Senior Technical Writer at iFixit, technically, since early 2020.

Modern personal technology is constantly changing—and I’m so stoked to be on the forefront of its investigation! I write helpful repair guides and contribute to iFixit’s online ecosystem, making the tech world a better place one word/picture/sarcastic comment at a time.

About Me

I graduated in late 2019 from the best school in the entire world Cal Poly San Luis Obispo, with a bachelor’s degree in mechanical engineering. During my stint there I gained an incredibly satisfyingly deep understanding of the way the world works, and how to explain it to others with thorough documentation and simplicity. I enjoyed this aspect (enter tech writing) and now I get to do it all day long!

Senior Project!

I’ve always loved fixing my own gadgets and the casual deep-dive into problem-solving rabbit holes, so I am truly excited to have an outlet!

When I’m not working (checking Craig’s How To Unclog A Toilet guide for spelling mistakes), I love exploring the beautiful central coast, taking photos, playing board games & poker, looking at cars I can’t afford on Craigslist, watching Vince Gilligan’s TV shows, building way too many computers, and traveling the world with my wife!

Favorite Technology Things

  • Aluminum computers
  • AirDrop
  • High pixel density displays
  • Wireless music
  • Manual transmissions
  • Anything that’s not FaceID
  • SFF PCs

Thanks for sticking around, and happy fixing!
