SalesOS is the software I founded for sales pros. The clearest proof of what I can build: a complete web application, in production.

  • AI coaching on calls
  • Public, verifiable proof (track record)
  • Built-in invoicing
  • Acquisition through content (SEO)
What we delivered

The application

  • Full web app (authentication, Stripe payments)
  • Pipeline, meeting tracking, AI coaching
  • Verified public track record
  • Electronic invoicing (Factur-X, CPF)

  • Landing pages and conversion funnels
  • Vercel and Supabase infrastructure
The result
