Crypto platform
A consumer crypto platform: wallet, swap, miner management, earning and an admin side. The web app was built twice: first in Blazor WebAssembly, later rewritten in React. I built both versions.
what I did
- Blazor WASM PWA: dozens of pages, API clients generated from the OpenAPI spec
- React rewrite: wallet, swap, transfers, on-chain purchases, administration
- Balances and rates in real time over SignalR
- Multilingual i18n with RTL support, bot protection
a technical detail
Both versions use the same API through typed contracts: the Blazor client generated from OpenAPI, the React side through a typed contract layer. That meant the rewrite only touched the UI, not the backend integrations.
Got something similar? Tell me what needs doing and how it works today.
