Data engineering and BI


We have identified while working with clients across industried that the hardest part on BI reporting, ML or model development is often not the task itself, but the data management around it. The data engineering is often the most challenging part of the problem.

Cloud environments are complex

These environments offer huge scalability, flexibility and potential cost savings. But the cloud environments can be also too complex to work with.

Missing data centralization

Data exist in many legacy systems across the organization. The data centralization is required in order to be effectively used.

Advanced data processing

Some calculations or reports are too advanced to be created by self-service BI tools like Tableau or Power BI. These problems require complicated data processing or transformation routines developed with the emphasis on large data scaling and efficiency.


Our data engineers and software developers help you to build a solid data architecture. We could help you with:

  • Design of your cloud architecture

  • Building your data lake or data warehouse

  • Data preparation and cleansing for your BI analytics or model development

  • Automation of the data ingestion

  • Custom reports and dashboards

  • Building of data transformation and calculation engines


We have identified, developed, and successfully implemented solutions for both large and small companies, always with the emphasis on maximizing the business value.

IFRS9 Provisions Plausibility Engine

In early 2018, a new methodology for the calculation of provisions for Expected Credit Losses (or ECL) under IFRS9 for the banking sector came into force. Our team was tasked with implementing a solution for the retail credit exposures of Raiffeisen Bank International (RBI). The calculation is used to check the plausibility of results provided by each RBI subsidiary bank.

"This was a clear example of agility. CloseIT was presenting a steady development in regular iterations as the tool was progressively taking shape. The speed of development was impressive. From zero to functional IFRS 9 ECL prototype in 3 months!"
Deyan Ivanov, Head of Retail Risk Methodology & Validation at Raiffeisen Bank International

Credit Risk Stress Testing Framework

We have created a unique solution for recurring stress tests in credit risk Raiffeisen Bank International, which allows us to define our own test scenarios for simulation of portfolio development and calculations of individual Risk Parameters RWA or ECL. Our application was successfully used for EBA stress tests in 2018 and continues to be extensively used for other stress testing needs by internal or required controllers.
