PROFESSIONAL EXPERIENCE

Confidential, Atlanta

Technical Associate and Lead Engineer

Responsibilities:

• Designed and implemented Page Handler component in teh HNBGW to handle teh RANAP PAGING messages from teh core network.
• Implemented Sigtran Router component to establish teh connectivity to Core Network. Involves protocols such as SCCP and M3UA.
• Implemented IuFlex feature which halps HNBGW to connect to multiple core networks.
• Played feature lead role for dis project, where in my responsibilities includes leading teh module, design, implementation, unit & integration testing and delivering teh product to system test team.
• Making use of agile model for developing teh feature, where in attending daily and weekly scrum meetings to track teh progress of teh development.
• Developed teh sequence diagrams using teh Enterprise Architecture.
• Writing unit tests using Google Test and Subsystem Integration test cases up to date match wif code daily basis to track teh progress of development, also useful in identifying any loop holes in teh implementation.
• Following teh strict instructions while reviewing teh code prepared by other team members and fixing / suggesting any better approaches in teh implementation.
• Supporting enhancement face of teh feature when it is in system test / customer lab
• Brainstorming/mentoring new team members by KT and code / product familiarization.

Senior Developer and Scrum Master

Responsibilities:

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

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

Feature Manager

Responsibilities:

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