Hey, I’m Felipe.

Most of my work is Next.js, TypeScript and Node. But the part I actually rely on sits underneath the framework: components have a lifecycle, state has an owner, and something has to decide when to re-render. React and Angular answer those questions differently — they aren't different problems. Moving between them has never been the hard part of a job.

Lately, the hard part has been deciding what an LLM should be allowed to decide. Anything that can be written as a rule should be a rule: deterministic, testable, identical every run. The model gets only the questions that genuinely need judgment — and it gets them narrowly. It doesn't hunt on its own; it rules on candidates the deterministic layer already found, and it has to show its reasoning. A schema guarantees the shape of the answer; the prefilter and that reasoning are what make the content auditable. That split is the architecture behind both BlackLetter and Strategic Council.

I've worked remotely with US teams, and I'm comfortable owning a feature end to end — API, database, interface, and the failure paths nobody demos.

Open to senior remote roles — feel free to reach out.
