About Me
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

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.”
