About me

Strategy meets creative execution.

Years in marketing

Agency & in-house roles

I've spent the last three years working inside brands and agencies — writing copy, building campaigns, managing email lists, coordinating shoots, taking client calls, setting up funnels, and making sure nothing falls through the cracks. Sometimes all in the same week.

I work mostly with founders and small teams who need someone they can trust with the full picture, not just one piece of it. I care about the work, and I genuinely enjoy the creative and strategic side of what I do.

The way I work is pretty simple: I ask the right questions upfront, keep you in the loop without you having to chase me, and flag anything worth flagging before it becomes a problem. Clear communication isn't an add-on — it's how good work actually gets done.
