I'm Erin Jerri.

Creating the systems that shape reality.

Author of the first O’Reilly book in AI + spatial computing in over 5 years.

Founder & former CTO. Engineer. Systems builder.

I build AI and spatial computing systems — one experience at a time.

I’ve been shipping in AI, AR, and web3 since 2015.

I’m the lead author of one of the first comprehensive AR/VR books published by O’Reilly Media in over five years — helping define how engineering, design, and business come together in real systems.

I’m a software engineer, startup founder, and former CTO.

I focus on what happens after the model - when AI has to operate inside products, workflows, and environments.

When AI has to operate inside products, workflows, and environments.

AI Agents

Systems that operate beyond chat - executing inside real products and workflows.

Spatial Computing

AR, VR, and mixed reality interfaces built for visionOS, iOS, and what comes next.

Product Systems

Architecture and strategy for AI-native products designed to scale in the real world.

My work spans AI, spatial computing, and product systems built for real-world use — across iOS, visionOS, and emerging interfaces.

I focus on what happens after the model — when AI has to operate inside products, workflows, and environments.

Experience

Selected for programs and fellowships across AI, XR, and web3, including AWS CTO Fellowship, Alley (Verizon Ventures), and Gitcoin Kernel.

Buy Books in English, Chinese, and Korean

The book is distributed in 42+ countries and translated in multiple languages.

I build systems where AI moves beyond chat — and into execution.

– AI agents operating inside applications

– Spatial computing interfaces (AR/VR/MR)

– Product systems designed for real-world workflows

My work focuses on turning intelligence into something that acts — not just responds.

TimeBite is an AI + spatial computing system for how you actually spend your time.

It’s what I’m building right now — a LifeOS for how people make decisions, spend time, and operate day to day.

Most tools are built around planning. But that’s not how things actually play out. TimeBite makes that visible — how your days actually unfold, not just what you intended

Work with Me

I work with founders and teams building at the edge of AI, spatial computing/XR, and web3 at points where direction, positioning, and growth start to matter more.

The focus is on sharpening the product — what it is, how it differentiates, and how it holds up as it scales.

My background spans AI, spatial computing/XR, web3 across as well as building technology for film and media.

Speaking

Erin speaks at conferences, company events, and technical summits on AI, spatial computing, and how these systems are applied in real products and workflows.

Talks are grounded in real-world systems — not only where the technology is going, but how it’s actually being used.

Engagements are selective, with a focus on technical and executive audiences.

Hi, I’m Erin! 👋🏼

I’m a software engineer, startup founder, and writer, born and raised in Silicon Valley.

I’ve been building in AI, spatial computing, and web3 since 2015.

I'm widely known as the lead author and co-editor of O’Reilly Media's Creating Augmented and Virtual Realities: Theory and Practice for Next-Generation Spatial Computing, which debuted #1 in Amazon’s Game Programming category and has been translated into Chinese and Korean, reaching readers around the world.

I'm a proud UC Berkeley alumnus and was previously a fast.ai deep learning fellow through the University of San Francisco’s Deep Learning program (2017-2018) and Data Ethics inaugural class (2020).

Right now, I’m building TimeBite — along with new books, apps, and film projects.
