I have more than 7 Years of
Total IT experience in Mobile handsets and data card testing which requires
the technology in depth understanding of LTE, eHRPD, IMS and canonic
understanding of UMTS, EV-DO, CDMA and GPS.
Adept in understanding the
requirement, creating test cases on basis of use cases. Hotshot in testing
the feature, creating CRs, and enhancing the coverage on basis of
traceability matrix, and excellent issue verification and debugging skill.

Mobile View Application
Duration
:
Aug 2006 to May
2007
Work
Location: TCS Gurgaon
Description:
The MobileView™ UM is a application
that allows you to configure data collection, data uploading, and MobileView
application parameters for a set of BREW™-enabled handsets running the
MobileView applications. The User Manager acts as an interface between the
user and MobileView server. The UM is used to store logs of failure events
such as call drops, access failure, idle failure etc. from the handset. The
data collected can then be processed to generate statistical reports on the
types of failures and maps to locate the location of occurrences of each of
these failure events. The User is given access to these data and reports via
the User Manager, which can be operated through the
internet.
Responsibilities
and Testing performed:
1. Development & Execution of Test
Cases for Mobile View User Manager.
2. Collection and Verification of
field logs.
3. Server API testing
4. Performance Testing
