Hey, I’m Perry, an AI and data engineer who loves working with great people to leverage data and software to solve meaningful problems. I currently lead AI engineering at Digital Iron, building intelligent systems and data infrastructure to power aftersales and the upkeep of heavy machinery using service data.

Before that, 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.

Now

I live in Missoula, Montana. 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

Experience
