Project: Install-io - Software/Content Deployment toolHIUI (Health Care Intelligence User Interface) is a single point of entry for clients to use current and future BI (Business Intelligence) applications like KPI (Key Performance Indicator), BO (Business Objects), AL (ANALYTICS LIBRARY) etc. HIUI also provides content in the form of CARDS for individual apps. Install-io is software/content deployment tool for onboarding clients into HIUI, built on MEAN stack and follows NPM package structure. Components of Install-io are Reactor - Deployment Agent, Conn - Web app allows to monitor the onboarding process, live logs etc. and Data Store - MongoDB as a central data store for reactor and conn.Responsibilities:Developed Search Bar on Job-status Page which decreased page load time and improved performance by reducing the number of API calls made to the data store.UI for the conn page was developed using HTML, CSS, Bootstrap, AngularJs, and checks in the validation layer to ensure Client Information is valid before onboarding.Used Angular Material Design to display validation results in dialog boxes for onboarding jobs.Used Express.js for setting Routes for API's to perform CRUD operations on MongoDB collections.Used Node.js to develop modular server-side JavaScript Packages to perform operations like Installing certs, adding Application Pools, setting Virtual Directories in IIS and setting up Tomcat properties to deploy BI applications like AL (Analytics Library) etc.Used JASMINE for testing server side Node.js packages and client side AngularJs packages.Designed Mongo Queries to retrieve data from Mongo Collections and Used Mongoose to create Models, routes for API calls to get the data from MongoDB.

Mozido offers mobile commerce technology solutions for mobile network operators, financial institutions, card issuers, and retailers.

Used JavaScript, jQuery for validating the input given to the user interface(UI) and Involved in designing test plans, test cases and overall Unit testing of the system.

Polaris is a global billing integration project for Rackspace to bring all billing systems under a single hood. There are multiple modules under Polaris among which BSL and Payment Service are main components. BSL (Billing Service Layer) is a billing component, which uses Oracle BRM as the main billing engine. Payment Service is a payment gateway for Rackspace, which talks to Chase ORBITAL for handling payments.Responsibilities:Developed Backend services using Spring, RESTFUL Web Services, Hibernate. Used Jackson and JAXB for generating XML and JSON parsing.Developed REST API for BSL and Payment service using Jersey and Spring framework. Enhanced API's in payment module to propagate audit information to BRM and disable payments.Designed and Developed REST API's in HATEOS model to integrate with LYONS data APIs for deriving bank name from routing numbers.Created ORM mappings for tables to store bank names and other details using Hibernate. Used Mockito framework for JUnit tests.
