About

Content strategist. Tool builder.

I write about complex technology for business audiences and build tools for people who read and write.

Professional background

15+ years planning, writing, and managing thought leadership and promotional content for B2B tech companies including Adobe, ChargePoint, Confluent, HP, Magento, and VidMob. As Director of Content Strategy and Services at The Argonaut, I grew content services revenue from $400K to $1.5M and produced 250+ content assets annually for Fortune 500 clients.

I managed freelancers and led cross-functional teams including strategists, PMs, and graphic designers. I specialize in translating complex technical concepts into useful, informative content for business and technical audiences.

A multi-talented force: expert writer, sharp strategist, and skilled project manager. Her keen grasp of complex concepts—and how to transform them into effective content—made her an invaluable collaborator.

Why I build tools

During the pandemic, I learned SwiftUI to build tablet apps for my kids. When AI coding assistants launched, I wondered if they could actually help me code, so I experimented, learning Python and JavaScript along the way.

I discovered that AI could help me build tools to support research, writing, and content workflows. Since then, I've been building tools and sharing them through my Substack newsletter.
