- Currently handling the presilicon Validations of Upcoming Premium Mobile target and its reduced version targets. And Supporting the Stability on Snapdragon 8 Elite gen 5 (Samsung variant) issues.
- I have integrated the DCC registers script in our internal tool which helps to analyze the sleep related issues without depending on the other tech teams.
- I have written script to analyse the crash reason and all the similar issues to tag to it ,which helped in tackling more than 1000's of issues reported on the premium Snapdragon chipsets .
- I have written script to generate report which gives progress of the issues reported on the target with detailed information.
- I did presilicon and bringup of Snapdragon 8 Elite Gen 5 chipset Moblie platform and traiged and debugged the stability issues on the platform and had communicated across all tech teams to resolve the issues and provided the support from start to end.
- I have written the script to analyse and debug the complex issues which resulted in WDOG bites for Sensor Domain and integrated in the debug tool which helped in triaging and closing the issues efficiently.
- I did presilicon and bringup of Sanpdragon 8 Elite chipset Moblie platform and traiged and debugged the stability issues on the platform and had communicated across all tech teams to resolve the issues and provided the support from start to end.
- I did presilicon and bringup of Snapdragon XR2 Gen2 platform and traiged and debugged the stability issues on the platform and provided the support from start to end.
- I have written the script for SSR automation which used to automate the process of triggering the crashes and collecting the dumps.
- I have experience in minidump framework of Qualcomm chipset.I have developed QDI framework to remove memory sections of particular Audio,Sensor,Charger domains of Snapdragon processor. And also made necessary changes in our internal debug tool which helps to parse the minidump using cmm scripting.

Development Kit which includes tasks like module integration in to
the framework, Library creation, Simulation Tests and Development
of the Topology and Deployment of firmware on to the Board(Intel
NUC compute Element). - I have optimized Noise suppression and Echo cancellation algorithm
on Cadence HIFI 3 DSP and also have integrated the optimized DSP
algorithms from NatureDSP library in to our algorithms. - I have experience in Audio Algorithm integration in CAPI module to
Deployment of library on the Qualcomm HDK8250 board. I have
experience in Integration of Audio algorithms in the ELITE/CAPI
framework of Qualcomm Hexagon DSP and also had optimized the
Echo cancellation algorithm for Hexagon DSP using the SIMD
intrinsics. - I have optimized the Noise suppression algorithm for Intel core
Processors using Intel@AVX,. Intel@SVML, Intel@FMA SIMD
technologies , also developed a code snippet which can run the
individual optimized code that are supported by different Intel
Processors. - I have developed Profiling algorithm for Optimized code on Intel
Processors to measure the time it is taking across all the Intel
Processors for Windows as well as Linux Operating systems and
also developed automated testing script to test the code across all
the Intel Processors . - I have optimized the Audio algorithm for Knowles DeltaMax Core
DSP and also integrated the algorithm in to the ROME Audio
framework of the Knowles. - I have experience in programming the SIMD and VLIW architectures
with Debugging, Testing and Profiling skills. - I have experience in working with Fixed and Floating point
algorithms and also have worked with the Fixed and floating point
DSP's. - I also have experience in Developing ,Testing ,Debugging and
Profiling of Audio/Voice algorithms and also have experience in
building and flashing the Images on to the hardware boards. - I also have experience in writing scripts/test wrappers for testing
the API's using C and C++ programming language.
