About Rosenxt

Rosenxt is a forward-thinking technology group originated as spin-off of the Rosen Group providing high-tech solutions for most challenging environments, including subsea, industrial, renewables and the integrity of the water and energy supply.

Callista: Impact Delivered

While Rosenxt was still in the process of separation from Rosen Group and building up a completely new business, Callista was asked to support establishing the future Data Platform.

Callista put together a senior team of architects, data engineers and consultants from Serbia and Switzerland to combine the proximity of a nearby Swiss partner with the scalability of our nearshore center in Serbia.

These Callista experts started with the design of the Data Lakehouse platform. As a first step, multiple vendors were assessed and the decision process was facilitated by Callista consultants and architects. Rosenxt decided for Databricks on Azure as their Data Lakehouse solution and the Callista team started with the engineering of the infrastructure platform as well as the integration of the first source systems.

Using an iterative approach while working closely with business stakeholders, the team could realize short terms benefits quickly.
