Client:LibertyMutual - RTM
Description:This project is leverage the existing storage capability/capacity for capturing granular driving
data from the Right Track Mobile program. This project will require establishing a feed with The Floow
(vendor) in order to receive the granular data captured from the smart phone application.
Building and storing a library of granular data will enable deeper analysis for scoring customers
and understanding driving behaviors. The data is currently stored at a 30-second interval except
in the situation of events, in which case, data is stored at a second-by-second level.
In order to conduct more advanced analysis such as analyzing a driver’s speed relative to the
speed limit, we will need to collect data at a second-by-second grain with latitude and longitude
readings. Storing data at a second-by-second grain will allow us to analyze driving behaviors in
certain weather conditions and at various times of day.

AOL(American Online)
Jan 2008 – July 2010, Senior Test Analyst
Project : Mobile Messaging.
Technologies : Linux, Perl, Python, SMS servers, Mobile Networks.
Description :
SAFE:
SAFE (SMS AFE) Supports AIM for SMS, IM2Cell, IM2MMS and AOL Single Short Code
applications.
SAFE is the application logic must parse the SMS message and use its destination address to
deduce the command and to formulate the request to WUDI. The application logic is the layer to
translate user commands into WUDI requests and process WUDI responses and events for the
user.
All SMS messages sent from users to AIM are routed via carriers’ SMSC. STUD will pack the
SMS messages and pass them to SAFE in the form of SNAC via QMI. SAFE unpacks the
SNAC and derives the SWIM+ commands from the SMS message’s destination addresses.
 It mainly involves delivery of SMS & MMS between mobile handsets and
desktops.
YAFE :
YAFE is mobile client proxy server handling translation of the Wireless Village protocol as
specified by the Open Mobile Alliance (OMA).It support Autowake,LBS,IMT features.
The AFE(Application Format Engine) which supports “Wireless Village” clients
Wireless Village is a set of specifications for mobile instant messaging and presence services
(IMPS). It is intended to be a standard for cell phones and mobile devices to use these services
across platforms.
Instant messaging (IM) is a form of real-time communication between two or more people based
on typed text. The text is conveyed via devices connected over a network such as the Internet.
Presence information is a status indicator that conveys ability and willingness of a potential
communication partner.
Many wireless phones now include mobile instant messaging capabilities designed to hook into
messaging services using IMPS on a carrier's network, formerly known as the Wireless Village
protocol.
Wireless Village protocol uses XML to represent the protocol data being exchanged during an
IMPS session.
