A little about me

I build content around how people actually think.

I’m a creative strategist and growth marketer with a graduate background in psychology — I study why people trust, engage with, and influence one another, then build content and campaigns around it. Over 10+ years across performance marketing, creator partnerships, and digital growth, I’ve made scroll-stopping content that converts and grown a creator network from 0 → 4,000 at izyu. I work with beauty, skincare, tech/SaaS, and wellness brands — blending UGC, paid social (Meta & Google Ads), and audience psychology.
