Embedded firmware
Bare-metal and RTOS firmware in C and C++ on STM32, ESP32, and MSP430. Drivers, interrupt-driven I/O, low-power modes, and bootloaders.

Open to work
I graduated from NC State in 2026 with a B.S. in Electrical and Computer Engineering, and I am looking for my first full-time engineering role. I want to join a team that puts real hardware in the field: embedded systems, hardware design, or test and validation. I am based in Raleigh, North Carolina, willing to relocate, and available to start immediately.
Why I fitSenior Design
- Role
- Hardware lead, firmware
- Stack
- STM32L4, LoRa, 4-layer PCB, FreeRTOS
- Result
- Three working nodes and a test report, on schedule
Core competencies
PCB design
Schematic capture and layout in KiCad, two to four layers. Stackup, impedance control, power integrity, DFM checks, and hand assembly down to 0402.
Digital and FPGA design
Verilog and SystemVerilog on Xilinx 7-series. Pipelined datapaths, AXI peripherals, timing closure in Vivado, and simulation with testbenches.
Signals and control
Sampling, filtering, and FFT analysis in MATLAB and Python. PID loops tuned on real plants, not just in simulation.
Test and validation
Oscilloscopes, logic analyzers, spectrum analyzers, and SCPI automation in Python. Every board ships with a test plan and measured results.
Power electronics
Linear and switching regulators, battery charging, and protection circuits. Thermal budgets checked with a thermocouple, not a guess.
How I work
Hands-onNot hands-off
I would rather probe a board than argue over a block diagram. Every project on this page ran on hardware I designed, assembled, and debugged myself.
LearnsAt speed
Senior design put KiCad, LoRa, and FreeRTOS in front of me in the same semester. I shipped with all three. New stacks are a week of reading, not a blocker.
TestedOn the bench
Simulation is where a design starts, not where it ends. I bring measured numbers to every review: efficiency curves, noise floors, timing margins.

Roles I'm targeting
Firmware on resource-constrained microcontrollers: drivers, RTOS tasks, power management, and the bring-up work between a bare board and a product. I have done this on three custom boards and would do it again on yours.
WherePreparationMeetsOpportunity
Four years in the labs at NC State, surrounded by the Research Triangle's hardware companies. The coursework is done. The next board I bring up should be yours.
