What I'm looking for

I’m looking for a product role where I can own strategy from user research to GTM, collaborate cross-functionally, and use data to iterate fast—ideally in B2B/high-tech with clear growth goals.

I’m a Product Manager with 4+ years of experience in high-tech and B2B marketing, focused on bridging business goals and product execution. I’m known for identifying user problems, defining product strategy from scratch, and aligning cross-functional teams to bring products to market with data-driven decision making.

In my personal work, I led Lang, a mental health app, where I validated a Vietnam market gap and built an AI-powered companion concept through user research and competitive analysis. I developed a full UI/UX prototype using Google Stitch and designed a GTM strategy with NGO partnerships and a two-phase revenue model—learning that distribution and long-term trust must be validated before monetization.

Previously, I researched and planned a Digital Attendance & School management app, running a pilot plan in Da Nang and refining the go-to-market after discovering B2G procurement barriers. I also bring execution strength from marketing and analytics roles at Sky Global and Tech Pro JSC, plus end-to-end ownership as Co-Founder & Brand/Operations Lead at Kan’s Lounge.
