Experience

Software Engineer J2EE,

Confidential

Responsibilities:

• Designed Complete TCDMS application as pluggable modules that works on REST implementation. Main modules of the system are Core-TCD, P6Module, and CM-Module.
• Core-TCD is built with Spring MVC REST implementation and extensively used design patterns like Builder, Composition and Aggregation to build the complex objects of Subdivision which holds various objects of Train Control Data Management System. This module integrates systems like EFMS, WIU, Signal CAD systems using schedulable jobs. Data is normalized and validated and generated CCLs custom xml to support generic PTC data model for various TCD features.
• CM-Module mainly designed to perform and keep track of the changes implemented on PTC Track. Every Track change will be tracked though this module. This module internally uses P6-Module and inbuilt workflow system to escalate issues while implementation in all the phases of Track Profile changes.
• P6-Module designed and implemented to integrate Project Management tool P6 functionality into TCD project. Oracle Primavera P6 is integrated through its web service API to create and modify Project, Activities, Activity Codes, Resources, EPS, and WBS along with Scheduling of the Project is implemented by considering the SLA of Project and Activities in addition to Re-Planning Release feature.
• Core-TCD Module is designed as deployable module to any Web Application containers along with CM-Module and P6-Module as executable java archives.
• Core-TCD performs all the request processing related HTTP and JSONs with the help of spring framework Jackson JSON library default converters.

UI and GIS Maps Design

• UI is designed to run on static server which is de-coupled completely from the back end Java server and independently deployed on the Apache server.
• UI is built with Angular-JS, JQuery frameworks and JQuery plug-ins like UI, GRIDs, validation, widgets, HTML5, CSS3.
• UI built to interact with backend in AJAX way using JSON formats for request, responses.
• GIS view is built with ESRI JavaScript Web API, JQuery and DOJO frameworks.
• Base Maps are designed from ESRI online services. Base Track layer and infrastructures related layers are built with Restful services and loaded on the Map as Overlays.

Environment:

• JDK 1.6, Spring 3.2, xml beans, JBOSS EWS, STAX Parser, Angular-JS, JQuery, ESRI JS-API, HTML5, CSS3, JSON, MS Visio. Maven, SVN, Oracle P6, Eclipse 4.x, Oxygen, Jenkins, Star UML and Mockito Junit framework.

• Generated the shape files from ArcGIS 9.3 server to build back ground Maps like, Regions,
• Queries and filters of Arc Catalog, Arc View tools
• Counties, Communities, Parks, Highways, State Roads, Local Roads by using PL/SQL
• Shape files are loaded in Geo Server data store and generated the WMS layers and Implemented SLDs with Open Geo standards for Line, Point, and Polygon Geometries using
• Filters, CQL filters and rules. Configured Tile Cache server to cache the static WMS layers.
• Map Styles are built using Geo-Styler plug-in with the Geo Server.

• geometry features within the application.
• Map. Map Builder and Map Viewer are used from OC4J to configure the Map to view various
• Integrated Spatial Component Admin Tool with Digital video logger to view the Geometry features in
• the Google Map API for the project tracking purposes.
• Extensively used OC4J, Map Builder, and Map Viewer to design and generate maps within the
• application. Images data for the segments is stored in the form xml files and Oracle.
• The highway images and mile points data is integrated with Google map API with Google street map view to have the compatibility with current geographical data.
• Used JIRA portal to maintain source and track the activities of the team members.
