Fusion Company, VA - Sep 2008 to present

Travel Insurance Web Service

●Designed and developed the platform called TI2.0 (Travel Insurance 2.0) to support the market testing needs of the business. TI2.0 is a .NET based WCF service which picks up the optimal treatment for the end users, based on their profile, through the in-built rules engine and renders the insurance offers after formatting it dynamically. The database for TI2.0 is Oracle 10g.

●The output from the service is stored in the database and run through summarization process, to be presented as report to the Market testing and optimization team, for their analysis of the treatment performances and to start their next cycle of market tests

●The Rules engine is completely configurable with its expression builder to setup the business rules and Razor tags builder to setup the content (messages embedded within templates)

●TI20, being a mission critical web service, its performance is monitored 24*7*365 through TrueSight and AppDynamics, in order to adhere to the client’s stringent SLAs. The average host latency is under 100ms and the host latency at 99th percentile is under 800ms

●Being a critical member of Level-2 on-call support team, effectively monitored the service and assisted production support team (Level-1) on their day-to-day issues.

●Designed and implemented an application to check the health of the services. This application was setup to be pinged by NAGIOS monitoring system periodically and accordingly the health check alert emails are sent to the production support team.

●Working on implementing UNICA Rules Engine into TI20 service, replacing the in-built TI20 rules engine

●The DAL for TI20 uses NHibernate (ORM) to retrieve the data from the Oracle database and stores it in the thread-safe cached collections. These cache collections are refreshed based on the AppPOOL recycle settings. Once the cached collections are built, all the requests to the webservice are served using the data from the cached collection

●A seperate webservice (Data Persistence Service) was developed to persist the transaction data from all the requests. TI20 calls this webservice asynchronously to persist all the transaction data.

●The application infrastructure includes a caching mechanism, in which all the metadata are cached into the application’s memory and also gets serialized into JSON format and stored into cache file on the hosting application server. In case of database connectivity issues, the application cache is built using the data from the cache file.

●TI20 service was hosted on a web farm based infrastructure, serving insurance offers from 2 datacenters, load balanced in an active-active mode. The load balancing strategy used is ‘Least Connections’.

●Designed and implemented all the backend processes to summarize the transactions and to generate the daily reporting alerts, which the Market testing and optimization team uses to analyze the performance of their market tests (treatments)

●Worked on the datacenter migration/consolidation project, when the management decided to migrate from one data center to another as part of cost-cutting strategy. As part of the project, migrated TFS2010 from one hardware and another.

●Configured the TFS CI server and setup automated builds using TFS builds. Edited the visual studio XAML file to drop the builds onto development server. From the development server, the builds were replicated to QA and then to UAT servers and PROD servers using repliweb. This way, the whole build and deployment process was completely automated.

●Worked on refining and implementing the IT change control process.

Consolidation of Web Services

●The objective of this project is to consolidate individual webservices that were created to support individual insurance verticals, in order to support versatile functionalities from within same code base

●Configured application initialization module in IIS 7.5 and setup the cache refresh for the webservice through custom servicehostfactory

●Eliminated the use of host based service activation by using config based activation (CBA)

Dynamic Email prototype

●Researched and implemented a strategy to send dynamic contents to an email.

●This was done by sending an image in an email and having the webservice call through that image and hence passing a dynamic content as an image to that email, whenever that email gets opened

●This project was initiated to send the alternate products to our customers through email.

Product definition system

●Product definition system is a web application to manage the products that are offered and the message content that are configured through the optimization platform of Fusion.

●Some modules of the application are built using asp.net web forms and the other modules are built using MVC.

●The application was built with workflow and approval process to promote the data in a secured way.

●A separate WCF service was built to promote the approved data to subsequent databases. The web application would call the sevice asynchronously to do the data promotions.

Metadata migrator

●Designed and implemented an application to migrate the metadata (business data) into QA databases to support their testing needs.

●This application was built by calling an oracle stored procedure, which copies the data and sync up the Ids based on the sequences from the prod.prestaging database to all the QA databases.

●Oracle dblinks were created to support the data copy.

●The front end was as web application developed using ASP.NET MVC 4.0 framework

Documentation Automation using SHFB

●Automated the generation of documentation from the source code comments using SandleCastleFileBuilder (SHFB)

●Installed and configured SHFB on our TFS Build Server

●Integrated SandCastle project into the Solution in Visual Studio

●Configured the build process steps that enabled the checked-in source code comments to update the documentation automatically through automated build process

●This kept the source code and its documentation in-sync at all times

Supplier Integrator

●Designed and developed an API to integrate with product suppliers for Fusion.

●The API was developed in a generic way to be able to communicate with any product supplier of Fusion.

●The integration is through a workflow model - Validation through a configurable rules engine, Formatting the request and response structure through RAZOR engine compilation, communication through HTTP POST using HttpClient Class

●Used Microsoft Cryptography assembly to encrypt PII data.

●The appsetting entries in the web.config file were also encrypted for security reasons

●The application is made into 3 tiers - External service interface, middle tier implementing the configurable workflow, Data access layer; Two different service interfaces were developed - one with RPC using ASP.NET WCF framework, other one with REST implementation using ASP.NET WebAPI framework

Widget Integration with BookIt

●Developed Widget library using JavaScript and jQuery to integrate with BookIt.com

●The integration is by BookIt.com calling the functions in the library in order to invoke the widget

●The functions in the library internally make AJAX calls to Fusion’s optimization service to get the HTML blob to be displayed on the partner’s webpage, that was reserved for the widget

●The content is delivered through CDN from Akamai.
