 ‘Connect’ Product Development

Connect is a web based application that provides reliable and cost effective messaging solution along with sophisticated any-to-any document translation capability, designed to handle both EDI and XML technologies interchangeably in one environment. This product is being used by top OEMs, Suppliers, Healthcare providers and Physicians.

Key Achievements:

• Involved in preparing Functional Specifications, Data Flow Diagrams and Data Modeling.

• Prepared use cases, design documents and assisted in framework determination.

• Modeled various parsers, splitters and packagers for processing EDI transactions.

• Enhanced the existing metrics reporting tool by replacing Crystal Reports with JasperReports.

• Designed DataAccessObjects, to connect business logic with database using Callable statements, Prepared statements and Stored Procedures.

• Integrated various applications through Webmethods Integration server. This includes developing WebMethods flow services and java services to communicate with MQ, HTTP server etc. Also involved in developing listeners, schedulers, watchers and data change triggers.

• Assisted in deployment of components with compliance to change control procedures.

• Created several simple and complex stored procedures and functions in PL/SQL and optimized the existing ones for better performance.

• Provides maintanence and support for the ‘Connect’ product. This includes administrating OFTP channels via RVS middleware system.

Environment: Java, Oracle 10g, JasperReports 3.0, XML/XSL /XSLT, WebMethods 6.01, MQ Adapter 6.5, Sun Solaris (Unix), Windows XP.

 HealthCare Information System

This system provides an on-demand service that enables information exchange between care delivery system and external points which includes Hospitals, Physicians and Providers. All services have been implemented based on SOA architecture in a Cloud Computing platform.

Key Achievements:

• Implemented various remote services based on Service Oriented Architecture (SOA) to communicate with Health care Portal applications. Remote services were designed based on Spring HTTP invoker and Hessian.

• Designed and developed a Cross walk system for West Tennessee Health care and Jackson clinic to share their Patient Ids.

• Solved the work flow of Patient Synchronization for THUMB Health Information System(THIS) by architecting a new composite custom service. This design gave an alternative approach to process EDI transactions.
