Electrical engineer and builder. Here are some things I’ve made.

Custom Drone Flight Controller PCB

Designed a custom 4-layer flight controller PCB around the STM32F405, covering IMU routing, ESC headers, power regulation, and DFM review.

Seven-Segment Gesture Lock

Built a gesture-based combination lock using an LIS3DH accelerometer over SPI, with a seven-segment display for feedback and a custom gesture recognition algorithm.

Soft Robotics Pneumatic Control

Implemented closed-loop pneumatic pressure control for a soft robotics gripper using a Teensy microcontroller, PID tuning, and a ROS 2 interface over CAN bus.

Project Pie (AI Career Navigation Tool)

Hackathon project: an AI-powered career navigation tool that maps skill gaps and suggests learning paths, built with a Flask backend and React frontend.

Comprankle (Wearable Ankle Rehabilitation Device)

Designed and built a wearable ankle rehabilitation device that tracks range-of-motion with an IMU and provides vibrotactile feedback to guide recovery exercises.
