Blockchain Developer @ Oraichain Labs

About

I’m a Blockchain Developer with 2+ years of hands-on experience building real-world Web3 products and blockchain infrastructure. I’m deeply interested in how decentralized systems work under the hood and enjoy turning complex protocol ideas into production-ready solutions. At Oraichain, I’ve had the opportunity to develop and maintain Oraichain mainnet and multiple application-specific sub-chains (including LFG-chain, Viexchain...), build smart contracts across Cosmos, EVM, and Solana ecosystems, and design backend systems that power Web3 applications. Technically, I work daily with Cosmos-SDK, IBC, CosmWasm (Rust), Solidity (EVM), Solana programs (Anchor, Rust), Golang, and Web3 backend stacks (TypeScript, JavaScript,...), with a strong focus on performance, security, and long-term maintainability. I’m currently looking for Blockchain Engineer / Protocol Developer opportunities where I can continue to grow, challenge myself, and contribute to building robust decentralized systems. I genuinely enjoy connecting with people who share the same curiosity and passion for exploring new blockchain technologies and next-generation Web3 infrastructure.
