Architected and shipped a cross-chain bridge on top of Axelar and LayerZero, handling everything from the contract layer to the off-chain relayer that keeps messages flowing reliably across chains. Wrote the relayer service in Rust, covering message signing, nonce management, and retry logic with backoff, the kind of detail that matters when a bridge goes down under load. Developed 150+ smart contracts in Solidity and Move (SUI) spanning LendingPool core logic, variable/stable rate models, health-factor liquidation, oracle integrations, flash loan modules, aToken/debtToken accounting, and cross-chain bridges optimized through storage layout restructuring, calldata efficiency patterns, and redundant state-read elimination. Built an agentic Claude-powered audit pipeline with structured prompt chains, MCP server integrations, and automated checklists that systematically review Solidity contracts for reentrancy, access control flaws, oracle manipulation, arithmetic overflows, and DeFi-specific attack vectors replacing manual review cycles with repeatable, automated security workflows. Integrated multiple decentralized oracle networks for on-chain price feeds and built the off-chain aggregation layer in Rust that validates incoming data, catches outliers, and falls back gracefully when a source goes stale. Designed and deployed real-time on-chain event indexers in Go ingesting millions of daily transactions via RPC/WebSocket streams, persisting to structured stores, and serving sub-second query latency for trading dashboards and protocol monitoring. Architected and developed CI/CD pipelines with automated deployment scripts in typeScript and GoLang enforcing mainnet fork testing, integration suites, and end-to-end coverage across every release cycle. Integrated Hexagate(python) and Tenderly(typescript) actions to automate protocol security, triggering instant pauses and parameter adjustments upon detection of on-chain anomalies or exploits. Built an Claude-powered automated liquidation Agentic engine that monitors collateral health across deployed EVM chains, triggering cross-chain liquidations the moment thresholds are breached.

Developed order matching and RFQ engines with in-memory position management processing high-throughput trade flows at sub-millisecond latency, backed by persistent storage for crash recovery and auditability across 20k+ daily transactions. Built a Rust liquidation bot for an Aave V2 fork that monitors health factors across all positions, triggers liquidations on threshold breach, and dynamically adjusts gas pricing to maintain profitability across multiple monitored positions. Instrumented production infra with Prometheus, Grafana, and structured logging enabling real-time alerting on liquidation bot health, indexer lag, and relayer throughput, cutting incident response time by 30%. Integrated PancakeSwap smart contracts directly into the protocol for collateral and loan token swaps during borrow and repayment flows, removing friction for users and reducing the number of transactions needed per operation. Researched and benchmarked liquidity mechanisms including dAMM, SLAMM, VAMM, and Delta Algorithm, with findings directly shaping the architecture of Khalani's Interchain Liquidity Hub and a CDP-based omnichain stablecoin. Collaborated with product and design to streamline on-chain/off-chain interaction flows cutting redundant transactions and reducing UX friction while conducting rigorous code reviews and mainnet fork tests on Foundry and Hardhat to surface edge cases before production deployment.

Architected an AMM protocol from scratch covering liquidity pool logic, swap routing, and fee distribution, integrating Chainlink oracles and a Go-based price validation service that cut stale-data errors by 60% before collateral calculations. Built a React, Next.js trading UI with real-time pool stats, liquidity position tracking, wallet connect, and swap routing, serving 10k+ MAUs with sub-20ms sync latency via Ethers.js and WebSocket subscriptions. Developed a Node.js backend for API aggregation, background event processing, and price feed normalization, containerized with Docker. Wrote and audited ERC-20, ERC-721, and ERC-1155 token contracts and staking contracts with time-locked rewards, slashing conditions, and dynamic APY, deployed behind Transparent and UUPS proxy patterns for zero-downtime upgrades. Ran automated security audits across all Solidity contracts using Slither and Mythril, identifying and remediating 10+ high/medium severity findings before mainnet deployment across the AMM and staking codebase.
