John Patterson | Ravenwood Tech Technical Founder
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.
iOS (SwiftUI, 15 frameworks), Python (Flask, SQLite, browser automation), Node.js, Chrome Extensions - designed and shipped across every layer.
Self-hosted LLM inference, Claude API integration, dynamic skill routing, vision-based form analysis - AI as the engine, not an add-on.
4+ years designing training for healthcare professionals and accountants. Film degree. I make complex technical systems accessible.
Four products across iOS, macOS, and Python - all designed, architected, and shipped solo.
