Professional Summary: Stanley Healthcare Austin, TX Software Developer November 2014 - to Date * Vista Track and Scope Tracking system development at Stanley will be facilitated through a web based module which will be available from a central location in hospital and provides showing repots of products like dosage, exception, opened products, opened and expired after 24 hrs. Products used and charged to patients etc. used in hospital. Scope Tracking objectives are to track the scope as a physical asset, safeguard from theft/loss in hospital misplacement. Correlate individual Scope usage to patients, procedures etc. for incident notification and to track the movements of the scope storage or to reprocessing back to storage and to track handlers, monitor and enforce certain aspects of the workflow to promote policies and reduce damage to these fragile devices. Responsibilities: * Involved in client requirement gathering, analysis& application design. * Used several design patterns like Singleton, Factory, Data Access Objects and MVC. * Used UML to draw use case diagrams, class& sequence diagrams. * Modern IDEs like Eclipse and version control systems like GitHub * Developed presentation layer using JavaScript, HTML and CSS, Business Logic using Session Beans. Developed test cases using JUNIT. * Implemented client side data validations using JavaScript, server side data validations using Java Beans, Views using JSP & JSTL1.0, code MVC2 framework using JSP's JavaBeans & Servlet, Entity Beans for Object Relational mapping. Implemented Service Locater Pattern using local caching. * Exposed RESTful Web Services using Spring REST Controllers. * Worked with SOAP protocol and also resources using REST API. * Involved in fine tuning of application and thoroughly involved in testing phase and implemented test cases using Junit Handled the development of Entity Relationship Diagrams using Rational Data Modeler. * Architecting various Business Layer and Data Management components of this N-tiered and multi-tiered web based system over J2EE architecture * Translate application storyboards and use cases into functional applications. * Design, build, and maintain efficient, reusable, and reliable Java code using Java 8. * Ensure the best possible performance, quality, and responsiveness of the applications * Identify bottlenecks and bugs, and devise solutions to these problems * Worked on Angular modules and few front end frameworks like Ecma Script 6 (ES2015+), Typescript & Babel, ES6. * Advising new businesses on formation of corporations and business structures, drafting privacy policies and structuring commercial transactions. * Managed to get overall client satisfaction for the company with the entire withheld project with timeliness and perfection. * Handled the project as a lead QA tester, overseeing quality-assurance testing and teams for client software and systems development projects. * Performed system, unit, performance, load, regression, stress and data interface testing. Provided client developer teams with detailed reports on quality metrics, identified bugs/flaws and recommended fixes. * Designed and implemented automated testing tools and programs addressing areas including database impacts, software scenarios, regression testing, negative testing, error/bug retests and usability. * Documented software defects using bug tracking system and reported defects involving program functionality, output, online screen and content to software developers. * Delivered thorough QA testing reports that determined product quality and release readiness Agile methodology using Scrum.
