I help organisations in utilities, banking, and government turn data into trusted information — and build the processes that grow it.
Define what good data looks like, measure where you fall short, and build the ownership structures that make it stick. Hands-on experience at Alliander, ING, and Liandon.
Governance frameworks only deliver value when people use them. I design and run the change programme alongside the technical work — stakeholder alignment, training, adoption measurement.
I work directly with data models, SQL, pipelines, and systems. No translator needed between business and IT — I hold both sides of that conversation.
Mergers and system upgrades had degraded meter data quality across the network. Built a central data reconciliation system for the high-voltage grid — pulling data from multiple sources, matching records across systems, and pushing corrections back. Designed data ownership structures and ran the change programme that made quality improvements stick.

Led the team responsible for implementing regulatory stress tests across ING's full €4 trillion credit portfolio. Built the data quality programme and delivered compliant Basel II reporting pipelines.
High staff turnover combined with a complex provisioning process meant critical knowledge kept walking out the door. Implemented a knowledge base across 4 departments and achieved full adoption — through early buy-in, pilot phases, and embedding it in daily work.
A small bash script that makes Claude Code speak its responses out loud. Pair it with voice dictation and you get a two-way conversation with your terminal.
A PHP script that catches contact form submissions, uses AI to draft personalized responses, filters spam, and saves ready-to-send replies directly to your email drafts folder.
At Devilsberg, we build software using Extreme Programming — with a twist. Humans navigate, AI drives. Here's how that works in practice.
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, built reporting systems for a €4 trillion credit portfolio, and helped improve the quality of service for a Telco. The common thread: complex environments that modern life is built on.
What drives me is the belief that reliable systems make a better world.
I'll get back to you within a working day.
