Software Engineer

Responsibilities:

• Set up the lab for VPN tunnel establishment, configuring Cisco, Juniper and Nortel gateways and used multiple devices such as Routers, Switches, various models of Avaya VOIP phones.
• Implemented the phones to work in Virtual Private Network using Protocols IKE (for key exchange using Diffie-Hellman algorithm), IPSec to provide authentication and encryption of IP packets.
• Implemented packet traversing using protocols TCP/IP, UDP and transfer of file was done using protocol FTP.
• Message queues, shared memory, semaphores and mutex were used as inter process communication and synchronization mechanisms.
• Worked on the functional implementation of GUI of different screens of many models of Avaya VOIP Phones includes H323 press button and touch screen phones, which includes password protected start up screens, user authentication, tunnel failure screens, sleep mode, editing screens, contact, call log, WIB, SCEP interrupt and event record for certificate renewal attempts.
• Designed and developed GUI of the various screens using C and C++ in UNIX/Linux and Vxworks environment. Used C++ STL containers like Maps, Vectors and List to manage multi-access control from different user-interfaces.
• Used Singleton, Factory, Adapter and Observer design patterns in the development to provide extensive solutions.
• Debugging of applications using GNU, gdb and serial Debugger.
• Developed internal schedule, implementation and quality plan for the feature development in Agile Methodology.
• Prepared unit test, integration test plans and performed unit and integration testing for respective modules.
• Used UNIX Shell (BASH) Scripting and Python to write unit, integration and sanity test cases.
• Fixed the issues during System Verification and field issues, performed root cause analysis over core dump files using GNU gdb and fixed the issues. Resolved many memory leak issues.
• Experience with multisite source management using Clear Case Unified Chain Modeling (UCM). Knowledge of UCM VOBs, projects, integration streams, child streams. Experience with creation of snapshot and dynamic views.
• Once the project entered SV stage then responsible for fixing MRs reported by SV Team.
• Responsible for builds and release of the project to client.
• Client and Customer interaction for requirement gathering.
• Check the feasibility, dependencies of individual requirements.
• Adhering to quality guidelines by using quality tools WCC and Deep Check.
