The
Person

Ethan Cooley

Ethan Cooley is a Senior Machine Learning Engineer based in Charlotte, NC, building AI systems that improve how clinicians make decisions. He studied engineering and computer science at Wake Forest University and is currently pursuing a Master's in AI at Duke University's Pratt School of Engineering.

Outside of work he can be found running ultras in the mountains, competing in triathlons, skiing backcountry, or shredding trails on his mountain bike. He's a brother, a son, and a friend — the people in his life matter more than any finish line or job title.

Featured
Work

Trace Personal Project

2025  ·  React, Node.js, Vercel

  • Built a full-stack activity intelligence dashboard connecting to the Strava API — aggregating training history across runs, rides, and swims into a clean, filterable interface with summary statistics.
  • Engineered a secure OAuth 2.0 token exchange flow via a Node.js serverless backend, with automatic token refresh handling so sessions stay alive without re-authentication.
  • Rendered GPS route traces as pure canvas visualizations — no base maps, just the raw polyline — with layered glow effects and an animated card-to-fullscreen transition driven by live screen coordinates.
  • Surfaced sport-specific performance metrics per activity including pace, power, normalized power, heart rate, elevation gain, cadence, and suffer score.
ML Classification of Appendiceal Cancer Team Manager — Senior Capstone

Wake Forest University  ·  Aug 2020 — May 2021

  • Researched and developed ML models to process and classify histopathological images of appendiceal cancer — a rare, frequently misdiagnosed disease.
  • Built an object detection model using Faster-RCNN with Inception-ResNet-v2 to detect cancerous signet ring cells within histopathological images.
  • Developed a deep CNN using TensorFlow/Keras to classify appendiceal cancer subtypes with 85% accuracy vs. avg. pathologist accuracy of 52%.
  • Delivered a Flask/Python web app to Wake Forest Baptist Hospital doctors and pathologists for real-time image upload and model prediction.
