Confidential

Sr. Software Engineer

Responsibilities:

• Involved in design and development of SRNS Relocation feature where the role of the serving Confidential for a UE is moved from one Confidential to another. As a result, the IU connection between the CN and the Confidential is moved from the old SRNC to new SRNC. SRNC Relocation normally occurs when the UE moves out of the area serviced by the old SRNC to a region serviced by another Confidential .
• Designed and implemented RRC Re-establishment feature which enables Confidential to re-establish the RRC connection due to Cell Update with Radio Link Failure or RLC Unrecoverable error. This feature helps in decreasing the call drop rate.
• Enhanced the Always-On feature which helps Confidential in efficiently utilizing the Radio Resources based on Traffic Volume measurements.
• Followed agile scrum methodology, wherein attended daily standup meetings to track the sprint work assigned on weekly basis.
• Strictly reviewing the code done by other team members and performing unit / integration testing as per the test cases created and delivering the code to client.

Environment: C++, ClearCase, Rational Purify, Rational Rose, Wireshark

Confidential

Software Engineer/Feature Manager

Responsibilities:

• Designed and implemented Binary SIP feature in PoC Server, which helps to decrease the initial call setup time. This was achieved by sending the INVITE message over the access channel along with other messages sent while requesting to acquire the traffic channel.
• Designed and implemented Delayed ACK feature, which helps to decrease push-to-hear latency.
• Strictly reviewing the code done by other team members and performing unit / integration testing as per the test cases created and delivering the code to client.
• Supporting integration and QA testing phases as well as production to analyze the root cause and fix if there any issues comes in.
