Designed and wrote code to add the functionality to import orders from a file to trade in the Click and Deal (SER - Streaming Executable Rates based on rates returned from the EFX (Forex rates) servers) panel.
The import dialog allows the user to populate an ‘Import Blotter’ table with orders contained in a .csv file. In the new dialog the orders may then be executed so that they move from the ‘Import Blotter’ to the Order Blotter.
Unsuccessful orders may be exported to a .csv file which may then be corrected and ultimately (re)imported.
The orders to be imported will be limited to those containing booking accounts in PrimeTrade and valid currency pairs for the Click and Deal trading.
The ability to import files will be limited to those users who possess the entitlement to do so. This entitlement is controlled through the property file value.
The core coding was done in Java and Java Swing and was multithreaded.
Senior Software Engineer, AxisPoint, Inc. (May 2008 – July 2008)
Senior software engineer on the Works project, a multithreaded Java/Swing/Oracle music publishing application developed for a major client, an international music publisher.
Associate, Information Technology Department, Morgan Stanley
(April 2006 – Dec 2007)
Senior developer on Turnover Change Management system (Tcm2), an in-house system built to facilitate Company-wide SOX (Sarbanes-Oxley Act of 2002) compliance.
Tcm2 comprises a backend Soap server and a front-end web GUI both written in Java. The front-end is managed under the web farm, and utilizes all the standard MSJava toolkits (internal java wrappers). The backend interacts with a Sybase database to store requests and is capable of responding to requests via Soap messages. Almost all actions provided by the front-end GUI can be achieved by making Soap calls directly to the backend server. Other systems are expected to interact with the backend directly to manage TCM requests. There is also a client API provided in Java to facilitate such interactions.
Was the original developer on the server side, which is a java-based Soap server that acts as a client to other Soap servers, through both java and perl-based Soap Api’s.
Senior Technical Specialist, Global Derivative Systems, Salomon Smith
Barney/Citigroup (Aug 2003 – Mar 2006)
Senior developer on Java-based fixed income derivative trading system built on top of the distributed RMI-base Calypso framework and running on Solaris with Sybase backend.
Wrote the Sales Allocation subsystem to allow salespeople to suballocate a block trade into child trades. This was a swing application partitioned into a model, view, and controller for ease of maintenance, and was a part of the Sales Trader Matching system that allows salespeople to match sales trades with trades entered by traders, and conversely.
Wrote the Bond Blotter application, which replicated existing functionality for creating bond prices in a user friendly Swing application. Formerly, the desk used a spreadsheet to determine bond prices.
Wrote the Credit Default Swap Wizard, a swing application, to enable traders to enter and modify trades more conveniently than from the base Calypso system. Traders can create templates that automatically supply defaults for most of the trade components and can configure lists of favorite values to be used for populating list boxes for trade components.
Wrote the Credit Option wizard, a screen to enter and modify options on Credit Default Swaps.
All wizards were written in Java swing and were multithreaded.
Designed and developed programs to reconcile transactions and payments with the legacy back office Oasys system via a third system written in C++. This necessitated the writing of a JNI adapter.
Also wrote batch programs to update reset rates from the Oasys backend system, to update and save CDS curves, to perform bond calculations as well as other bond blotter operations in an automated batch setting, and various other smaller batch applications.
Wrote CGI scripts in Perl to enable web access to various generated reports and configurable Perl scripts to ftp various files to the web server report directory.
Senior Consultant, Fitch Risk Management (Feb 2002-Aug 2003)

capital at risk values. It also saves runtime state when in batch mode, allowing for a hotstart when run subsequently in interactive mode. Created reusable class to support dynamic addition of columns to Java Swing Tables. Created Java Swing infrastructure to allow easy addition of cut/paste and print functionality.
Implemented infrastructure to limit memory usage for very large number of run scenarios.
The entire system was developed in java/swing and configuration management and state persistence was in java/XML.
