Hi, I am Jacob!

I work on GenAI at Meta.

In the past, I worked on Experimental Products and Facebook Marketplace Growth Team.

Before Meta, I worked for Microsoft where I helped to build the new Azure Management Portal, Azure Management Mobile App, Azure Search, and SeeingAI.

I occasionally speak at conferences around the World. You can find my talks here and on my youtube channel.

Sport and outdoors

I love biking and triathlons. I am an Ironman and USA Triathlon National Championships finisher. My favorite distance is the Olympic triathlon: 1.5k swim + 40k bike + 10k run.

I also enjoy hiking, skiing, soccer, martial arts and sailing.


I would love it if you follow me on Twitter and subscribe to my youtube channel.
