Case Studies

ING — Regulatory Scenario Reporting

Team Leader | Banking

The Challenge

After the 2008 banking crisis, regulators required continuous stress testing to protect the financial system from future shocks.

My Approach

Led a small team responsible for implementing these regulatory stress tests. We worked with ING's full €4 trillion credit portfolio to run scenario calculations and deliver compliant reporting.

The Impact

Helped ensure ING met regulatory requirements — keeping the bank audit-ready and contributing to broader financial stability.

Telecom Italia subsidiary — Knowledge Management System

Program Leader / Change Manager | Telecom

Key Challenge

High staff turnover combined with a complex provisioning process meant critical knowledge kept walking out the door.

What I Built

Implemented a knowledge base across 4 departments, each with its own structure. Trained staff on retrieval and onboarded knowledge experts to maintain their sections ongoing.

Results

Embedded knowledge management into the organization — reducing dependency on individual expertise and improving onboarding.

Liander — Data Quality Engineering

Data Quality Engineer | Utilities

Our Challenge

Mergers and system upgrades had degraded the quality of meter data across the network.

My Contribution

Consumer market: Built reports to identify data issues and drive systematic fixes. High voltage network: Designed a system that pulled data from multiple sources, matched records across systems, and pushed corrections back — improving data quality at the source.

Outcome

Tens of thousands of data corrections implemented. For high voltage, created a single point of truth across previously siloed systems.

About

I'm Erik Ros — I build teams and systems for organizations that keep things vibing.

My background spans utilities, banking, and telecom: society's connective tissue. I've led teams, fixed data quality across critical infrastructure (Liander), built reporting systems for a €4 trillion credit portfolio, and helped improve the quality of service for a Telco (Telecom Italia). The common thread: complex environments that modern life is built on.

What drives me is the belief that reliable systems make a better world.

Right now is an exciting time to do this work. Europe is asserting itself on an increasingly competitive world stage. AI offers new challenges and opportunities. The tools have changed, the stakes have changed, and I'm here for it.
