Responsibilities:

• Analyze current LB provisioning via SNOW(serviceNow) fields. Designed Input/output fields(schema) required for LbaaS.
• Created RestFul microservices from existing Maven archetype templates provided by Confidential custom RPP(Resource provisioning proxy)
• Created LbaaS Adapter Rest Service- consumer facing microservice.
• Created LbaaS endpoint Rest Service - a microservice that actually creates a Load Balancer in Netscalar device for a given DataCenter and Region.
• Created LbaaS schema (data/schema objects that are using by both adapter and endpoint for internal communication.
• Create OSGi bundle(kar file) via Maven and deploy on Confidential custom ESB, RPP platform built on top of Red hat JBoss Fuse6.2.0
• As functional tech lead, involved in design/POC implementations for HP cloudFoundry, and sampls apps using OpenStack API .

Technologies: RedHat Jboss Fuse 6.2.x/RPP( Confidential custom made ESB running on top of Jboss fuse). Core Java 1.7 IntelliJ15.x, Eclipse3.x, Maven3.x Github, Teamcity, Nexus Repository. Json Yaml( used only for building sample/POC apps)

Confidential, NYC

Senior Java/J2EE consultant

Responsibilities:

• Create implementations for new Services/Architecture blueprints. Involves exploring new APIs from Vendors(mostly IBM services) and integrate with existing Services.
• Created new RESTFul Service to get documents from Ondemand Server. This is part of migration project from Mainframe to AIX servers(backend) and migrating clients to new ICN (developed by other teams). My part involved in providing a stop-gap solution for BTS areas who still wanted to use existing Service. This involved in creating a REST service that would accept JSON object and return JSON as response. Response object contains a HTML with CSS, contains list of documents from Ondemand server with hyperlink that either can get the actual document from new ICN service or existing service.
• Created new ITIM Create user service that allows specific BTS areas to create users in TIM/TAM servers directly instead of going to manual process( send an email/servicenow request to backend teams)
• Created load test utilities using new Concurrent API(executionService and Completion Service) to emulate a load activity on ODService for performance tuning/analysis purposes. User of this utility can specify how many simultaneous requests they want to process with list of all folders. This utility would kick off that many calls to the service concurrently, collate results and print out times taken( it’s a non-ui Util).
• Involved in migration of all services from websphere 6 to websphere 7.5 platform( this project was already in process at the time of my starting at Guardian). Mostly involved in testing and coordination activity.

Technologies:Core Java 1.6(Multithreading using concurrent package, Data Structures(only Java )MQ Series 1.6, JMS, RAD 7.5/8.1, Websphere 7.xMakefile modifications for migration for token creation from mainframe to AIX. An exit program required by users to access the back end server.
