Design and Development for MME/C-SGN and Production Support for a major Telecom OEM(Aug 2012 - Sep 2017) - Design and Development of features as per standard telecom specifications (3GPP) in C++ for Evolved Packet Core network devices including MME and C-SGN. Analysing and fixing issues reported in lab testing. - Analysis of issues reported from field for a major Asian operator, and replicating the issues in lab, debugging and fixing the issues. - Achievements: Spot award for the performance on Production support teamVerification of functionality of network controlled by ONOS as part of virtualization of a service providers’ Modem Termination System; and automation of the verification (Oct 2017 - May 2018)Product Line Maintenance for B-RAS EDGE Routers (Sep 2010 - Jul 2012) - The project involved supporting of field issues reported by service providers for EDGE Routers of a major datacom OEM. The reported issues were analysed, categorized and reproduced based on requirement and passed on to the relevant development team.

Maintenance of Audio DSP code base for a major mobile phone manufacturer(Sep 2008 – Aug2010) - Bug-fixing and feature additions in C language on Audio DSP code base. - Responsible: Analyse the bugs with help of signals send between different processes, fixing the code and verification. - Achievements: Was member of the expert technical team that travelled to client location (in the UK, for 9 months). The performance of the team resulted in signing of long term association with the client. Optimization of MP3 decoder and AMRNB decoder for ARM11 (May2008 – Aug2008) - Identify critical modules on a MP3 decoder written in ARM9 assembly and rewrite those modules using ARM11 and do further optimization. Rewrite critical modules using ARM11 instruction set and optimize for AMRNB decoder. - Achievements: Target MIPS was attained before the scheduled time for MP3 decoder and so could support in AMRNB module, there by the total project could be finished before target date. Recognised by both client and company for the work Implementation of Audio Mixer (Jun2007 – Apr2008) - Design and implementation of an audio mixer capable of mixing up to 3 input streams (mono/stereo) of different sampling rate; in C, based on existing design document for a two stream mixer. Test case creation, Bug fixing and C level optimisation. Optimisation for the modules that were rewritten in ARM assembly.
