I quit the best job I ever had to try and build what I wish existed in the world. Two projects I'm working on now: 1. The Peterman Pod - When I first started at Meta, the career stories of incredible engineers always inspired me. I aim to share transparent career stories that I wish I had more of back in the day: https://creators.spotify.com/pod/show/peterman-pod There are still many engineers who are heros to me that I'd love to bring on the show one day! 2. Compose - I could never really find what I wanted so I'm building the ergonomic keyboard I wish existed. Pictures of our prototype here: https://read.compose.llc/p/our-keyboard-design-reveal I've earmarked ~6 months of living expenses to fund this new career direction. I'm going to give it my all to see if it's sustainable. Thank you for your support, working on my passion projects is something I’m only lucky enough to consider because of you all 🙏 If you're just curious to follow along generally, I'll share occasional updates everytime I have something interesting to share here: https://www.developing.dev/
