Product Engineer building complete web products from product decisions and interface design through architecture, implementation, and release.

I combine full-stack engineering, UX, and product thinking to turn ambiguous problems into focused, production-minded software. I am based in Brazil and open to remote opportunities with international product teams.

A full-stack platform for small service teams to receive, triage, work, and close client requests without losing context across inboxes and spreadsheets.

• Multi-tenant authorization enforced at the database boundary
• Owner, team member, and client workflows
• PostgreSQL migrations, deterministic demo data, and production deployment
• 130 database-backed tests plus end-to-end browser coverage
