About

Data-driven by design

I'm a digital professional with a strong analytical background and a hands-on approach to technology. I work at the intersection of performance marketing, data intelligence, and AI engineering — building systems that are both strategically sound and technically rigorous.

My work spans the full project lifecycle: from defining KPIs and campaign architecture, to building automated pipelines that reduce manual overhead and surface insights in real time. I'm equally comfortable in a spreadsheet, a data dashboard, or a code editor.

I have a particular focus on AI-powered automation — integrating LLMs and workflow tools to build intelligent systems that scale without proportional effort.

How I Work

The approach

01
Understand

Define objectives, map the data landscape, and align on what success looks like.

02
Analyse

Dig into the data, identify patterns, surface the insights that matter.

03
Build

Design systems, campaigns, or tools — then execute with precision and speed.

04
Optimise

Iterate continuously. Measure what matters and cut what doesn't.
