Xin chào, I’m Định!
I’m a data-driven Product Owner based in Hanoi, turning ideas into scalable experiences. I’ve been in tech for 15+ years, starting with game design at Minh Viet, then moving into e-commerce at DKT Technology, where I worked on Bizweb, now known as Sapo — basically a Shopify-like platform for the Vietnamese market.
Later, I went freelance and spent seven years at Gobiz building cross-border e-commerce products, followed by a short time at Authentic Education Hub, where I worked on products that blended education and e-commerce. Right now, I’m exploring blockchain and how it can be applied to public administration and everyday life.
My background is a weird mix of graphic design school, frontend dev, product ops, and eventually product ownership. I’ve touched Agile, Scrum, digital strategy, and enough code to be dangerous. I don’t really design anymore, but I still like building and tinkering with side projects when I can.
Outside of work, I vibe-code side projects with Claude Code. Most of them begin the same way: I notice a problem, think “how hard can it be?”, and then three weekends later I’m still tweaking CSS at 2am. Some of what we’ve shipped together lives on the playground page.
When I’m not staring at a terminal, I’m running slow kilometers around Hanoi, drinking too much coffee, or trying to explain to my kid why the thing on my screen is not Minecraft.
