Protocol engineer focused on distributed systems, consensus, and P2P networking. I contribute to blockchain core infrastructure in Rust and Go - Lighthouse (Ethereum consensus client), Foundry, and Cosmos EVM - with merged PRs including peer penalties and error handling for Gloas P2P payload-envelope gossip (Lighthouse #8981) and interactive keystore-overwrite protection in `cast wallet new`(Foundry #13679), plus a benchmarked performance optimization to Cosmos EVM's GetAccount (#1203). Comfortable across Rust, Go, and C/C++, with a working knowledge of consensus protocols (LMD-GHOST, HotStuff, Narwhal, PBFT) and hands-on P2P/gossip experience. CS student at Chungnam National University; member of OraKle (KAIST blockchain club) and an active hackathon builder. Open to remote protocol/infrastructure roles — internship or contributor. Based in South Korea (KST).
