Operator and builder · Buenos Aires, Argentina
I build the products I keep wishing existed.
I spend my days as an operator in fintech and crypto: institutional onboarding at Binance US, COO of a small fund, now investment analysis at Riverstone. I spend my nights shipping software. Same instinct in both, which is finding the part of a process that is broken and rebuilding it until it works.
Most of what is below started as a problem I had personally. A wall of climbing holds I could not read. A wardrobe full of plastic. A supplement I could not find. I build the first version fast, use it myself, and keep the ones that earn it.
Right now
- Building a Lemon Squeezy billing layer that every one of my apps can share.
- Turning Timeglass from a private tool into something other people can install.
- Open to talking to teams building in fintech, payments, or crypto.
