About my work

What I do

My work sits across user acquisition, product positioning and retention. I shape go-to-market strategy, run paid social and creator campaigns, and build the lifecycle flows that keep users active.

Over the last four years, I’ve worked across gaming, proptech, media and entertainment with teams like fan iq, Hochela and Omo Studios.

I run campaigns, fix underlying mechanics, and do everything in between, whether that’s lowering CAC on an established channel or building a regional expansion playbook from scratch.

About me

Built on curiosity.

PLAYER 1

Growing up, I loved playing games, mostly Super Mario Bros. with my family. That’s where my curiosity about why people love the things they do, and how great products leave a lasting impression, really started. And it’s never gone away.

I started out as a creative, and at my core, I still am. I channeled that into freelancing first, and later into DFRNT.ENT, curating experiences and building a space where young people could come together and just be themselves. I had to figure out what made people care, what made an experience worthwhile, and what made them actually pay for it. Those lessons have grown into a drive to be part of a team creating something valuable for people everywhere.

I see marketing like a football team sheet: different players, each with a role to play, and I build campaigns the way a manager builds tactics.

Outside my work

If I’m not working, you’ll probably find me on Football Manager. My best save is still winning the Champions League with Crystal Palace on FM24. In real life, I’m a Chelsea fan and I love analyzing football games.

I’m a sucker for great music production. I listen to a lot of The Weeknd, Brent Faiyaz, and Frank Sinatra Jr., and right now I’m obsessed with Ludwig Göransson’s score for The Odyssey. I also keep rewatching Spider-Man: Into the Spider-Verse, and I love animated series like Neon Genesis Evangelion and Family Guy (Seth MacFarlane is a genius).

I speak English and a bit of French (just enough to get by), and a day doesn’t go by without a bottle of Pepsi.

Let’s build
something incredible
