About Me

The marketer behind the metrics.

I'm a performance marketing specialist with 4+ years of hands-on experience running paid media campaigns that actually move the needle. My background spans freelance client work, agency campaign management, and co-founding an eCommerce business — giving me a commercial perspective most marketers lack.

"I don't just run ads — I build attribution-accurate systems that tell me exactly what's working, then scale it with confidence."

My technical foundation in Computer Science gives me an edge when it comes to tracking implementation. I set up GA4 event tracking, GTM configurations, and Meta's Conversions API (CAPI) to ensure every conversion is captured and attributable — the kind of data accuracy that supports real scaling decisions, not guesswork.

Currently completing an MSc in Digital Marketing & Analytics at Dublin Business School, while actively working with Irish SMEs. Available for full-time roles from Summer 2025.
