What I'm looking for

I’m seeking a remote role where I can use data-driven paid media expertise and AI-powered automation to reduce costs and increase output for a lean team.

At Phu Nhuan Jewelry Joint Stock Company (PNJ), I managed digital media across five sub-brands and improved blended ROAS by about 60% while cutting acquisition costs by 30%. I also grew revenue year over year and organic website traffic through paid media, testing, and SEO.

On my self-directed project, I designed and built a self-hosted, multi-agent AI marketing system in n8n for campaign planning, approval workflows, content generation, and scheduling. I’ve also built a Shopify storefront and marketing automation for a US-market e-commerce client, and I’m seeking a remote role where paid media and AI automation can reduce costs and increase output for a lean team.
