Manual Restarts
- Engineered a modular, delta-neutral trading monolith in Rust for cross-exchange arbitrage, achieving 336.5 hours (14 days) of continuous production uptime with zero manual interventions.
- Designed a 'Fast Lane' execution loop using Tokio, non-blocking async WebSocket streams, and try_send channels to ingest and process high-throughput market data with sub-millisecond core processing latency.
- Implemented pre-calculated state-machine logic that optimizes CPU compute by recomputing arbitrage spreads strictly for symbols with active order book updates.
- Developed a 'Slow Lane' automated risk management task that continuously calculates inventory delta across exchanges and executes automated futures short hedging loops to guarantee market-direction protection.
- Enforced strict 'Safety Gates' at the architectural level, preventing spot acquisition if corresponding futures markets lacked sufficient liquidity parameters.
- Built an idempotent order-matching pipeline that simultaneously fired dual execution orders, tracked real-time slippage, and handled complex balance validation.
