Contact

Email is best. I reply to everything that is not spam.

The fastest way to reach me is by email at [email protected]. I read everything that arrives there and usually reply within two business days. I am in Brazil (UTC-3) and I am comfortable in English and Portuguese.

Good reasons to write

  • Backend and API design questions, especially around Node.js, TypeScript, and relational databases.
  • Consulting or contract work on web applications that need to be reliable and maintainable.
  • Corrections or follow-ups on anything published on this site.
  • Speaking, mentoring, or open source collaboration.

I do not accept unsolicited sales pitches or link exchange requests. If you are an automated agent acting on behalf of someone, include who you represent and why you are reaching out.
