  Profolio

  Active

  The portfolio platform this page is running on. Skills stay attached to the projects that use them, so the page shows evidence instead of a self-assessment. Ships a public portfolio, an application tracker and a résumé export typeset from the data rather than captured from the screen.

  Feira Livre API

  Completed

  Bot do Grupo

  On hold

  Scheduling bot for a neighbourhood football group — polls availability, picks the pitch time with the most confirmations, and stops asking once eleven people say yes.

  • Go
  • Docker
• 06KDC

  Kit de Componentes

  Archived

  An early attempt at a shared component library, kept here because the lesson is worth more than the code: it was abstracted before there were two real consumers, and both projects ended up fighting it.

  Innovatech Labs

  Jul 2024 - Present

  São Paulo, Brazil

  Own the billing surface end to end: checkout, webhooks, plan limits and the dunning flow. Cut failed-payment churn by moving retries off a cron and onto the provider's own schedule. Mentor two interns through their first production deploys.
