Design it. Code it. Sell it.

Seven years shipping products people actually use: over a million on Math Formulas, and 100K+ on mess.vn, which I founded and grew without a single ad.

Product Designer / Ho Chi Minh City / Open to new roles

A designer who reads code, a founder who reads the invoice. When a design ships, I’m the one paying the server bill behind it, and watching how many people come back the next day.

✺ About

A designer who reads code,
a founder who reads the invoice.

Portrait of Lê Tuấn Anh

Lê Tuấn AnhHo Chi Minh City

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. I don’t stop at handoff: when it’s faster, I build it myself with AI-assisted development, this site included. Back in secondary school, my blog ranked among the top 2,000 websites in Vietnam, and Fshare gave me my first paid design job.

02

Founder instincts

I shipped mess.vn end to end, with Claude in my daily design and development workflow, 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.
