OLCSC

OLCSC is Web Based Application for Houston Toll Roads. This application is being developed for the Toll road

Authority. The application would allow the public to set up EZTags through the web instead of having to go to the

EZTag store. The System provides functionalities such as ability to open an account online, add vehicles, pay

bills, update account information, and get EZtags mailed to the specified address.

This application is based on three tier MVC architecture. The business logic was developed using Struts

framework on the OC4J application server and JDeveloper as IDE as the Application server is built into it. JSTL

tags were extensively used for rendering the presentation functionality. Tiles framework was used for layout as

well as reuse the page definitions. Web-Services were created to interact with the backend.

Responsibilities:

• Designed and built system using J2EE, Struts and MVC

• Responsible for generating build script using Ant that compiles the code, precompiled the JSP, builds an

ear file and deployed on the application server

• Involved in setting up the entire environment for the developers.

• Responsible for development of UI using Struts components like Taglib, Tiles, JSTL, JSP,

JavaScript and HTML

• Responsible for setting up the tiles-framework

• Wrote delegates which had some of the back-end business logic and also calls to the web-service

• Involved in writing Filters for the application

• Wrote extensive validations by using the validation-framework

• Extensive JavaScript’s were also done

Eagle Transition Phase II

Eagle Inc. is an energy provider to Air Liquide. Air Liquide is required to pay for the energy it has consumed for

its various processes net of energy generated from its by-products which it sells to Eagle. Due to the large volume

of data generated, spreadsheets were not sufficient to hold all of the data. An ESP database was created to store

and analyze data.

Responsibilities:

• Analyzed several spreadsheets to read data.

• Worked on formulas to come up with values for many columns of the table

• Designed database schema from given spreadsheets.

• Worked with StarUML software to create a sketch of the database.

Quest Communication Inc., Columbus, OH March 05 – Feb 06

Java Developer and Database Analyst

LIMS/IPOD

LIMS is an IP resource management system consisting of Single User Interface (web based application providing

service information for Quest Data products), Logical inventory management system (LIMS), and Internet

Protocol Management System (iPAM). The Single User Interface (SUI) is not a database by itself but provides a

single view of data residing in multiple Quest systems. IPAM and LIMS are working components of SUI.

LIMS supports tracking of inventory elements in both provisioning of Quest services and post-visioning activities

such as trouble shooting and capacity planning.

While LIMS is an application with a front end GUI, IPOD is the background process/data mover serving as an

interface between LIMS and other disparate back office systems. IPAM is the Qwest Enterprise IP Address

Management System.

The business logic has been developed using EJB component framework on Weblogic Application Server. The

database was Oracle 9.1.

Responsibilities:

• Designed and implemented IPOD/LIMS system using MVC architecture and J2EE framework.

• Used Castor XML’s for “marshalling” and “unmarshalling” purposes.

• Developed Stateful Session Beans to implement business logic related to NVPN orders.

• Designed and developed Data Objects to store information such as port details, location

configuration etc.

• Created IPHelper Classes to validate IP addresses.

• Created Web Service to invoke NVPN Session Beans

• Designed JSP pages as a part to Single User Interface component (SUI) to display data

from multiple Quest systems.

• Developed Controller Beans to direct search pages to appropriate Session Beans.

• Optimized SQL queries to reduce search time for Quest product details from LIMS database.

NODE DATA

Node Data is a project which required querying three databases namely, F&E, TBS and LIMS containing

hardware information such as equipment details, circuit information and customer data. The databases had to be

queried and the results were stored in LIMS. The process was run each night to collect data and transfer

information to LIMS.

Responsibilities:

• Designed SQL’s to gather scattered hardware information from active circuits in various

• databases.

• Optimized above SQL’s to reduce runtime from 17 hours to less than 3 hours.

• Implemented Multi-Threading in-order to reduce runtime of the SQL’s.

• Designed Queries to get router information from higher order circuits.

• Designed SQL’s to update or insert hardware information.
