Developed core Rust Substrate modules (pallets) powering Chainflip’s cross-chain AMM, validator set management, state commitments, and swap routing logic. Implemented threshold signature (TSS) workflows, ensuring secure cross-chain custody and transaction execution across EVM chains. Built high-performance, low-latency Rust services for event watchers, block processors, swap execution engines, and bridge relayer infrastructure. Designed and implemented cross-chain messaging components, leveraging light clients, relayers, and off-chain workers for secure state synchronization. Contributed to Chainflip’s decentralized P2P network by developing networking layers, peer discovery logic, gossip protocols, and validation flows. Integrated Kafka and async processing systems for indexing, settlement batching, and bridging workflows. Developed testing harnesses for cross-chain operations, including simulation environments for adversarial conditions, network partitions, and chain reorgs. Implemented monitoring, telemetry, and internal alert frameworks using Prometheus, Grafana, and structured logging for validator operations and bridge health.

Engineered and maintained Solidity smart contracts powering USDe issuance, collateral management, and delta-neutral hedging mechanisms. Built automated risk management and hedging systems integrating with CEX/DEX venues using Rust, TypeScript, and Python, improving execution efficiency and reducing slippage. Improved oracle aggregation and price-feed reliability by implementing multi-source failover logic using Chainlink, Pyth, and custom TWAP systems. Optimized the internal CI/CD pipeline for contract deployments and simulations, improving deployment speed and reducing operational overhead. Contributed to design and execution of stress tests, load simulations, and liquidation backtesting, identifying performance bottlenecks and improving protocol robustness. Created internal DSL tooling to accelerate scenario modeling, risk parameter changes, and hedging configuration updates. Implemented high-throughput off-chain services to support real-time funding rate monitoring, perpetual market exposure tracking, and delta rebalancing strategies. Led code review best practices, audit preparation, and internal knowledge-sharing sessions improving overall engineering velocity. Built secure, scalable backend APIs (Go/Rust) for internal teams, exchanges, and partners to interact with issuance, redemption, and hedging workflows.

Designed and implemented Solidity smart contracts powering Swell’s LSDfi ecosystem, including vaults, staking modules, reward distribution, and bonding curves. Optimized EVM gas consumption across core contracts, reducing operational costs and improving execution reliability under high network load. Built secure restaking adapters and integrations with external protocols (EigenLayer, LST ecosystems), ensuring compatibility and safety across all execution paths. Developed internal Rust-based off-chain services for validator orchestration, MEV extraction, reward distribution, and slashing protection. Led performance tuning and debugging of staking flows using Foundry, Tenderly, Hardhat, and your custom simulation frameworks. Implemented a dynamic role-based authorization framework, enabling governance to adjust protocol parameters without redeployments. Built asynchronous data pipelines for state tracking, APR calculations, and validator metrics using TypeScript, Rust, and GraphQL indexers. Collaborated with security auditors to remediate vulnerabilities, performing internal fuzzing, invariant testing, and formal verification. Designed dashboards and admin tools integrating The Graph, Dune queries, and custom RPC services for real-time protocol insight.
