Software engineer — backend & product
About me
I build backend systems where the business rules are the hard part. At Magalu Cloud that means Go services for internal financial operations — charges, invoices, refunds, reconciliation — turning billing behaviour that starts out ambiguous into explicit state transitions, eligibility checks, audit fields and tests that fail loudly when someone changes the rules.
Outside work I ship small products end to end: a running coach whose weekly prescriptions come from an LLM but are validated before an athlete ever sees them, a crossword generator that refuses to return a page unless a solver proves all 150 cells are filled, and a photo tool that has been running on a small VPS long enough to have opinions about Caddy.
