Proof, not just claims

Deep-dives into the systems built to demonstrate hands-on mastery: architecture, decisions, and trade-offs, not just a summary line.

Selfwright

Incubating

A career operating system built on one constraint: every output traces back to verified evidence.

Job-search tools optimize for volume and keyword-fit. Selfwright starts from a locked evidence registry and produces only what it can verify, then stores every decision made along the way.

$0/month recurring cost, running entirely on Cloudflare's free tier
Three equivalent content-editing paths — file, Claude Code, or a browser UI — no seat-priced CMS
