Progress Log

April 2026 — Week 1

✓ What Actually Happened

  • Built solobuilder.ai in one day (Next.js 15, Vercel, Beehiiv integration)
  • Built APEX Kitchen Architecture — 9 specialized content engines (Iron Chefs): Research, Blog, Newsletter, Author, Technical, Trend, Social, Academic, Due Diligence
  • Integrated LightRAG knowledge graph: 19,824 entities, 27,985 relationships
  • Published first Blog Chef article: "7 Reasons GitHub Repos Are Non-Negotiable for Solo Founders" ($0.23 cost, 3 minutes, 1,883 words)
  • Built publishing pipeline: one-click publish/republish/unpublish from Command Center
  • Built 10-question AI Assessment Quiz lead magnet
  • Set up custom email (richard@solobuilder.ai) with SPF/DKIM/DMARC
  • 74 automated tests passing
  • 83 Notion documentation pages

✗ What Didn't Work

  • Subagent-driven development cost $172 in one day (switching to inline execution)
  • LightRAG migration took overnight due to one bad chunk in retry loop
  • Blog Chef frontmatter didn't match site format (fixed: delimiter, date quotes, H1 stripping)

Key Decision

Build the engine first, then produce content. Not the other way around.

What's Next

  • Publish 2 more articles using Blog Chef
  • Send first newsletter using Newsletter Chef
  • Resume LightRAG migration for remaining chunks
  • Start weekly publishing cadence

Weekly updates go to the newsletter first.
