What we do

Mobile, web and desktop app development gives users access to the same business processes across different devices. ORELSIS designs and builds apps for field teams, operators, customers and managers that integrate with enterprise systems. We shape the interface around the user's workflow and connect it securely to the back end.

Process

Four steps, measurable progress

  1. 01

    Know the user

    We identify the core flows by studying who will use the app, where and under what conditions.

  2. 02

    Prototype

    We build an interactive prototype, test it with real users and refine the design.

  3. 03

    Build

    We build the app and the required APIs and integrate them with your enterprise systems.

  4. 04

    Release

    We release via app stores or internal distribution and plan the next versions with usage data.

Technology

The technology we use
