Hello - I’m Toni Klopfenstein.

The easiest definition of me is: “Jack of all trades, master of none, but oftentimes better than master of one.”

Over the years I’ve worn a lot of hats professionally: developer relations, engineering, QA, product development, management, and technical support. I understand the full product and development lifecycle, from the person filing the bug to the person fixing it to the person deciding what gets built next. I love solving problems and removing friction points to make the learning and use of a product easier for customers.

I’d love to hear from you — whether it’s about work, open source hardware, or just to say hi.

The best way to reach me is on LinkedIn.

That being said, I prioritize being off of the computer, connecting with nature, and disconnecting from the dystopian pocket and desktop machines. I do not expect or demand instant responses from others, and I appreciate others granting me the same patience.

Website Revamp

Sun, 12 Jul 2026 00:00:00 +0000

Personal websites are, much like everything on the internet, subject to rot.

To say I have let this site linger and languish would be an understatement. Blame it on laziness, exhaustion, whatever you’d like, but mostly it’s because it’s just one more thing to keep updated between internal resumes, LinkedIn, external resumes, bills, mental and physical health, maintenance of relationships with friends and family, etc etc etc. And frankly I didn’t care that much.

About

Thereminus Rex is a giant, blinky pseudo-theremin that you dirty hippies play by using your whole body, or your friend’s body, or your friends’ bodies.

Thereminus Rex lives to disprove the propaganda we’ve been taught that you need talent and skills to create enchanting music.

T. Rex allows anyone to create beautiful (if only to them) musical sounds by miming, hula-hooping, stretching, vigorous gesticulating, or dancing in front of a set of proximity sensors that control the pitch and volume (within reason!) of the sounds emitted. A quiet-time mode enables the users to control the speed and brightness of lights on the structure to provide a more contemplative experience. Different types of sound outputs can be selected by the user as well.
