Teaching people how to build and making learning apps with Build First at buildfirst.ai.
I wrote a blog post about the pop-up app that I vibe coded for my block to help manage snowstorm support for our neighborhood.

We just filled our first request!!
Amazing to see hyper-local pop-up communities have some real value in highly specialized settings. let's see how the week goes...
anyone here interested in pop-up community marketplaces for emergency support?
i vibe coded this VERY MVP mini-app for my block last night: https://stormlink.manhattan75.nyc/

As a 1-person company who hasn't (yet) figured out how to get my AI's to work on my behalf while I'm OOO, I couldn't figure out how to *NOT* check email from Cancun.
So I just left my laptop at home, deleted every app off my phone, and hoped for the best.

BIG news on the block...tonight we elected our 7-person board of directors!
Feeling pretty proud how we've been able to catalyze a community that's big enough to activate enough members on the street for a formal board in just 18 months.
It's a pretty special thing to see. <3

Here's a new one... stuck on how to make a key decision? Try simulating a conversation with future you! 😵💫

This has been scheduled in NYC for March 4.
It'll be a small-group thing to start (max 24 builders, vibe coding). The theme for the day will be personal operating systems. DM if you're interested!

Some of you may have seen this last week, but with all the changes going on in crypto right now, I thought i'd pull out this little snippet from an essay I wrote last week.
Working among crypto-native teams for three years is how I learned to build. You taught me how to weather the storm and keep the drumbeat going, e...
