Financial Services

67%

Reduction in data processing costs

Legacy Oracle to Databricks Lakehouse Migration

A major European financial services firm was spending €1.8M annually on Oracle licensing and infrastructure for their analytics workloads. Query performance was degrading as data volumes grew, and their data engineering team spent 60% of their time on maintenance rather than new development.

We migrated their entire analytics platform to Databricks on Azure in 14 weeks — including 3.2TB of historical data, 47 ETL pipelines, and 12 executive dashboards. The new platform processes data 4x faster, enabled real-time fraud detection capabilities, and reduced annual costs by €1.2M.

✓ €1.2M annual savings✓ 4x faster reporting✓ Real-time fraud detection✓ Zero downtime migration

“BI-IT Solutions delivered what our internal team estimated would take 18 months — in just 14 weeks. The cost savings alone justified the project within the first quarter.”

— Head of Data Engineering

Logistics & Supply Chain

340%

Improvement in forecast accuracy

AI-Powered Demand Forecasting Platform

A pan-European logistics company was losing €15M annually to inventory waste caused by inaccurate demand forecasting. Their Excel-based forecasting process couldn’t handle the complexity of 6 markets, seasonal variations, and supplier lead times.

We built an ML-powered demand forecasting platform on Databricks that ingests sales data, weather patterns, economic indicators, and promotional calendars. The model refreshes every 15 minutes and achieves 92% accuracy — preventing €3.8M in inventory waste in the first year alone.

✓ €3.8M waste prevented✓ 92% forecast accuracy✓ 15-min refresh cycle✓ 6 markets covered

“The ROI was visible within the first quarter. This transformed how we plan across all our European markets.”

— VP of Operations

Healthcare

12x

Faster clinical data queries

Unified Patient Data Platform on Azure + Databricks

A healthcare network with 14 clinics was struggling with fragmented patient data across multiple legacy systems. Clinical researchers waited days for data queries, and GDPR compliance was a constant manual overhead.

We built a unified patient data platform on Azure Databricks with built-in GDPR compliance, role-based access control, and automated data quality pipelines. The platform consolidated 3.2M patient records from 7 source systems into a single governed lakehouse.

✓ HIPAA & GDPR compliant✓ 3.2M records unified✓ 12x faster queries✓ Automated governance

“They understood both the technical complexity and the regulatory constraints. That’s a rare combination in data consulting.”
