Hey! I’m Perry - a data scientist and machine learning engineer with 8+ years of experience building data-driven systems and leading ML initiatives in early-stage companies. I co-founded Fishtail, a trade finance automation platform using alternative supply chain data and machine learning to streamline back-office ops and de-risk global trade. Previously led data science at Farm Dog (acquired by Deveron), where I built tools to help agronomists track pest and disease pressure in the field.

I’ve also worked on projects ranging from medical image segmentation, to building a stress testing library for hospital systems, to algorithmic trading across crypto markets.

Now

I currently live in Missoula, Montana. In my free time I love exploring remote wilderness areas by climbing, hiking, or snowboarding. Lately I’ve been interested in, researching and talking with folks in the following domains:

• Regenerative agriculture
• Wildfire mitigation
• Supply chain efficiency
• Human health optimization

Experience

• ML engineer and Co-founder at Fishtail
  • Built a document understanding engine to extract structured data from unstructured documents of any format
  • Developed a reconciliation engine to automate trade finance repayments
  • Created a global port health index to monitor risk across maritime supply chains
• Lead Data Scientist at Farm Dog
  • Built data pipelines and in-field tools to support agronomists with real-time pest and disease insights
• Project Work
  • Built a configurable Python library to stress test hospital software by simulating complex patient flows across dynamic hospital layouts
  • Collaborated with a leading radiologist to develop an image segmentation model for identifying colorectal patients and detecting lymphoma tumors using medical imagery
  • Optimized slow-performing SQL queries for an EV battery analytics platform, reducing execution times and enabling real-time cost analysis for charging
• Quant Analyst @ Strix Leviathan
  • Developed algorithmic trading strategies across a wide variety of cryptocurrency markets
  • Analyzed market data to identify trading opportunities and optimize portfolio performance

Personal Projects

• Bird Scooter Nest Generator: Built a web-app that uses ML to optimize charging and redistribution locations for Bird scooters.
• Reverse Engineering the Walk Score Algorithm: Identified key predictive features behind the Walk Score algorithm to model walkability in Seattle neighborhoods.
• Hiking Recommendation System: Created a personalized recommendation engine for hiking trails — think of it as a “Netflix for hikes.”
