Project: VISA Modernization – PF3 Replacement Design

Role: Technical Architect

This project involved the modernization of an application, which was implemented using COBOL, Mainframe and the IMS database. The VISA application in FedEx was used to add, modify, delete and view FedEx Air Waybill information. A FedEx Air Waybill captured all details about a FedEx shipment – the sender, recipient, description of contents, whether the content was hazardous, weight, size etc. FedEx wanted to move away from the Mainframe environment and move towards a modern web-based architecture for VISA, which would enable the VISA application to be accessed from any PC, mobile or handheld device. The scope of this project was to document the proposed User Interface and the Technical Design for the new web-based system.

Responsibilities:

●Technical design and documentation of the proposed new web-based system for VISA. The new system would use JEE as the platform along with Spring on the middle tier and Spring Data on the ORM tier. It used Jersey, HTML 5, CSS 3 and AngularJS on the presentation tier.

The middle tier used the micro-services design, to transfer data to/from the HTML clients. Additionally, Tibco’s ActiveSpaces distributed cached was used to cache data on the middle tier, to improve performance.

●Had discussions with the FedEx architects, to discuss various candidate architectures for the new system and narrow them down to two candidate architectures for the new system.

●Documented the architecture using the 4+1 view model of software architecture. Used the logical and physical views to depict the chief architectural components.

●Low level design and documentation of the new system. The low-level design carried on from the high-level architecture and documented the dynamic and static aspects of the system using sequence diagrams, class diagram and data flow diagrams.

Project: Webtag Resiliency

Role: Senior Java Engineer

The Webtag Resiliency project was basically concerned with providing the ability to failover to an application called Webtag. Webtag was a JEE application, which was responsible for the distribution of reports written by analysts to various parties, who were interested in viewing it. Since it was very critical that the interested parties got the reports on time and without disruptions, hence it was essential that Webtag experience close to zero downtime. What was needed was the ability for a parallel, running, secondary Webtag instance to take over the processing from a primary Webtag instance, which had failed suddenly. Since Webtag was deployed on Weblogic and used the file system and a database to store files and data respectively, the goal was also to provide a secondary file system and database, which could be used, in case, if the primary ones failed.

Responsibilities:

●Authored an architecture document, which proposed a way to provide transparent failover from a primary Webtag instance to a secondary Webtag instance, which was running on a different application server and using a different file system and database.

●Designed and implemented a prototype as a proof of concept for the architecture. Conducted performance testing using the prototype.

●Responsible for creating a local development environment for the application by mocking up external stimuli.

●Responsible for the configuration and deployment of the application using a multi pool. The multi pool was configured for fail over in which the failover database server was continuously synched up with the primary database server using replication.

●Redesign and modification of the webtag application in order to provide failover capabilities to the entire webtag application. Redesign involved checkpointing the state of the application regularly to the database.

●Responsible for the introduction of the Spring framework, JPA/Hibernate and Struts frameworks in the application. The earlier application used EJB 2.0 beans, JSPs and Servlets.

●Created and configured Struts’s struts.xml, Spring’s applicationContext.xml and JPA’s persistence.xml file to configure the presentation, middle and ORM tiers.

●Contributed to the support, maintenance and bug fixing of the application, while it was deployed in production.
