I got into cocktails during COVID and ended up with a shelf full of bottles I didn't know what to do with. So I built an app for that. Today's the day! Spritz is available on the App Store. Bar inventory, recipe matching, and an AI mixologist. Cheers 🍸

Beyond getting strings correct in localizing, the most difficult part is (was) collecting screenshots. Continued fun adding bits and bobs to my testing skill.

Continued efforts to build out better detection and annotation tools. Using SAM3, creating first pass annotations, then validating before kicking off additional active learning. Created a "swipe" feature set to swipe to approve/reject/skip annotations.

Playing with different annotation interactions, attempting to improve speed and comfort. Now using a couple ML methods to detect contours, then be able to trim or add to the polygon with limited interaction. Probably need to make an iOS app with pencil support...

Experimenting with animating sensor data. Eventually looking to build out predicted poses based on sensor data, and how that maps to detected activities. Boring, for now.

I've been thinking of new ways automated testing could be used. Today, I created a series of tests that goes through my customer flows in a variety of appearances. They take screenshots, finally creating a new webpage where I can directly compare various UI against each appearance.

I've been meaning to write this post for years, but the Square layoffs finally pushed me over the edge. This is surely one of my less popular convictions, but I earnestly believe that big companies getting smaller is rational because communication bottlenecks kill productivity and demoralize teams.

For my consumer CV/ML training app I added an MCP server for all the features a user could touch/use. Feels so powerful rationalizing through results, experiments and ideas, then queueing up multiple training "bets" to concurrently run and test at once.

Half of creating something new involves removing features you’ve already built for something that’s better. I swear I've rewrote this one user flow 4 different ways, liking each better than the last.
