Fannie Mae (Herndon-VA)
Creation of the Collateral trees for the megas and the remics, to enable identifying the unique backing pools of the megas and the remics. Data transfer to the central data warehouse of the final list of backing pools and their contributions for the current period and generating reconciliation reports for the same..
The same data used for the report is made available to users through a Front End application designed to allow users to make adhoc queries on the collateral tree information and the list of backing pools This applications uses SOA principles in the design and the data is accessed thru webs services in the systems that provide the report data. Also this GUI application uses Adobe Flex for the Front End and BlazeDS at the backend for data access.

Liquidity InformationReports 12/08 – 06/09
Fannie Mae (Herndon-VA)
Creation of the Liquidity Report Data by accessing the relevant data entities from 4 different systems (database servers) and producing a generic report (using Jasper)on a daily basis.
The same data used for the report is made available to users through a Front End application designed to allow users to modify the report parameters to produce variations of the report and analyse the same. This applications uses SOA principles in the design and the data is accessed thru webs services in the systems that provide the report data. Also this GUI application uses Adobe Flex for the Front End and BlazeDS at the backend for data access.
Flex is used in this project to provide an enhanced user experience, unlike what the customers are used to so far (with Swing and JSP). The page refreshes are gone and the data is what changes on the screen. The use of effects and transitions provides a greatly improved experience and the user has the options to tweak the parameters and drill down to achieve a greater granularity as needed. We are currently demoing the initial versions of this project to other teams interested in having a similar approach to their user interface applications. Also the Webservice approach has found traction as the various backend codes are being converted to provide open APIs for easy access by these and other systems.

Flex Projects for small clients 01/08 – Present
Freelance – Telecommuting (Herndon-VA)
Converted most of my earlier apps done with ASP, ASP.NET, AJAX to Flex for existing clients. Also I had the opportunity to work on a few new projects in Flex . Some were prototypes and the others were systems that went into production. I have used the latest arrivals in the Flex arena for these projects, to provide the best user experience and also to learn about them.
Following are some snapshot views of some of the Flex apps I have done in the recent past.
Recently I developed a dashboard interface as part of a prototype for a proposal to DCRA (District of Columbia – Regulatory Affairs). This dashboard is an extension to the Business Intelligence Suite from Pentaho using the xaction data files that Pentaho generates. The prototype can be viewed at
http://members.cox.net/athiagarajan/DCRADashBoard/DCRADashBoard.html
Here is another one – using static data to feed the charts but will eventually get the data from a backend database dynamically.

The next link shown below is the one we have now deployed at DCRA (District of Columbia – Regulatory Affairs) – the link shown is actually the final version on our development server

The latest is a prototype (proof of concept) for a potential project for a Virginia based firm – using Degrafa Libraries for vector graphics in Flex – link shown below
http://members.cox.net/rthiagarajan/BAEMapDemo/BAEMapDemo.html
Also currently I am helping my son revamp a PHP-MYSQL system into a FLEX based one – which they use at school to collect and list details (test SAT/AP/PSAT scores, extra curricular activities and colleges applied) of all the Seniors. We are also developing a new Student Directory app to replace the book version – with features like Yahoo Map and Ribbit interfaces
The initial version of this project for entering details about High School Seniors (test scores, college app status)
http://www.kavitech.com:8080/EduInfo/Destinations/Destinations.html# (login id guest, password guestpwd) (project for TJHSST)
Also currently adding the Ribbit Phone component to my earlier Video Rental App (done in Flex) to help the customer call clients about overdue issues and sales promos – by clicking on the phone number links on the forms. This requires having a microphone attached with the system. We also plan to use the application (with Ribbit component) to leave voicemails automatically for selected clients when there are new arrivals.
Also currently trying out Flex and Cloud Computing with the help of stax.net (www.stax.net) currentlyby putting some of my apps on that site.

Restatement efforts - Data Warehouse Creation (01/07 – 12/07)
Fannie Mae (Herndon-VA)
As lead architect planned and executed the project to ensure that the latest and relevant data from the Bond Administration system was passed on to the central data warehouse. This involved transferring information about new data, updates to existing data and details about deletions. The transfer happens at various points in the business cycle, to ensure a that warehouse data is synched up at all times to reflect the latest position on the Bond Administration side. Involved assessing the data elements that needed to be passed to the data warehouse, ensuring the data providers and the periodicity, plans for generic code for easy scalability and maintainability, strict audit controls for ensuring that data transfers were error free.
Additionally built new collateral tree data info for the restatement effort to help the regulators have access to historical data for audit purposes. This involved writing wrappers to existing code and data to transform the data into other forms which made sense to the regulators/auditors.
The collateral data is made available to other systems through web services. These applications use SOA for their architecture.

Video Rentals and General Provisions Inventory Application (01/07 – 12/07)
(Herndon-VA)
The earlier Video Rental App was enhanced to have an AJAX approach for the front end. It was also beefed up to handle the inventory of general provisions in small retail stores which had sales of general provisions along with video rentals. The same data base was used for both the combined apps. The details of both apps were used for the combined reporting on common customers. This was a single page app with communication to backend only for data. XML was used for data transfers and SQL DB server with ASP was used in an IIS server at the backend.
Windows XP, ASP.NET, AJAX, MSSQL
Accounting Interface/Bond Admin Control System Phase II (01/06 – 12/06)
Fannie Mae (Herndon-VA)
As Team Lead and Architect for the transfer of the accounting data from the structured transactions of the Bond Administration system to the General Ledger Accounting System. The project involved extracting the financial details – amounts paid and received, both actuals and expectations, from the Bond Administration side, available on Sybase databases and pushing it across to the Accounting Systems residing on Oracle databases.

Doctors Office – Appointments and Claims processing Application (01/02 – 12/05)
(Baltimore-MD)
Worked on a base web app package with specific features for application to handle Doctors office operations like appointment handling ad claims processing. This package was done for a specific client in Baltimore. The system had capabilities to take care of multiple doctor’s (providers) appointments and transmission of the claims from the provider to the insurance carriers. Lots of reports and document printing features along with queries were provided. The system was done in ASP (with XMLHTTP objects – precursors to AJAX technology). This was a single page app with communication to backend only for data. XML was used for data transfers and SQL DB server with ASP was used in an IIS server at the backend.

XML/Proprietary File Import-Export System – Loan Prospector (03/01 – 12/02 )
Freddie Mac (Tysons-VA)
As a Senior Technical Lead - developing a Sub Module for importing (uploading) the loan details (in XML and other proprietary file layouts) and exporting (downloading) the results of the loan scoring process (in XML and other proprietary file layouts). Developed Translator engines to convert from one form (loan model) to another within the Main module. Also assisted in the development of code generators for producing code for DAO objects to be used in the system. The system was developed using Weblogic with the translation engines being embedded in the Session beans. Also provided assistance in developing testing code (JUnit/HttpUnit) for most of the backend modules. Developed the front end code in JSPs and Java servlets for the uploading/downloading of loan info/scoring. The system is going into production replacing an existing system in July 2002. It will support the XML layouts for loan data and feedback transmission as agreed to by Fannie Mae and Freddie Mac and detailed by MISMO.(see www.mismo.org) The system also has provisions to support proprietary layouts by Fannie Mae and HUD. The core module is designed and developed to convert as B2B Hub providing web service features like loan scoring, pricing etc to all forms of client systems supporting different transport protocols and messaging services.
Currently being prototyped to provide the services using SOAP and WSDL as WebServices and WebMethods is being proposed for use as the EAI tool.
This system as well as some of the earlier projects (done by me) talk with other systems for acquiring data relevant to their process through proprietary code ( home grown adapters and integration software ) . Effort is underway to study and replace most of these with EAI tools like WebMethods, to have a consistent approach across the enterprise, for application integration and workflow.
