One-Person AI Company · JandI
No more repetitive work.
A one-of-a-kind app, built just for you, takes over.
J&I (JandI) is a one-person company based in Yangpyeong, Korea. Founder Jey Park works as an “AI orchestra conductor,” directing a range of AI tools to build custom apps and websites — one client at a time — that remove the repetitive work small businesses and teams face. I don’t sell off-the-shelf templates; I come see how you actually work and build a tool made just for you.
Three things that matter
Built to fit, on site
No templates. I watch how you actually work, then design around it.
It becomes yours (BYOC)
The app, the data, the accounts — all owned by you. I’m the one who builds it for you.
Results, not hours
I’m paid for the value of the busywork that disappears.
From staff attendance apps to Toss-payment-integrated web apps — I build and run them myself.
A look at the work
“Can you build something like this?” Just ask.
