How it started
I studied computer networks at UIT in Ho Chi Minh City. In 2020 my team built a smart home out of cardboard, a Raspberry Pi and a handful of sensors. It ran perfectly. The first person outside our group who tried it opened the app and couldn’t turn on a light. Nothing in my degree had prepared me to find that interesting, and I found it very interesting.
What followed wasn’t a straight line
2020 to 2026
- 2020Started in graphic design: a remote internship, then branding and packaging.
- 2022Graphic designer at PNK Media, with a multimedia diploma alongside.
- 2023Taught graphic design fundamentals at VCI College to a class of more than 50 students.
- 2024UI/UX designer at Mona Media: client sites, web apps and the system underneath them.
- 2025Moved to Sweden for a master’s in User Experience Design at Jönköping University.
- Nov 202546 students tried an early version of Regula at a hackathon at LUT University, Finland.
- 2026Studied Regula with 54 students, finished the master’s in June and moved to Stockholm.
Now
My thesis became Regula, an AI-enhanced learning platform that Nikodem Płocki and I designed and built, and that I then studied with 54 students. The findings weren’t the ones I wanted. People planned far more and didn’t finish more, and the validated questionnaires registered none of it. Watching that happen was worth more than any of the design work.
I now work between research and the interface. Having once been the person soldering the thing helps more than I expected, mostly because I know what it feels like to build something that works perfectly and is unusable.
Resume
I design interfaces from user research to working prototype, and I build a fair amount of it myself. Master’s in UX Design from Jönköping University, 15 months of agency product work before it, and three years in graphic design before that.
Selected work
Regula
- AI-enhanced learning platform. A teammate and I designed and built it with Lovable on React, TypeScript and Supabase, and I led a two-week study with 54 students across two waves.
- Findings: AI support roughly tripled task creation and raised active planning days, but completion rate did not follow. Interviews described deeper reflection that the validated scales missed. Paper in preparation for PERSUASIVE 2027.
- 46 students tested an early version at a hackathon at LUT University, Finland (SUS 66), and the leaderboard and streaks came from their feedback. Science Park Jönköping Award for Best Business Potential, 2026.
Mona Soft and Host
- Design system across two products of the same company. Buttons, colour, spacing and grid shared; visual style kept separate.
- Built a page template that later designers used to build new pages without starting from an empty artboard.
SMART Living Solution
- Interface for a smart home my team built from cardboard and a Raspberry Pi in 2020, redesigned once I could see why the first person outside the team couldn’t turn on a light.
Experience
UI/UX Designer, Mona Media, Ho Chi Minh City

- Worked directly with a developer on performance, cutting motion that cost page load on a search-driven rebuild.

Outside work
I borrowed a snowboard from Fritidsbanken halfway through last season and finished it on a red run at Isaberg three weeks later. Toeside carve is fine now. Heelside isn’t.
