Client: Advanced Communications Services, Portland, OR 05/2012–PresentRole: Sr. Web Developer Project: AnalyticTool: role control and user privilege

Advanced Communications Services, Inc. provides a wide range of Voice, Data, and Audio & Video Services solutions for companies both large and small. The goal of this project was to improve and reorganize the backend management web application which was generally comprised of three parts:

1. Data retrieval - Retrieve & show client information and technical data.

2. Role control - Different users have different roles and all have access to different data and functions.

3. Data post - Data can be posted to server via designated components.

Responsibilities:

• Read and modified code in a multi-tier architecture with over 100 files. Re-organized part of the system , integrated it into a sub project with MVC (AngularJS) and created views to hook up Models to the DOM to synchronize data with server as a Single Page Application (SPA).

• Designed and developed data retrieval and data post pages with JavaScript, HTML5, CSS3 and jQuery. Created layouts adhering to “separation by functionality” rule.

• Used AJAX and JSON for massive data transfer between Client/Server. According to different component coding structure, AJAX calls were consumed by XMLHttpRequest object (JavaScript), load/ajax methods (jQuery) or $http service (AngularJS).

• Achieved role control functionality mainly by retrieving JSON data from AJAX and combining the retrieved data with jQuery to manipulate nodes in DOM tree.

• Utilized a combination of regular expression and jQuery Validation Plugin to conduct input check.While in the newer sub project, conducted validation in AngularJS way.

• “Data post” functionality involved some back-end work which needs “coding through” all related modules from JavaScript layer, Rest/Spring layer, Model DB layer and HBase.

• Used Bootstrap and media queries to make data post and data retrieval components responsive. • Worked with source version control tool SVN combined with MobaXterm to manage the code

repository.• Collaborated with QA team for bug fixing and functional/user-friendly improvements. • Developed test cases and performed unit test especially in AngularJS using Karma.• Day to day tasks related to website maintenance such as updating contents, improving user experience,

etc.

• Maintained, enhanced, and recommended solutions that suit business and technology needs from UI standpoint.

• Communicated well with Project Managers and other developers to proactively meet needs as indicated. • Dealt with cross-browser compatibility issues especially for old browsers like IE 8 and IE 9 which were

used much within company.
