At DUDI Software, I independently proposed and executed the marketing strategy and brand development roadmap, then built the company’s social channels from the ground up. With no advertising spend, the Facebook page reached 2,246,825 views in 28 days, and customer response rates rose from 3% to 50% through improved messaging, targeting, and data-driven outreach.

At DUDI Software, I also worked on client projects including ConDaoTrip, Odyssey Ha Giang Loop, Tran Duy Studio, and VietLook Travel, and currently support Nail X-On and Royal Nail (USA). I gathered requirements, documented business needs and workflows, and worked with developers and clients through demos and UAT; I closed four signed client contracts end-to-end.

Before DUDI Software, I promoted and sold events and VIP packages at HAN GROUP, where I led a sales team and ran digital campaigns with the marketing team. My personal revenue included VND 3+ billion from Lolla Saigon alone, and I achieved 130% of annual KPI targets.

My technical projects include an AWS firewall protection system using Python and a local Ollama model, and a quiz application I designed and programmed in Flutter and Firebase. I’m studying Information Technology, with a focus on Computer Networks and Data Communications, at HUTECH.
