Open to Opportunities

I build AI-powered products people actually use.

Technical founder who designed, architected, and shipped four products - an iOS AI assistant, a 36,000-line macOS AI operating system, a health-tech app, and a full-stack automation platform. Looking for Developer Relations and Technical PM roles.

John Patterson | Ravenwood Tech Technical Founder

Technical founder. Product thinker. Builder.

I'm John Patterson, founder of Ravenwood Tech LLC in Portland, OR. I design and ship AI-powered products across iOS, macOS, and Python - from concept through App Store submission. I've integrated 15 Apple frameworks, 13 messaging platforms, 4-layer cognitive memory, and self-hosted LLM inference into production applications, all as a solo founder.

My background in instructional design and multimedia production means I don't just build things that work - I build things people can actually understand and use. I've spent 4+ years translating complex systems into accessible experiences, first for healthcare and compliance training, now for consumer AI products.

I applied to Y Combinator. I'm looking for Developer Relations or Technical PM roles at AI-forward companies where I can combine deep product architecture knowledge with my instinct for teaching and community.
