Zebitex
Exchange & market-data infrastructure
Zebitex is a French centralised crypto exchange, built in Toulouse, matching euros against major cryptocurrencies. I built exchange and market-data infrastructure for it: standardised APIs, real-time order flow and trading agents, and the correctness and uptime guarantees that live financial markets demand. A dropped message or a mispriced book is not a bug report but lost money.
- Standardised exchange & market-data APIs
- Real-time order flow and trading agents
- Correctness and uptime for live financial markets
