// hi, I'm Sebastian
I usually go by @derkinzi. A marketer turned developer and founder, I write about what I'm building, what broke, and what I'd do differently. More about me.
Fable found a permission bug in ContentIn during a review. We fixed it. The same day, a fresh account signed up and systematically probed our API for the same kind of thing. Coincidence?
How I replaced the 256 GB SSD in my base model M4 Mac Mini with a 2 TB drive for around $300. The swap, the clunky DFU restore from my laptop and the 3 hour backup.
Weeks 2 and 3 of maxing out Claude Code. Pepelly and Take stuck in App Review, Android next, SEO bots running on the Mac Mini, a new Keylogs tool and a power cut while I was on a road trip.
This week's build in my max out Claude Code challenge. Take by ContentIn, a Flutter app for one-off LinkedIn posts, designed and built by Claude, iterated on from the spa.
How I run all my projects from a Mac Mini. One Git repo per project, one Claude Code session as PM and dev lead, Opus sub-agents, tmux, Tailscale and remote control from my phone.
