01 / hello from the arizona valley
Hi, I'm Nicholas Leigh.
I'm a computer science student at Arizona State University. I've been sharpening my data structures and algorithms fundamentals in my LeetCode repository, building artificial intelligence and machine learning models, and going deep on AWS and the cloud. You can find all of it in my projects below.

Things I've built.
Cloud Collar
Employee productivity analytics built for privacy. YOLOv8 and ResNet18 run locally on a Raspberry Pi to track floor time and phone usage, forwarding only anonymized metrics to an AWS pipeline provisioned with Terraform.
python · terraform · aws · yolov8 · pytorch
NNFS
A neural network built from scratch in plain Python. Layers, activations, and backpropagation with no frameworks, so every moving part is understood.
python · numpy
nicksnexus
My personal portfolio website, dark glass floating over a live WebGL backdrop. But you’re already here!
typescript · astro · three.js
LeetCode
My DSA grind, tracked in public. Solutions organized by topic and difficulty, curated problem lists from my own picks to Blind 75 and NeetCode 250, syntax references, and learning notes all in one place.
