What we do

Business analysis, architecture and development are done by the same team, so the design and the finished system stay aligned.

  • Back-office and CRM systems

    Web-based enterprise and customer-management systems for core business processes: customer and master data, role-based access control, invoicing and online payment, reporting, and integration with POS and e-commerce systems, payment providers and external APIs.

    • PHP
    • Node.js
    • PostgreSQL
    • Oracle
    • MS SQL
    • Docker

  • Mobile and front-desk applications

    iOS and Android apps from a single Flutter codebase, plus tablet-based front-desk applications. Clients reach data through the back-office API; business rules and validation live server-side, in one place.

    • Flutter
    • iOS
    • Android
    • Web

  • System design and architecture

    Requirements, business process analysis, data model, integration and access-control concepts, system specification. On our own projects and as solution architects alongside partner teams.

  • Solution delivery

    We take on design, development, testing, rollout, data migration and further development. Classic or agile, to match how the client’s organisation works.

Budapest’s electric car sharing runs on our system

Since 2019 we have delivered GreenGo’s entire IT system: the back office, the Flutter mobile app, the telematics server that talks to the cars’ on-board units, the microservices and the Kubernetes cloud platform. We build it and we run it.
