Hanhan Sun

I’m an Overseas Marketing Manager with over 5 years of experience in overseas marketing and social media operations. I focus on Instagram and Facebook advertising, content planning, and international KOL collaborations to deliver measurable ROI growth.

At Hunan Aosom E-commerce Co., Ltd., I managed Instagram and Facebook content operations and grew engagement through campaigns like giveaways (600+ participants per campaign). I also oversaw a Spanish ad account (monthly budget $7,600), maintaining ROI above 13 and significantly outperforming industry benchmarks. I led global KOL gifting projects across 8 countries, improving efficiency by 40% through standardized workflows and templates.

Before that, at Shanghai Leyang E-commerce Co., Ltd., I operated Instagram, Facebook, TikTok, YouTube, and Pinterest, achieving 3% monthly follower growth. I independently sourced and managed overseas KOL partnerships by screening 100+ influencers monthly, securing 20+ collaborations with 5% engagement per post, and used data tracking and competitor analysis to drive 4–8% average engagement rates. I bring cross-cultural communication, data-driven optimization, and strategic project execution—along with the ability to train and manage remote teams for efficiency and scalability.
