Cloud PC is hard to explain, so I led with what it does for you, and made the app ask first for the one thing that decides how it feels: your nearest server.

About
A designer who reads code,
a founder who reads the invoice.
Coding since age eight. 100+ tech awards before 18. Then came engineering, operations and business. Product design is where all three meet.

01
Developer roots
I design with the build in mind, so engineers get screens they can ship. At Atomiton that meant handoff-ready specs for a US team working async. When it’s faster, I build it myself with AI-assisted development, this site included.
-
02
Founder instincts
I shipped mess.vn end to end and grew it to 100K+ users and $11K+ peak monthly revenue on zero ad spend. Running it taught me to read the numbers and keep AI costs lean. A beautiful screen that doubles the inference bill goes straight back to the drawing board.
-
03
Client work
I’ve shipped for teams in the US, Canada and Vietnam, from AI infrastructure dashboards in Silicon Valley to Math Formulas, a formula app for students used by over a million people.

04
What’s next
I designed the payment flows and paid tiers of my own product, so monetization is something I’ve shipped, not just studied. Next: going deeper into AI products, revenue experiences and complex workflows.

Notes from the craft.
Milk tea, a bowl of phở, a red envelope at Tết. Everyday things that turned out to be product lessons.
người dùng không đọc đâu
Người dùng mở app lên vội chẳng khác nào đang chạy xe máy giờ cao điểm, trong khi tụi mình lại cứ hồn nhiên dựng mấy cái popup dài ba đoạn bắt họ đứng lại đọc.
kỹ năng bị coi thường nhất của designer: xóa
Cứ gặp vấn đề là tụi mình lại theo phản xạ vẽ thêm nút, thêm màn hình, chứ hiếm khi chịu dừng lại hỏi: có cái gì thừa xóa bớt đi được không?
mặc định là quyết định thay người dùng
Hầu như chẳng ai rảnh mở phần Cài đặt ra chỉnh lại đâu, nên người thiết kế chọn sẵn phương án nào thì coi như đã quyết định giùm người dùng luôn rồi.
