Developed and customized embedded Linux builds and Board Support Packages (BSPs) for wearable devices.

Designed and debugged Linux device drivers to enable reliable hardware–software interaction.

Supported system bring-up, kernel-level customization, and platform integration for embedded products.

Designed and debugged system-level audio pipelines for concurrent playback and microphone capture.

Developed low-level positioning and sensor-related software for real-time wearable applications.

Worked in multi-OS environments involving Linux- and Android-based platforms to manage hardware controls and system functionality.

Built system-level communication components to support low-latency data exchange between software components.

Integrated and supported anti-rollback secure boot features, including firmware authenticity and integrity verification during system startup.

Worked with Python, tcl, and cmm scripting languages for mimicking systems, automation, integration, and regression testing

Testing involved working with the Wireless Communication Systems such as Bluetooth, UWB, FM, WLAN, & IEEE 802.15.4

Proficiently handled synchronization mechanisms, including interrupts, semaphores/mutexes, deadlock detection/prevention to ensure robust and concurrent code execution with multiple technologies like Bluetooth, LTE and Ultra-Wide Band (UWB)

Worked with the Wireless Communication Systems modules like the Radio, Baseband Hardware, & Protocol Stack Software

Defined, developed, & implemented test system hardware and software to support manual and automated test case scenario

Worked with the standard lab equipment including Oscilloscope, Logic Analyzer, Protocol analysers, and RF test equipment

Day to day activities included testing Wireless Connectivity HW IP and lower layer controller FW in Pre – Silicon emulation(on FPGA) & Post – Silicon validation environment, system bring-up, integration, optimization, & characterization of system

Worked closely with the design engineers to perform Root Cause Analysis, interpreting wireless specifications & the product requirements, organizing test results, compiling, & presenting test reports, and logging defects into the defects tracking system

Switching between multiple teams and multiple projects working as the lead engineer

Converting product features, concepts into prototypes to test feasibility of the possible product

Working with microcontrollers like STM32xx, TI MSP430xx, and Nordic nRF52xx

Working with RF technologies like Bluetooth Low Energy & RFID for prototyping

Testing, debugging, monitoring & documenting changes for design updates

Participating in design reviews. Supporting productionization plans with international, internal & external suppliers

Engaging with Mechanical & Industrial engineers to contribute to product specifications & designs

PLEASE NOTE: My position is Sr. Electrical Engineer but, I worked on Embedded systems. My time allotted to coding is more than 90-95% and the rest includes talking with Vendors, Suppliers or any place where the team needs technical support. It is a small team and have to wear multiple hats as needed.
