Available to hire
Hi, I’m Mariona, a private investigator and trusted beauty advisor who combines curiosity with a customer-focused mindset. I have a Bachelor’s degree in Private Investigation and extensive experience as a top-performing beauty consultant, particularly in Korean cosmetics, where I develop personalized skincare and makeup consultations while driving sales growth.
I’m fluent in English and comfortable communicating with international clients, have training in OSINT techniques and case work, and I’m passionate about applying investigative rigor to everyday client service and problem solving. I also know French and basic Chinese and love blending my investigative skills with creative solutions in fast-paced retail environments.
