24 hours ago I didn't consider myself a developer. Today there's a live product taking real payments at ranknow.lol, built end to end with Claude Code. This is the actual, honest step by step of how that happened, not a highlight reel, the real sequence, including the parts that were hard....

Boris Cherny, who built Claude Code, has a confirmed daily workflow that sounds almost absurd until you understand the architecture underneath it. Phone as his primary interface, not a laptop. Five to ten active sessions running at once. Each one capable of spawning sub-agents, sometimes a few hundr...

Most research work is not thinking. It is reading, extracting, and cross-referencing, done manually, one source at a time, and it eats the hours that should go to the actual thinking....
