Hey! 👋 I’m Perry, a machine learning engineer with 7+ years of experience leading data and machine learning initiatives in early-stage companies. I helped start Fishtail, a trade finance automation platform where we use untraditional supply chain data to de-risk global trade and automate back-office processes. A few systems I’ve built at Fishtail include a document processing pipeline to extract structured data from unstructured documents, a reconciliation engine to automate trade finance repayments, and a daily global maritime port health index to de-risk global trade. I previously led data science at Farm Dog (acquired by Deveron), an agriculture tech startup building in-field tools to support agronomists.

Industry/Research Experience

• Co-founder and ML engineer at Fishtail where I’ve built tools such as a document processing pipeline, reconciliation engine, and port health index to automate and de-risk aspects of global trade finance.
• Data Science Lead at Farm Dog where I developed data pipelines and in-field tools to support agronomists with pest and disease data.
• Data Engineer @ Medical Tech Company where I built a Python package to generate highly customizable synthetic data to stress test in-hospital care software systems.
• Quant Analyst @ Crypto Hedge Fund where I developed algorithmic trading strategies and monitored portfolio performance.
• Personal projects including:
  • Bird Scooter Nest Generator: A web application that optimizes charging and redistribution of Bird scooters using machine learning.
  • Reverse Engineering the Walk Score Algorithm: Reverse engineered the Walk Score algorithm to predict walkability for Seattle neighborhoods.
  • Hiking Recommendation System: Developed a personalized recommendation engine for hiking trails.

Contact

In my free time you can find me in the backcountry, snowboarding, hiking or exploring startup ideas with friends. Some domains I’m currently interested in are regenerative agriculture, wildfire mitigation, supply chain efficiency, and human health.
