Engineering evidence
The books of a real travel agency, migrated and reconciled. Every figure below is measured on the systems themselves, and each one is shown its working on the project page it came from.
See how the ledger was builtThree systems, and what each one had to get right
The VAT ledger is the one a travel agency keeps its books on, and files its invoices from, and there is a walkthrough to play. Under it, Travora, where the hard part was making a correct record cheap enough to bother entering, and NiryatHub, which takes a Nepali producer from a spoken sentence to a filed invoice.

LiveEvery invoice filed as it is issued, and none of them editable afterwards
Double-entry VAT accounting for Nepali ticketing agencies. Every sales invoice is filed with the tax office as it is issued, an issued invoice can never be edited afterwards, and one deployment serves every client, isolated by PostgreSQL row-level security.
The stack
No aspirational logos. Everything here appears in something I have shipped, and most of it in something running in production right now.

LiveTrip budgets that survive contact with a real trip
A seventh-semester travel expense app. Every trip is a budget, receipts are photographed instead of typed, and each user's data is fenced off by row-level security rather than by a filter in the front end.

LiveNepal does not have an export-product problem. It has an export-access problem.
A hackathon prototype that takes a Nepali producer from one spoken sentence to a filed invoice, scoring ten destination markets, matching importers, assembling the compliance checklist, costing the corridor out of a landlocked country, and raising the invoice.
