For 5 years, we have worked together with architecture and middleware teams at OSDE to design, implement and operate in the corporate middleware platform of the organization which gives support to the integration of more than +250 applications and all critical mission processes. The project included the definition of policies and practices of middleware services administration, identification, design and development of integration services, implementation of corporate ESB and platform operational support. We also implemented the corporate BPM, a data private cloud platform, an indexation engine and an event processing platform in real time.
