What an amazing week in Seattle for the first global AWS Heroes Summit! As a former AWS Hero myself, I continue being impressed by this unique group of people.

I'm so proud of the show my fiancée @taylorjacobsen, the community team, and all of AWS DevEx put on!

At the recent AWS re:Invent 2025, I taked about the use of generative AI foundation models on local/edge devices and AWS IoT Greengrass in the era of Physical AI.
I've received a summary of the session content, so I'm sharing it!

2025 has been the most gratifying year of my career. Felt privileged to share the #AWSreInvent stage with @abaibourova.bsky.social and tell the true story of how I went from #AI skeptic to power user, sparking a company-wide grassroots movement of tens of thousands of #Amazon builders.
