I'm Mike Charpin, an industrial designer who builds the whole thing: mechanical design, CAD, CNC-fabricated prototypes, and the software or e-commerce layer around it. I work with a small number of startups at a time, not an agency, not a generalist.

I've designed things that had to survive fairly different tests: fitness equipment that needed to hold up to real athletes pulling on it, ID card printers that had to work for years of daily use, military helmet mounts that had actual ballistic requirements, and sci-fi dice vaults that just needed to feel satisfying to open. Along the way I've machined aluminum, snapped more taps than I'd like to admit, cast resin parts in a shared studio until the fumes became a problem, and soldered LEDs into a 3D printed enclosure to make dice glow.

I also picked up web development along the way, first to build sites for family businesses, then full apps. It means I can build the companion app or e-commerce site around a product, not just the object itself.

If you need a prototype that's ready to show investors or manufacturers, this is what I do.
