Document history and audit trail
Submit sample documents as a customer, review them as staff, then advance time to see expiry reopen requirements.
Customer onboarding portal
Switch between customer and staff to manage documents, approvals, comments and expiry dates.
Opens onboarding.taiphamsolutions.com in a new tab. No account, no signup, and nothing you do in it leaves your browser.

Features
Seeded examples use English names. Switch between English and Vietnamese.
Simulated roles
Switch roles to explore workflow permissions. This is not secure authentication.
The flow it closes, end to end
Every step below happens inside the demo. There is no point in it where the work leaves the browser and comes back.

What is real, and what is not
There is no server behind any of this, which decides both columns. The left one is what that constraint made worth building properly. The right one is what it rules out.
Actually handled
- Document history and audit trail
- IndexedDB persistence
Deliberately not real
- No backend, real accounts or cross-device synchronization.
- Payments, tax and transfers are simulations. Do not use sensitive documents; local data is unencrypted and may be cleared by the browser.
How it is built
The write-up sells harder than the application does, so it is on the page rather than in a repository nobody can open.
- Frontend
- Preact + TypeScript
- Storage
- IndexedDB
- Hosting
- Cloudflare Workers
The services this is evidence for
A demo exists to prove something on the offer list rather than to be impressive on its own. These are the ones this one argues for.
The other demos
Each one is a different kind of problem, and all of them are in the Demos menu at the top of the page.
Want the version of this with your rules in it?
This one was built to a constraint nobody would choose. Yours would have a server, real accounts, and the parts of the domain that are actually hard. Tell us what the software has to do and we will tell you what it takes.
Bring the messy version of the problem. That is the conversation we enjoy most.
