PROFESSIONAL EXPERIENCE

Confidential, Columbus OH

Web Developer

Responsibilities:

• Worked on a web project which used AngularJS and Bootstrap on the front-end and MySQL as the database. The CRUD operations were done in LINQ, and it utilized the REST protocol as the communication medium between the database and the controllers.
• Worked on a project which upgraded a client’s current Java programs, which were written using version 1.3, to Java 6. Also upgraded their EAR and WAR projects, which targeted WebSphere Application Server v5 as the deployment server, so that they are compatible with WebSphere Application Server 8.5. Went through all the code to identify and recommend re-write opportunities, and eliminated most of the warnings generated mostly due to lack of use of generics types and unused variables.
• Working on a web project which utilizes the DevExpress controls and data source objects. It uses Bootstrap and HTML 5 on the front end with a SQL Server database. It also utilizes LINQ for the CRUD operations.

Confidential, Columbus OH

Programming Analyst

Responsibilities:

• Worked on an in-house web application using Struts 2, Spring, and traditional web technologies (e.g. CSS, JavaScript, jQuery). Also implemented several functionalities of the application using other frameworks. For instance, generated customer emails using JavaMail and TinyMCE APIs; generated in-house reports in Excel using the Apache POI API; and implemented date time pickers using Struts 2 jQuery and Dojo plugins.
• Written stored procedure and functions using T-SQL.
• Setup Hudson to automatically build, test, and deploy application to Tomcat servers in Linux environments.
• Written unit test cases using JUnit and mock objects using Mockito.
• Written shell scripts to manually deploy web applications to Tomcat server on Linux for DEV and QA testing.
• Coordinated with the network group to setup F5 load balancing and monitoring on PROD servers; and performed new application deployment to PROD servers.
• Created a web service client with AXIS for the data automation group to access public court records in Pima, Arizona. Wrapped the client in a Java Swing GUI and set up logging mechanisms through log4j.
• Created a Swing application for QA to load test the URLs generated by another web application. The Swing application, first, requests users to enter their username and password for LDAP authentication. Then, it provides another screen for users to select the file that contains the list of targeted URLS, and requests for other testing parameters (e.g. number of times each URL should be hit and the number of threads spawned for each URL hit). In addition to logging information, the application will return the response and process time of each URL hit or the reason(s) when an URL fails to provide a valid response.
• The same Swing application also allows users to request for information on DataVerify by sending multiple XML requests, through POST protocol, from its website in a batch process.
• Created a servlet that handles both Identity Provider (IdP) initiated, i.e., users log on at client locations, and Service Provider (SP) initiated, i.e., users visit the web application directly, single sign on (SSO) processes via PingFederate server as a proof of concept for the process. And currently working on implementing the servlet into web application.
• Created a simple proof of concept application that involves sending a message through a RabbitMQ topic queue, then transforming the message into XML, and saving it to the MarkLogic database. The file is then read from the MarkLogic database, sent through another RabbitMQ topic queue to a process that extracted the message, and saved the message to a file on to the local drive.
• Involved in the design process for the backend system re-write, and written up preliminary design document to explain the process to upper management and justify the new technology recommendations.
• “Mavenized” an existing web application which is ant-built with over 150 dependency library jar files; it also requires the creation of a bunch of Java stub files from an existing WSDL and copying a bunch of files from another project located in the SVN. Also working on updating all the dependency jar files and modifying the existing code for the backward incompatible classes from the jar files.
• Worked on compiling a list of files changed based on JIRA number from the SVN using the SVNKit and JIRA comments for each JIRA number using the JIRA Java API for each QA release into a file to be included with the release.

Responsibilities:

• Working on a project initiated by the TCGA program of the NCI which involves converting cancer patient study results in XML format into tab delimited format, aka “biotab”, using XOM, XSOM, and XMLBeans.
• Performed analysis on the biospecimen and clinical XML files, by disease study, in order to better understand the different requirements of the biotab files for each disease.
• Written a custom class loader to load the necessary classes from third party jar files within an executable jar file, and make a method call to the main class of the application using the Reflection API.
• Written an utility class to validate the date related data from the XML according to business rules and to generate data to obfuscate the patient identifying date related data.
• Writing a XML parser in JDOM to create new XML files with the obfuscated data to test the utility class.
• Evaluating Apache Camel and ActiveMQ to integrate the biotab file generating process from obtaining the XML files for processing to the bundling of the biotab files.
• Written a Java program to bundle the biotab files and cryptic-hashed the bundling files with MD5.
• Writing documentation for the biotab generation process, the date utility application, and the bundling process in Confluence.

• Worked with the UI and integration teams to perform service operation analyses on each business process model identified by the business analysts on the OWF project which has just been released to the clients of Confidential ’.
• Worked with data model domain experts to identify entities for each data domain and created entity classes and fundamental DAO operations (i.e., CRUD) using OpenJPA for each entity class.
• Written Groovy script to generate WSSE header in the SOAP request and destroy the header after receiving the response in soapUI in order to create an automated testing environment for each service operation. Also written Windows batch scripts and bash scripts on LINUX to run soapUI tests without the user interface; and written a Python program to generate HTML reports based on the results of the runs for the enterprise test team.
• Created WSDL and XSD for each service, generated the service skeleton beans using top down method; and implemented the logic for identified operations.
• Implemented DbUnit to test the DAO implementations and mocks via Mockito to test the service operations.
• Written several simple service clients in C# to test the operations in addition to using the soapUI tests.
