Blog

I write about what I pick up along the way: building product with AI, leading an engineering team and raising two German Shepherds. Remote, from El Salvador.

  1. 7 MIN READI don't just review the agent's code anymore. I ask for proofSix Playwright flows that leave a screenshot, video and trace on failure. In CI on every PR and every deploy. And four times the evidence proved me wrong.
  2. 7 MIN READI made a Nintendogs of my dog101 blended shapes, 10 layers of fur and one day with Claude. From the side it's Dante; from the front, not quite.
  3. 6 MIN READSeven years remote: impostor syndrome didn't leave, but it's a lot smaller nowSeven years working remotely from El Salvador for US teams. Impostor syndrome didn't go away all at once, it just kept getting smaller.
  4. 6 MIN READNobody reviews their own code well, not even an agentThree bugs that passed tests and review without looking odd. A fresh reviewer, human or agent, won't see them without knowing something the author didn't.
  5. 11 MIN READMy subagents reminded me of Naruto's shadow clonesI built eight subagents across two repos. In 18 hours they ran 27 times, 11 as real agents: what I delegate, what they found and what I still don't know.
  6. 7 MIN READMy prompt couldn't add, and my eval didn't say whyI built an LLM scorer with a threshold I never measured and eyeballed it until something showed up. Two weeks later: 39 labels and a bug in the prompt.
  7. 4 MIN READHow this blog is builtNext.js with static export, MDX posts inside the repo and no external services. Why I picked the simplest option and what I left out on purpose.
