Core API, Database & Telemetry Pipeline

A Node/Express REST API on PostgreSQL. I designed the database schema behind fleets, vehicles, devices, routes and scheduling, and migrated it into the core database. On the team's Redis Streams sensor pipeline I built the main processor, which validates IMU (100 Hz), GPS (50 Hz) and camera events, writes them to TimescaleDB and uploads them to a remote server with retry.

Sumo Bot · GE Appliances

Built and programmed a sumo bot in C on an Adafruit Metro M0 with IR sensors, ultrasonic sensors, DC motors and LEDs. It placed 1st in the final competition.

Self-Aligning Wireless Power Transfer

A robot that finds an EV's receiver coil and moves the charging pad under it, reaching 1.53% misalignment in lab testing. Our senior design team is acknowledged in the IEEE Access paper on it (2024).

Pandas vs Cats & Dogs: CNN Image Classifiers

Neural Networks Project 2: built and iterated two convolutional image classifiers in TensorFlow/Keras over three model versions each. Best test accuracy on 200-image test sets: 0.97 for pandas vs dogs and 0.955 for pandas vs cats.

More coursework on my GitHub: an MLP digit classifier, an EKG heart-attack classifier, Perceptron/Adaline vowel classifiers, power-plant regression and phishing detection.
