I am an electronics and communication engineering undergraduate specializing in low-level firmware architecture, embedded Linux, and hardware design. My work spans the entire embedded stack—from bare-metal microcontroller programming and custom bootloaders to complex RTOS implementations, Linux kernel modules, and custom PCB design.

• Tools & Hardware: STM32CubeIDE, KiCad, GCC Toolchain, GDB, Logic Analyzers, Oscilloscopes, Electromechanical Relays

An advanced power electronics project delivering a programmable DC output negotiated via USB-C Power Delivery.

• Integrated the CH224K PD controller to dynamically negotiate voltages from 5V to 20V.
• Developed STM32 firmware to interface with an INA226 sensor over I2C for real-time telemetry on an OLED display.
• Designed a custom multi-layer PCB in KiCad featuring high-current power planes and PMOS-based reverse-current protection.

A comprehensive dive into the Linux device model on the AM335x (BeagleBone Black) architecture.

• Developed custom platform drivers and character device drivers for hardware interfacing.
• Engineered hardware abstraction via Device Tree Source (DTS) and cross-compiled the Linux Kernel and U-Boot from scratch.

A from-scratch bootloader implementation designed to manage host applications and flash memory architecture on ARM Cortex-M systems.

A fault-tolerant, STM32-based intelligent overspeed detection system.

• Engineered board support packages to interface GPS and GSM modules.
• Implemented an interrupt-driven firmware architecture for real-time monitoring and low-latency violation reporting.

A pure hardware logic project demonstrating digital switching theory.

• Architected complex combinational logic (Full Adders, SR Latches) using entirely electromechanical SPDT relays, without any semiconductor logic gates.

I have dedicated significant time to mastering core embedded concepts through rigorous, project-based coursework:

• Mastering RTOS (FreeRTOS): Implemented FreeRTOS task scheduling, synchronization primitives, and debugging via Segger SystemView.
• ARM Cortex-M DMA Programming: Explored direct memory access controller architecture and driver development to offload CPU tasks.
• Embedded System Design Using UML: Designed state charts and Finite State Machines using the Quantum Leaps Framework.
• Bare-Metal MCU Programming (Level 1 & 2): Authored peripheral drivers (SPI, I2C, UART, CAN, Timers, RTC) for the STM32F411CEU6 directly from datasheets.
