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.

Hi, I'm Erin

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

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

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.

What I Build

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.

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.

Experience

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

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

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

I work with a small number of teams each year on high-leverage problems in AI and spatial computing — where the product direction isn’t obvious and the decisions matter.

The work focuses on defining the system — how AI operates inside real products, workflows, and environments, not just models or prototypes.

This includes:

– Technical and business strategy for AI-native applications and spatial computing/XR hardware

– Building interfaces and workflows for spatial computing/XR and next-generation platforms

Advisory is selective and reserved for teams where I can have outsized impact.

Schedule an Advisory Session

Speaking

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

Most talks on AI and spatial computing stay at a surface level — without the technical depth, historical context, or understanding of real system constraints.

Mine focus on what actually works — how these systems get built, shipped, and used in practice.

Talks are grounded in real systems, drawing from work across AI, spatial computing/XR, web3, and product infrastructure.

Formats include:

– Keynotes

– Executive briefings

– Product and engineering deep dives
