At Ramzinex (Crypto Exchange), I led the engineering team responsible for developing a scalable, containerized market-making software that provided liquidity across more than 300 trading pairs. The system was designed in modular components, each running in a separate container, allowing for flexibility and scalability. This architecture enabled rapid detection of price changes and quick settlement to optimize profitability.We ensured predictable and controlled net daily profits by creating advanced monitoring panels to identify unprofitable pairs, often due to parameters like small spreads. I also implemented precise mechanisms to detect losses, trigger alerts, and automatically deactivate pairs for manual intervention when necessary.Additionally, I structured log collection from each container, enabling detailed monitoring of each pair's activity across different modules, significantly improving troubleshooting and system transparency.
