Experience
SMARTCONTRACT ENGiNEER
OraichainLab 2024 - 2025
Participated in the core chain development of the OraiBTC subnet—a subnet bridge connecting the Bitcoin network and Oraichain. Contributed to research on light client verification of Bitcoin block headers, and supported debugging and resolution of application hash mismatches during production testing. Additionally developed the LCD (Light Client Daemon) module to enable frontend-side data querying from the OraiBTC chain. Engineered a second-generation OraiBTC bridge by refactoring the design into a native CosmWasm-based module on the Oraichain mainnet. Took ownership of smart contract logic such as light client implementation for verifying blocks on Bitcoin, off-chain relayer services for orchestrators, and frontend interaction layers. Designed and implemented smart contracts on the TON blockchain using Func language, enabling a decentralized, trust-minimized asset bridge via following IBC protocol. Participated in cross-chain security and consensus flow review. Developed a message relay system between Solana and Oraichain for a centralized bridge prototype, focusing on high-throughput relaying and transaction integrity in asynchronous environments. Built a Perpetual Whales MCP that aggregates and profiles historical trading behavior and portfolio statistics of whales on-chain. Outputs were integrated into a LLM to generate trading reports based on whales analytics. Currently developing AI agents within an AI agentic platform, leveraging Google’s A2A protocol for inter-agent communication. My work focuses on REWOO agents that are used to optimize for task parallelism and token efficiency. Contributed pull requests to Microsoft’s open-source Autogen framework, improving compatibility with the Magnetic One agent during the integration of MCP result processing.
