Electrical & Computer Engineering and Computer Science student at Duke University, graduating December 2027. I build low-level systems where software, digital hardware, and physical devices have to work together reliably.
I am currently seeking Summer 2027 internships in embedded software, firmware, systems, FPGA/RTL, computer architecture, and hardware-software integration.

Built a physical two-axis drawing machine around a custom five-stage, 32-bit pipelined MIPS processor on a Nexys A7 FPGA. The system combines Verilog RTL, forwarding and hazard control, MMIO, a Bresenham motion controller, MIPS firmware, and a Python image compiler.
Verilog FPGA Computer Architecture MIPS MMIO Vivado GTKWave Python
Led flight-computer firmware features and a PCB-based black-box redesign spanning embedded C++, sensor and radio interfaces, fault-aware state logic, KiCad, board bring-up, hardware-in-the-loop testing, and supercapacitor-backed data preservation during power loss.
Embedded C++ PCB Design KiCad I2C SPI UART LoRa Hardware-in-the-Loop
Built Linux/Python monitoring that preserves remote access to deployed IoT devices as router public IP addresses change, with an authenticated Flask API, durable SQLite history, retry logic, and automated tests.
