Personal project · PCB design
An STM32F405 flight controller for a 4S FPV quad, running Betaflight on a target I wrote (ETHANF405). The gyro gets its own LDO so logic noise stays off its rail, and a TPS5450 buck makes 5 V straight from the pack. Solder jumpers split the power tree, so I could bring the board up one stage at a time.

Class project · Microcontrollers
A door lock that asks for two things: a 4-digit code on a keypad, then a password over UART. Bare-metal C on an ATmega328PB, with Timer1 PWM driving the servo.

Class capstone · Digital design
A 0 to 1000 up/down counter in VHDL on a Basys3. The debouncer, counter, BCD converter and 7‑segment driver each got their own testbench before I wired them together. The whole thing fits in 117 of the Artix-7's 20,800 slices.

Class project · Integrated circuits
A CMOS cell library in Tanner EDA on a 250 nm process. It started with a hand-drawn inverter and ended with a 2-bit parallel adder in a pad frame, all checked with DRC and LVS.

Competition build · Autonomous robots
Won first place. I wrote the C firmware for a robot that read QR codes to pick a cube color, collected those cubes from a 4×6 ft arena, and found its way home by the brightness of the floor.
