Hi! I'm Jer.

I'm an engineer, product designer, and entrepreneur.

I'm currently the Head of Hardware for R-Zero Systems where I was the first engineer and built the hardware team and manufacturing capabilities from the beginning. In our first two years, we launched the Arc, Beam, and Vive. R-Zero was named a World Changing Idea by Fast Company and made Forbes list of the next billion-dollar startups. R-Zero has raised $170M in venture capital funding.

I am also the founder of Blossom Coffee Inc. Blossom is an engineering consultancy and intellectual property development company with the mission to make good coffee more accessible. At Blossom, we launched the Blossom One Brewer and served coffee to 2Chainz on GQ's Most Expensivest series. We developed and launched the Dripper and filters for Blue Bottle Coffee. We lead R&D for the Ninja Hot and Cold Brewed System.

In 2018 the Blossom team joined Fellow Products full-time to expand their engineering capabilities. At Fellow, I lead the development of the Ode Brew Grinder, the Shimmy Coffee Sieve, and the Prismo. I also helped recruit and grow their product development team.

I am honored to have served as a judge for the USA Coffee Brewer's Cup Championship in 2020, 2022 and 2023.

I write a lot and occasionally publish things. You can check out some of my articles on Brokeass Stuart.
