CONSUMER HARDWARE IS EASY

ABOUT THIS BLOG

MY AI-NATIVE PLAYBOOK: Consumer tech to market — before raising a dollar.

I'm Jean. I make playful connected devices.

Serial entrepreneur, PhD in computer science, and coding software since age 12. I love to build and grow consumer tech products that brighten people's life.

Ten years of full-stack consumer-hardware operating experience — embedded/mobile software, supply chain, retail, digital marketing — through many cycles of growth, failure, and rebuild.

Some numbers. 300,000+ connected devices shipped across 40+ countries, $30M+ cumulative revenue. Two successful crowdfunding campaigns on Kickstarter and Wefunder, raising over $700K.

This blog is where I write everything down — the prompts, the decisions, the bits I think might be useful to other consumer tech creators trying to do the same.

How I shipped this blog in a couple of hours using Claude Code — Astro, Keystatic, Cloudflare for free.
The stack, the prompts that mattered, and how I actually work with Claude Code — directing rather than coding.

Iterating on hardware design with Nano Banana — before the mechanical engineer touches CAD.
Concept renders, material studies, form variations. How AI image generation collapses the gap between a rough idea and a brief your engineer can actually quote on.

Turning a shady NFC chip datasheet into a working iOS and Android module — with Claude Code reading the spec.
Half-translated PDFs, ambiguous protocol diagrams, vendor sample code that doesn't compile. How I get from there to a clean native module that ships.

Writing a spec for a PCB engineer with Claude Code — the template that saves rounds of back-and-forth.
What to include, what to leave to the engineer, what to lock down before fabrication. The reference doc I wish I'd had on the first project.

Designing product packaging with Claude Code and Nano Banana — without a packaging studio.
Box artwork, inserts, regulatory marks, print-ready files. The prompts, the print specs, the bits I still verify by hand.
