North West airline has an in-house Self Service Device (SSD) product development, there are kiosk machines that are placed in the airport and help the passengers to check-in into aircraft without manual intervention. I was part of the software re-architecture work for the SSD team to re-write the product in N-tier J2EE and SOA architecture. The product exposes various business components as web services to the external applications. These web service components are developed using SOA principles. Agile practices such as iterative development, continuous design, test driven development are practiced throughout the development. I was also part of the internet check-in re-architecture work where the entire codebase from SSD was re-used to implement the internet check-in module.

Role: Technical Lead

Responsibilities/Achievement:

• Architecture direction, Design/development/Testing/Implementation of various system components
• Led the effort to design a SOA/Service module which exposed a set of services
• Led the effort to re-use the code base for internet check-in module.
• Mentoring of other team members
• Production trouble shooting and implementation
• Architected, designed and developed web based management software, which allows the business users to update various configuration files.

I have worked on an EAI (Enterprise Application Integration) product, developed for FedEx to integrate various products developed in different platforms. Integration is achieved through a middleware, which was a configurable component in the System. Some of the products got integrated were AOM (Warehouse Management System), EXE (Order management system), GIV (Global Inventory Visibility), PowerShip, FedEx Net Square. A number of Business messages flow into the system like Sales Order, Purchase Order, Warehouse Receipt, Product Master, stock Status etc. The messages get converted into the different format needed by the target system. The integrated components are driven by generic workflows or business-flows defined in the database.

I have also worked on another Software application that is the implementation of ECCS (Electronic Commerce and Customer Service, A division of Federal Express, USA). This application has a client server architecture, which uses VB5.0 as Front End. This Application runs on Tandem Hardware, uses middleware RSC (Remote Server Call) to communicate with the backend Tandem-C and Cobol Servers.
