Starting something new. After nearly 13 years @ Apple, I'm moving on to build something of my own. Working on one main product idea, plus a couple side projects. I'll also be doing some contracting work along the way when the fit is right. Looking forward to the challenge and exploring where this goes.

Getting more consistent about getting out for a walk daily. Been working toward walking every street in my city.

Teaching computers to see/understand the world (golf courses from satellite, photos, txt) has been some of the most rewarding and fun work I've done recently. I'm building out (on the side) Burgerater. For people that are interested in finding the best of a given food type. Limited folks can play the game on burgerater.com (desktop is best, working on that) and get access to the TestFlight.

Watch as post-it notes come to life! Blue notes spawn balls, pink notes bounce them, and yellow notes act as ramps. I made this fun projection mapping demo in two nights earlier this week, all in ChatGPT Sites with Work mode. 🗒️

27.1 has Duo support. But if you wanted to see what Apple apps looked like... They removed everything but Safari and Settings.

Wild seeing Brazil/Portuguese overtake US/English for one of my side projects. Localization matters because people being comfortable in the app they use matters.
Two circle charts showing Brazil at 42% language distribution, over United States at 23%. Second circle chart shows 40% Portuguese over 35% English.

Played with my v5 model to detect features (typically used just for golf courses) over my entire city/surrounding area. Very cool to see it extend into new uses.

I have a "long" run training running, about 16hrs in of about 30hrs expected. Such a freeing thing when the computers are churning and I can focus on next steps.

Picked up an Ultra 4. All the reasons I was considering adding an Oura (Longevity and Readiness) to my wearables are consolidated into a product I already love. Very excited.

Slowly been building out my ML annotation/training app while building @DewyGolf . Started with local, opened it up to your fleet of Macs, and now just added @runpod support. Eventually I want collecting, training and distribution of ML models built by you to be as easy as ordering coffee.
