SUMMARY:

• I am a professional integration developer with Java development background.
• I have six years of experience in development and designing solutions based on Confidential DataPower. As an system integration consultant at Confidential, I integrated internal and external banking systems using Confidential Datapower, API Connect and Java microservices.
• In both projects Confidential DataPower acted as security gateway between external access (donors and hospital users) and internal systems.
• I have seven years of SOA based integration mediation development experience using both Confidential Websphere ESB and Confidential Integration Bus.
• My background is in Web Application Development, which allows me to understand complexities of web based applications including networking, firewalls, load balancers, application servers and databases. I participated in two main Java based projects: Account Management API and Document Versioning and Approval Application.
• Account Management API is a collection of REST based services used by web application for user identity management.
• The Document Versioning and Approval Application is a java based web application based on JSF, SEAM and JPA frameworks.
• For DevOps I have experience in setting up automatic builds and release deployment using Microsoft Visual Studio Team Services (equivalent of Urban Code).
• For application server monitoring, I have experience in working with AppDynamics agents for Websphere ESB, Webpshere Application servers and tomcat based servers.
• While working at Confidential, I learned using Rational Team Concert (Jazz/RTC) in collaborative software development.
