Founding-stage protocol engineer for Mitosis. Designed the LRT vault system (factory + beacon proxy, deterministic deployment), attracting up to $100M in initial liquidity; contributed the Lista CDP integration and earn manager for the launch campaign; and worked through external smart contract audit review. Designed core protocol components for the Mitosis L1 execution layer, including validator staking, reward settlement, VLF vault, and hub-chain protocols.

Primary author of Hyperlane's official CosmWasm implementation, covering multisig ISM signature verification and warp-route token bridging for CosmWasm environments. Supported the external audit review process.

Built and operated high-availability Hyperlane validator infrastructure across 125+ chains on Kubernetes with ArgoCD GitOps and Prometheus/Grafana observability. Reduced external RPC dependency by 28% (97k → 70k daily calls) through request batching and caching.

Sole engineer for the alpha version of a price range prediction market protocol. Built an event-sourced execution engine with modular STFs, parallel execution by aggregate access, and RocksDB + JMT versioned state. Developed an oracle service for real-time CEX WebSocket feeds (later migrated to Stork) and a TypeScript SDK abstracting the Borsh wire format for integrations.

Led development of eth-anchor, the Ethereum bridge layer for Anchor Protocol ($16B+ peak TVL). Implemented proxy upgradeability pattern and non-atomic init-finish flow for cross-chain delay handling.

Proposed and led Pylon Protocol 0→1 as an internal incubation — a yield redirection platform on Terra. Architected core CosmWasm contracts in Rust from the ground up, reaching $200M+ peak TVL, and took the contracts through audit and production deployment.

Designed Ethereum-side incentivized LP contracts for Mirror Protocol ($100M+ in assets) from scratch — initially contributing before formally joining TFL. Managed end-to-end audit and production deployment.

Developed and tested Solidity smart contracts for a decentralized data trading protocol, achieving 100% branch coverage. Built Go and Python SDKs, contributing to an architecture transition from a LibP2P/gRPC P2P node to a lightweight protocol SDK. Developed a Go-based worker service for daily on-chain synchronization of consent records with Klaytn Fee Payer proxy injection.

Built a real-time and batch data pipeline for enterprise consortium partners. Managed Terraform infrastructure and migrated from Serverless/AWS Lambda to Kubernetes (Argo Events + Argo Workflows) on AWS EKS with FluxCD GitOps.
