EXPERIENCE:

Carey International, Washington DC Web Developer Nov 06 to present

eRes: This is an online reservation system for Limousine and other executive sedans or vans with chauffeured services provided by Carey International worldwide. Public users can book these services using their credit cards or their pre-approved organizational accounts setup with the Carey. There are two types of public users -one is passenger and other is arranger. Passenger is a public user who is going to arrange travel for him only. Arranger is one who is going to arrange travel for others. Users have to register to eRes for a reservation by creating their profile. The arranger can also save his customers (i.e. passengers for whom he is going to book) in his profile so that there is no need to enter the passenger details every time for a new booking.

Organizations can open accounts with Carey. Account will have some special discounts and people of that organization can use that account for their reservation to get that discount.

Also, Carey wanted to link eRes with AAA to get referrals from AAA and its franchises. Any referral from AAA will get some special discounts for reservation on Carey website. AAA will pass some parameters along with encoded timestamp to Carey eRes while referring a customer to Carey. Some of these parameters are encrypted and need to be decrypted before use. Before having AAA linking, Carey needs to be PCI-DSS (Payment Card Industry- Data Security Standard) compliant.

eRes uses Struts framework and JavaScript for presentation and uses J2EE web-services to get geographic data (country, city, airport etc.) and EJBs also for credit card validation etc. JCA (Java Cryptography Architecture) and JCE (Java Cryptography Extension) is used to implement the cryptography and keystore management in AAA linking and navigation.
Responsibilities:

Solely involved in creating architectural framework for the complete workflow for AAA linking.

Involved in High level Design and detailed design activity for PCI-DSS compliance.

Solely implemented the AAA linking with eRes including cryptography and keystore management.

Developed Proof of concept and provided work/time estimates for design and development efforts for PCI-DSS compliance which involved various cryptography related issues and authentication and authorization issues also.

Every user (partner) has to login through the GNSweb and the homepage of the GNSweb provide the personalized business information and links to the enrolled online services.

Admin flow uses Struts and tiles framework and AJAX for registering various partners and changing their entitlements to various services. A DB2 database is used to store the complete user profile. For integrating the various business services with GNSweb, EJBs are used.
