How we work

  1. 01

    Discovery

    We map your existing systems, data flows and business constraints. The outcome is a clear technical specification and estimate.

  2. 02

    Architecture

    We propose the architecture, API contracts (OpenAPI, AsyncAPI) and a migration plan — before the first line of code.

  3. 03

    Development

    We deliver in two-week sprints with automated tests, code review and a demo at the end of every cycle.

  4. 04

    Production & support

    We monitor the system in production, respond to incidents and keep improving it under the agreed SLA.
