I was the first employee at Mashgin and now work on product and operations there. I also run a family office that invests in public/private companies, and publish "Berkshire Hathaway Letters to Shareholders", the only book with Warren Buffett's full letters.

My primary interests are:

• The intersection of engineering and user experience design.
• Automating the things that life's too short for.
• Researching and investing in good businesses of all sizes.
• A handful of other topics I'm not ready to share yet...

The best places to follow me are on Twitter or my personal blog (some posts also on Medium). You can find me in Silicon Valley and Utah.

Past projects:

• Berkshire Hathaway book / poster / kindle
• Atlastory — an open-source app that visualizes history on a map
• Blue Chip Stamps letters — letters of company Charlie Munger ran with Warren Buffett in the '70s
• HikeHero — map-based trail searching: filter by length, difficulty, proximity to trailhead [temporarily shutdown due to loss of one of the map providers]
• Other random software projects on Github
