VNFData
The financial data platform of VietnamFinance magazine
- Web
Index data for four exchanges, listed-company profiles and a ratings system, updated through the trading session. The hard part is not the charts but keeping the numbers honest: splits, dividends, renamed tickers, holiday sessions. Miss one and the whole price line is wrong.

The data pipeline
Prices arrive live and pass through cleaning and reconciliation before they reach the database. The API is written in Go and sits on a private host with no route from the internet; two Next.js applications — the public site and the CMS — talk to it over the internal network. Redis holds the hot data during trading hours so the site does not go back to the database every time someone opens a chart.
