Capabilities

What we know how to build, with code in production behind it.

This is what backs our advisory. Every capability on this page comes from software our team has already built: 45 repositories, two public projects in production and an internal portfolio we do not name but do draw on as experience.

45 Repositories built by our teamacross web, mobile, APIs, data and artificial intelligence.

What we can build

Eight lines of work backed by production.

Each one comes from a problem we already solved and that is still running. The public cases are explained in Projects.

    In production: Paintball Medellín (opens in a new tab)

  • Point of sale, kitchen and delivery

    Checkout, kitchen display tickets, QR ordering from the table, delivery fees and recipe-based inventory, for one or several locations.
