Hey, I’m Perry, a data scientist and engineer who loves working with great people to leverage data and software to solve meaningful problems. I’m experienced in building data pipelines, machine learning systems, custom ML evaluation tooling and data products. I co-founded Fishtail, a trade finance automation platform using supply chain data and data science to optimize back-office operations and de-risk global trade. I previously led data science at Farm Dog (acquired by Deveron), where I built data infrastructure and tools to help agronomists track pest and disease pressure in the field.

I’ve also worked on projects including segmenting medical images, building a stress-testing library for hospital systems, and developing algorithmic trading strategies across cryptocurrency markets.

Now

I currently live in Missoula, Montana. I’m a Lead AI Engineer at Digital Iron where we’re building a robust platform for AI-powered construction machinery maintenance and service support. In my free time you can find me hiking, climbing, snowboarding and exploring wilderness areas. I’ve recently been interested in and researching the following domains:

• Regenerative agriculture
• Wildfire mitigation
• Supply chain efficiency
• Preventive human healthcare
