 As BizTalk Contractor, designed and developed two major e-Billing projects and currently involved in Reservation project.
 One of the e-Billing projects was designed to work dynamically based on the itineraries of the system that it is going to communicate.
 Whereas the other one was designed to work interactively through database-polling as it required more human intervention at various stages.
 As initial billing information comes as an Excel file, decoding of the same happens within the receive pipeline.
 Scatter Gather pattern has been implemented to deal with huge number of invoices within a batch. And aggregation pattern used to collect all the responses before updating the customised database that has all the Invoice information.
 SSRS has been used to generate reports that can be rendered as either PDF or Excel before sending them to clients.
 In both systems, invoices to the target systems can be sent as a batch or as one single item. Batching and De-Batching patterns were used.
 Communication to various systems were done through either FTP, SMTP, SFTP or WCF.
 BRE was used as part of the itinerary process to find out various elements (e.g. map and schema to use) dynamically.
 BAM was used to aggregate on invoice details for business use. And also used as a tracking tool.
 Developed a data service using entity framework (data-first approach) to be consumed by the admin site that administers the static data required by the e-Billing systems.
 Currently involved in a project to manage reservations. This is being built using micro sites on Azure and on premise BizTalk applications. I’m involved in developing BizTalk application that will receive client request and create reservation using web service.

 As a BizTalk Contractor my role within the Development Team was to design and develop BizTalk applications.
 During my period as a contractor I was involved in two main projects involving BizTalk.
 First one was to synchronize details and relationship of entities such as customer, company, site etc. within various systems such as CRM, Portal, Billing and CI.
 ESB Itinerary service was used for the routing purposes listening to a polling receive location.
 BRE within the itinerary service was used to make the decision on which systems to communicate based on the source and type of message.
 The other one was to manage cases and orders between the Portal and CRM system.
 Notification Service was used to snatch any case or order that comes in to portal database and route to BizTalk which then talks to CRM System. Likewise, any cases coming in to CRM System was polled and sent to Portal.
 Failure messages were stored in SharePoint for the Admin to fix and resubmit.

 As an Integration Service Developer, I was involved in building SSIS packages that collect various network data.
