Designed and shipped a production-grade HFT flash loan arbitrage bot for Base, architected as a hybrid system - a Node.js/TypeScript orchestration layer paired with a Rust hot path for maximum execution speed. The Rust engine ingests WSS events in real time, maintains world state, and runs pool-search on touched liquidity pools; once an opportunity is detected, it builds the full calldata and hands it off to the TypeScript layer for on-chain submission. Opportunity discovery uses a cascading filter pipeline: an initial spread-based screen, followed by a golden-section search prefilter to narrow the profitable price range, then a ternary search with full off-chain tick-math simulation - splitting the range into 10 segments between a configurable minimum flash-loan size and the maximum available liquidity on the thinnest leg. Pre-ternary filtering runs in ~0.01ms per route, with full ternary simulation at ~0.5-0.8ms per route depending on route complexity (V2-V3/V2-V2 vs V3-V3). On-chain, the smart contract enforces independent safety guards - liquidity checks, on-chain math validates liquidity, and balance-after-greater-than-balance-before validation - as a final execution safeguard. Built to support major Base DEX ecosystems (V2/V3 forks, Aerodrome Slipstream with dynamic fees, and others), with an architecture designed for straightforward portability to other EVM chains.

Also developed and deployed a fully autonomous execution bot for Polymarket - running multiple WSS channels (including the user channel) for real-time state awareness, with built-in capital-protection logic and a GTC execution strategy engineered to mimic human-like trading behavior, alongside a dedicated negRisk strategy module.
