PROFESSIONAL EXPERIENCE

Confidential, Irving, TX

Area Feature Owner, System Level Design Engineer, Development Engineer

Responsibilities:

• Worked in roles corresponding to System level Design, Development, Unit test and Module test for developing features related to Outer loop power control (OLPC) in L2 layer of UMTS protocol stack.
• Enhanced the legacy OLPC functionality of Confidential with Confidential proprietary algorithms working with the system architects for better power control.
• Enhanced the design of the OLPC subsystem using Microsoft Visio to in corporate the new algorithms. Implemented the changes required using C programming.
• Written new unit level test cases using CppUnit and module level test cases using TTCN programming and executed them to validate the new algorithms.
• Redesigned the debug support for OLPC subsystem in Confidential and created the flow charts using Microsoft Visio.
• Implemented the changes using C programming. Validated the changes using unit test and analyzing the system level test logs.
• Enhanced the framework to generate the interface message templates required for decoding the interface messages to human readable format in a proprietary message viewing tool Emil using Python, for log analysis.
• Worked to execute Proof of Concept (POC) utilizing C programming to test the proposed Confidential proprietary algorithms for enhancing the OLPC functionality.
• Involved in knowledge building exercises in Hadoop and Big data technologies with an aim to understand the new technologies and their applicability.
• Worked on identifying and implementing the changes required for the OLPC subsystem of the Confidential software to enable running it on the Confidential telco cloud solution Airframe as part of the trial implementation.
• Worked on adapting the existing OLPC module level test cases to work with the cloud enabled Confidential software.
• Used the Airframe cloud manager to create cloud instances and testing the software changes in a sub-system level test environment.
• Lead a team of 6 engineers through agile methodology of the development for the feature Enhanced power control in Confidential .
• Co-ordinated with multiple stakeholders starting from System level architects to development and various levels of test teams to drive the feature development from technical side.
• Raised many issues during the reviews of multiple artifacts such as Requirements, Design, Code, Test plan, Configurations and Interfaces which helped in reducing the defects in later phases and to reduce the cost of effort.
• Have been working as first point of contact for all queries and issues in the Power Control area, from all the different levels of testing including pilot testing with customers.
• Have been working closely with test teams from multiple test levels and proposed changes to functionality based on the behavior of the system along with system architects. Also, guided the development team towards implementing those solutions.
• Have been resolving issues reported from field and multiple test levels by providing solutions to the bugs identified through in-depth analysis.
