About

I help retailers make hard technical decisions around VTEX.

  • What should live inside VTEX?
  • What should be solved with external services?
  • How do you integrate ERP, OMS, WMS and payment providers?
  • How do you stop customizations from turning VTEX into an unmaintainable system?

At Valtech I lead architecture and delivery on VTEX IO, FastStore, checkout, payments, logistics, search, APIs and middleware, close to the code and to stakeholders.

Having worked inside VTEX and on enterprise systems taught me to turn architecture into solutions people actually ship.
