Development of an integration layer responsible for synchronization and interacting of client high-level business applications with existing solutions and databases in the IBM i (AS/400) system:
- Backend development #Java #AS/400.
- Functional and system testing, Unit-tests #JUnit #Mockito.
- Suggested and implemented best practices: code style, branching strategy, and REST API.
- A distributed team from different time zones and countries (North America, Asia, Europe).
- Working directly with the AS/400 system is a complex task that requires non-standard knowledge in the internal specifics of the system.
- High performance with possibilities to scale and balance the load was ensured.
