06 —About

Two engineers, fewer layers

Ferrun is two senior full-stack engineers based in Porto, Portugal — around five years each building data-intensive B2B applications. We work mainly with .NET, Angular, SQL, Python, and Azure. After years inside product teams, we now take projects on directly: same standards, fewer layers.

  • Porto, Portugal
  • Forged to last.
