Designed and implemented firmware (Embedded C) for the next-gen RISCV-based Chips focusing on the BLE and UWB technology as per proprietary standard specification for the host and controller layer. Responsible for testing (Pre-silicon and post-silicon), debugging, and fixing issues. Actively participated in code reviews, document software designs, and compliance with coding standards.

Teaching Assistant for ECEN 5823 Internet of Things Embedded Firmware course. Responsible for conducting labs for and helping students in debugging IoT projects and applications, resolving issues, and clearing doubts on the lectures. Also helping the professor in managing and updating course work. https://sites.google.com/colorado.edu/ecen5823-s2020/home

Ultra-wideband technology (802.15.4a/802.15.4z) and Designing POC including project planning, evaluating processors(nrf52840), and developing an application(Ranging on UWB) for evaluation of performance, throughput, encryption, and other embedded parameters. This project primarily includes skills in wireless technology, Embedded C, logic analyzers, and spectrum Analyzers. Followed procedures for testing modules in pre-silicon and post-silicon testing of modules and testing on FPGA servers. Understand Bluetooth Classic and Bluetooth Low Energy and debug BLE packets at radio layers with Ellisys Bluetooth Analyzer.

Major development of application to check performance for drivers, ISR, XML, API's etc. on various major platforms such as STM32, NXP and Renesas over RTOS and bare metal platforms achieving requirement of the project. software Expertise: e2studio, STMCubeMx, MCUExpreso

Bluetooth Low Energy: Development of Bluetooth profiles and services (Environment Sensing, Automotive input output etc.) as per Bluetooth specifications and writing unit test. Have worked on development of drivers and frameworks for development platform for Cortex M4 based Microcontrollers. Also includes implementing new features and writing integrated test.

Hands on training of Embedded Systems Design with the following subjects: • 8 Bit MCU • 32 Bit ARM MCU • Embedded C • Linux • C, C++ • Linux Device Drivers • Real Time Operating Systems Project: • Vehicle monitoring using CAN and IoT • Implemented Controller Area Network protocol with IoT, where Electronic Control Unit (ECU) driven through based on STM32F407 (ARM cortex M4) board. Black and STM32F4 microcontroller. • Parameters in vehicle are measured using sensors attached to the system and forward to Global Server (Internet) using MQTT protocol making it globally accessible. ECU via CAN bus.
