Senior Java developer

Responsibilities:

• I’m leading a team that is responsible for a product called EPCS which serves big customers like CVS, Medco, Omnicare, etc.
• I single handedly did Tech Stack refresh in EPCS environments for which I upgraded JRE, Tomcat, Apache, updated code base with latest Java 8 libraries in a short span of time.
• In UIS I’m responsible for Triaging production issues, delegate and co-ordinate with multiple internal teams, provide solution, develop features and resolve complex issues.
• Worked mainly in a module responsible for capturing user authentication transaction information and generating report out of it. Managing thousands of users at the same instance was challenging as every transaction will be having different states.
• Handled this problem effectively with the help of oracle coherence to store intermediate states of a transaction in Coherence Cache without persisting. Used Oracle OLT and JRockit Mission Control to find and fix performance bugs.
• Successfully did a POC on MIME for one of our Messaging application.

Environment: Java 6 & 8, Oracle 11g, Hibernate, JUnit, Maven, Jersey RESTful, HTML, JQuery, Eclipse, SVN, WebLogic, JMS, Oracle Coherence, Nexus, Jenkins, Quartz Scheduler, iBatis, MIME, Information Security.

• Worked as a part of system redesign team, responsible for converting this 15-year-old application to new UI format.
• Employed new front end technologies to effectively transform the system. Moved all business logic from JSP to Java based servlets.
• Rebuilt UI with HTML5 and other Scripting frameworks AngularJS, HandlebarsJS, RequireJS
• Cleaned up the code base, removed deprecated methods and employed latest libraries.

• Developed custom pages in SalesForce to meet business needs with VisualForce and Apex. Used JavaScript to manage user actions, integrated it with the VisualForce page.
• Migrated data from old DB structure to structure that supports revamped page design.
• Successfully completed the assignment despite of the fact that SalesForce was a novice domain for me and it lead to opening up multiple SalesForce opportunities for my organization.

Environment: SalesForce CRM, Visual Force, Java Script, Apex Data Loader, Cloud Computing.

Java developer

Responsibilities:

• Formulated the system design and implemented it single handedly right from gathering requirement to hosting the product in cloud.
• This is where I gathered experience as a DevOps engineer, since I architectured the system, created project base, built a CI set up with Jenkins.
• Integrated the system with a third party service provider TMDB and hosted it in AWS EC2.
• Compared multiple cloud computing infrastructures and chose AWS, hosted the application in EC2 single handedly, used EBS for data storage.
• Used Quartz Scheduler to synchronize data with TMDB periodically
• Chose MongoDB as data storage as the application requires to store huge amount of data and there is not going to be much of a dependency between the objects.
• Used Spring Mongo DB as the ORM Framework.

Environment:Java 7, Tomcat, MongoDB, Spring-MongoDB, Quartz Scheduler, Jersey RESTful, Maven, Subversion, CVS, Junit, JSON, AWS, EC2, EBS, Cloud Computing, JSP.
