How we do the third-party software integration

Step 01

Sprint planning

We precisely analyze and plan the sprints of how your 'as-is' state converts into the desired result. You get the defined way of the integration process, API/facade documentation, and adapters patterns.

Step 02

Tech architecture

Code architecture is our specialty! We write it following best practices and check the functionality via unit tests. Stand-ups, weekly demos, and reports ensure everyone is on the same page and can voice their concerns.

Step 03

Service integration

We create a sandbox environment, CI/CD, as well as cover all the code and transaction tests. As a result, you get a 100% guarantee that every integration process is properly secured and handled.
