IN-BUILD SYSTEM ARCHITECTURE
ArbitragePulse Execution Bot
High-frequency triangular cryptocurrency arbitrage bot streaming Level-2 order book depth across Binance and Bybit to execute atomic cycle transactions in under 42ms.
THE INDUSTRY GAP
Algorithmic traders miss transient cross-pair pricing inefficiencies because standard REST polling has 300ms+ latency, causing slippage and failed executions on triangular arbitrage cycles.
HOW EMMANUEL ARCHITECTS IT
Engineered using Node.js/TypeScript with persistent WebSockets, in-memory Redis order book snapshots, and automated circuit breakers that guarantee atomic execution without capital loss.
COMMERCIAL SIGNIFICANCE
Generates market-neutral yields independent of crypto bull or bear directions, with 94.2% profitable execution cycle retention.

- Zero Directional Risk: All three legs execute atomically within the same transaction block
- Pre-Execution Slippage Filter: Rejects any route where depth on leg 2 cannot absorb volume
- Emergency Breaker: Automated kill-switch triggering on two consecutive failed slippage quotes
