Web3 & Ai Product Builder | React, Type Script & Python
I'm Jeauk Lee (SAPGUN), an independent Web3 and AI product builder based in Busan, South Korea. I turn ideas into working prototypes, with a focus on user control, safer onboarding, and practical tools.
PROJECTS: Vespera explores local-first AI agents, context ownership, human approval, and task recovery. TrustFi focuses on risk visibility before Web3 signatures and permissions. Swift Market is an XRPL-based P2P marketplace project. I also build Windows utilities including KeyGlow and SAPGUN Media Grabber.
STACK & APPROACH: React, Next.js, TypeScript, Python, and Tauri, with hands-on project experience in Solidity, XRPL, and Rust/Anchor. I use AI-assisted development while reviewing behavior, testing flows, and documenting limitations.
BACKGROUND: Sports Science at Pusan National University; AI and chatbot training at Digital Smart Busan Academy; marketing, CRM, and web work at Livart Jipterior Haeundae. I also connect local Web3 and AI builders through BUKMO in Busan.
LOOKING FOR: Remote opportunities with early-stage Web3 or AI teams in product development, full-stack implementation, wallet onboarding, developer tools, and technical documentation.
