Marketing Engineer.
I turn manual work into systems.

I'm Dimitrios. For over six years I've worked in-house, at agencies and as a consultant. Today at Estée Lauder Companies I build AI agents, API pipelines and Power BI dashboards that brand teams use every week. Underneath that is hands-on paid media, GA4 and GTM experience and a habit of automating whatever slows a team down.

What I do

Where media, data and engineering meet.

Most marketing teams lose hours every week to copying exports, chasing data and building the same report again. I build the tools that take that work off their plate.

AI agents & automation

Agents that write performance reports, standardise brand submissions in mixed formats, and track retailer and competitor promotions without anyone copying and pasting.

Data pipelines & dashboards

From API to a dashboard people actually use: paid media data pulled into custom dashboards, Power BI suites for trading moments, and Looker Studio reporting built to run itself.

Performance media & measurement

Paid search, paid social and retail media with budgets up to €400K a month. GA4 and GTM set up properly, so the numbers you optimise against are numbers you can trust.
