The problem
Somebody with accounts at five banks has five logins, five dashboards and no single view of what they own. This application is that view: every balance, every transaction and every investment plan in one place, moving as the underlying accounts move.
What I did
I built the dashboard in React and TypeScript, starting with the live charts that are the first thing anyone looks at. Around them: linking and managing multiple accounts, reading balances, joining the investment plans each bank offers, and reading transaction history either consolidated across every account or one account at a time.
The typing mattered more here than on a typical project. A number on this screen is someone’s money, and a field that arrives as a string when a chart expects a number is not the kind of bug you want to discover in production.
Result
Six people building against one shared set of types, with the dashboard as the piece everyone touched.
