I design and build web apps.
For founders, teams and sports communities, from first sketch to a fast, polished launch.
Write to hello@thien.so, or see what I’ve built below. Away from the keyboard I coach tennis and pickleball.
In use today
Five sites people open every week: a league, a store, a sports platform and more.





What are you building?
Pick the closest and see one I have made like it.

Season signups, schedules, live standings and stats, run by the people who run the league.
Players find partners at their level, teams keep their games and chat, clubs run ladders and tournaments.
A catalogue people enjoy browsing, quick to reorder from and fast on a phone.
The menu, the hours, and order-ahead pickup that follows the kitchen’s clock.
Services with prices and times, and booking in a few taps.
Case studies with before-and-after sliders, and an estimate form that asks the right questions.
Pricing, locations and online booking. My own coaching runs on one.
Your work, large and fast, in a layout built around it.
Something else? Tell me about it and I’ll say honestly whether I’m the right fit.
Stay for a game
18 small games I built for fun, with leaderboards and a new Word every day.
- StackDrop each block on the last and build the tower as high as you can
- WordOne five-letter word a day, six guesses to find it
- RallyTennis against the computer, first to three games
Have something in mind?
Tell me what you’re building and I’ll write back with what it could look like.
