• Designed and developed multiple SW features and functionalities on Netcomm's Fixed Wireless Access(FWA) suite of products that deliver wireless high performance connectivity solutions for urban, suburban, and rural environments.
• Played a lead role in the implementation & deployment of the Citizen Broadband Radio Service (CBRS) protocol on Netcomm's FWA products that were deployed in the NA region by tier-1 and tier-2 service providers.
• Liaised with multi disciplinary teams that included SW, HW, QA and Technical Account Management teams, in triaging and fixing complex issues blocking factory production and carrier target acceptance.
• Implemented SW workarounds and fixed critical issues that were encountered only on customer's test setup.
• Went above and beyond on on numerous occasions while working outside office hours with the Technical Account Management team in debugging critical issues found during deployment of the FWA products on customer's environment(NSW transport, Sydney waters sewage systems etc).
• Ran customer meetings in understanding the requirements, scoped the efforts for various feature requests, created JIRA tasks & sub-tasks and participated in status update calls with the customer.
• Mentored junior members in the team, presented code walkthroughs and ramped them up to speed with the existing and upcoming projects.

• Design and Development of Firmware features on ARM Cortex platform - implemented platform boot up sequence, developed in-band sleep low power mode protocol to reduce the WCN chip power consumption, designed an efficient memory allocation technique to avoid memory fragmentation, introduced Stack corruption detection mechanisms, designed Smart TV Wakeup features, fixed multiple firmware crashes using t32 ARM Simulator.
• Kernel development on Qualcomm MSM chipset -designed bring up sequence on multiple Qualcomm WCN chipsets, implemented low power mode drivers, developed Host-to-Controller interface(HCI) drivers for UART, USB and SMD based WCN chipsets, reduced audio latency on Smart TV by interfacing the Kernel Audio interface with user-space Stack, improved the performance of the system by utilizing the new kernel features in the driver design.

Collaborated with product and customer engineering team members to understand, define and develop the Wakeup on Bluetooth LE (WoBLE) feature. Successfully implemented and delivered the feature to the OEM within the stipulated timelines.

• Designed, developed and implemented multiple SW and Firmware features to support new product requirements from different OEMs on mobile, automotive infotainment and consumer electronics segments.
• Conducted technical workshops with customer facing teams to help them understand the product architecture and design.
• Followed pre-silicon process to write stubs and unit test cases to validate the functionalities before the actual tape out happens. This reduced the bring up time significantly and speed up the deliverable to OEMs
• Drove continual improvement to system architecture by refactoring old legacy code.
• Coordinated with QA testers for running end-to-end functional, concurrency and Stress and Stability tests to deliver high quality code to OEMs and customers.
• Interacted with multi-disciplinary teams across the globe in addressing complex system level issues.
• Travelled to OEM/customer development centres to fix bugs and offer technical assistance during product launch times.
• Designed & Developed HW Abstraction Layers and multi-threaded applications using PTHREAD library and C to suit OEM Framework & Application Layer
• Created detailed design objectives and developed architectural and system design documents of the various features

• Defined the FM Architecture on Android and implemented multiple FM Receiver functionalities -seek, search, tune, RDS features, did performance optimizations, reduced the power consumption of FM chipset, implemented alternate frequency (AF) jump algorithm, developed Spur rotation table to filter out spurious frequencies during search, reduced noise component and interference portion in the audio by using signal blending and soft mute features.
• Travelled to Sweden Sony Development Centre to resolve FM firmware issues and successfully integrated the FM HAL layer with 3rd party FM Framework and Application.

• Multimedia and Kernel development on VOIP domain -
  board bring up activity on Android Video Conferencing phone that used OMAP3530 platform, programmed the DSP Controller for encoding and decoding video packets using DVSDK framework, loaded codec server image onto DSP and instantiated H.264 encoder and decoder algorithms, used V4L2 camera framework to capture video streams from camera interface and routed it to DSP for encoding and decoding the data, developed multi-threaded application for video capture, encoder, decoder and display purposes, developed SPORT driver for transfer of Audio data to DSP and added DMA feature to the existing SPORT driver to enhance the speed in transferring audio packets from processor to DSP core, implemented a stand-alone program for loading DSP binary image onto the DSP core using the SPI interface available between the Black-fin processor and the DSP.
