PROFESSIONAL EXPERIENCE

Confidential, Dallas, TX

Sr. Software Engineer

Responsibilities:

• Performing production support by writing complex stored procs using provided business logic to process data and preparing reports for Sr. Managers decision making; make enhancement for canned reports, and running ad-hoc T-SQL queries accommodating daily requests from customer care departments; creating views and indexes, and revise cursors in optimizing the performance of reporting system.
• Working alot on legacy Java applications re-writing and packaging business functions/business logic classes into companywide libraries, using Java OO architecture and design, integrating into current major projects.
• Writing JUnit tests for each every java objects (TDD) to ensure full coverage on our development codes.
• Writing JBehave Stories for automated UI components functions testing (BDD) by binding the RESTful live service call with GUI components.
• Implementing SOA namely air-operations client (flight-schedule, flight-status) RESTful service to call AIS(ALTEA Information System), to Get Client/Resource, using AOP for managing final error messages in the returned Response object (JSON file), using JSR hibernate validator annotations for input fields validation, using MounteBank for managing stub data by using Unix/Linux shell scripts to directly populate the imposters (the other approach of implementing individual stub resource builder for each every module is overkilling and expensive as of now).
• Following Agile/Scrum methodology, involving every sprint planning, requirement reviewing, story complexity evaluating, sub-tasking, and implementing the project within sprints as planned. In most cases, when stories do not have a clear scope or a moving target to achieve, will perform spikes for pre-task evaluation to provide achievable solutions.
• Performing peer code review for team members before checking code finally to merge to trunk by following the best practice of clean code.

Environment: Apache Tomcat web application server, Linux/Unix OS, SQL-Server & Sybase, Spring (MVC) Framework, Gradle build project, Jenkins and Jira running in a Linux environment; paired-programming, IntelliJ IDEA, Core Java (multi-threading/Concurrency), Maven2, TDD, BDD, JUnit, in an agile environment utilizing Git.
