Electrical & Computer Engineering and Computer Science student at Duke University, graduating December 2027. I enjoy building and understanding complex technical systems, from software and algorithms to digital hardware and physical devices.

My interests are strongest in systems, embedded software, computer architecture, and hardware-software integration, but I am also excited by broader software engineering problems involving algorithms, performance, infrastructure, and large-scale systems. I am always looking to learn new technologies, work in unfamiliar domains, and take on problems that push me beyond what I have worked on before.

I am currently seeking Summer 2027 internships across software engineering, 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.
