I build the data functions that organisations need but don't have yet

Strategy, architecture, delivery, governance — the full picture. Not dashboards. The thing underneath that makes dashboards worth trusting.

I'm Özge — a Data & BI Lead with over fifteen years in this field. I run a consultancy out of London called Ezgius, and I work with organisations across Europe.

What I do isn't complicated to explain: companies call me when their data is scattered across too many systems, nobody trusts the numbers, and the reports take longer to build than the decisions they're meant to support. I come in, build the function — the architecture, the governance, the delivery process — and leave behind something the team can actually own and run.

I've done this for manufacturers, insurers, holiday parks, and fleet operators. The industries change; the pattern doesn't. Find the mess, structure it, govern it, hand it over.

Let's see if I can help

If your data is in more spreadsheets than you'd like to admit, or the reports nobody trusts keep getting emailed around anyway — that's usually where I come in. No pitch. Just a conversation about where you are and what it would take.
