About

Strategy meets execution

For the past decade I’ve worked where marketing strategy meets technology, leading enterprise automation programs and shipping the front-end work that makes them perform. My work has been shortlisted by the B2B Marketing Awards for Most Commercially Successful Campaign and Best Integration of Sales and Marketing.

From building pixel-perfect landing pages seen by millions to architecting nurture journeys that triple engagement, I bridge the gap between creative vision and measurable results.

Mentorship

Sharing knowledge

I believe the best work happens when entire teams level up together. Beyond delivering projects, I actively coach colleagues and clients on the tools, techniques, and thinking behind modern web and email development.

Whether it’s walking a marketer through HTML email architecture, running a live walkthrough on responsive design principles, or pairing with a junior developer to debug a tricky layout. I’m at my best when I’m helping others build confidence in their own technical skills.
