Frontend Engineer building streaming Agent Chat / Workflow UIs with Next.js + TypeScript.
I specialize in event-driven runtime modeling, shared adapter layers, and production-grade reliability (cancel/retry/error recovery).

• Streaming / realtime events → deterministic UI state (messages · widgets · thread)
• Conversation consistency: regeneration/deletion boundaries & multi-item thread modeling
• Reliability: cancel / retry / error recovery + state synchronization
• Complex admin systems: hierarchical domain + search/filter + query-state sync
• Operational readiness: observability + CI quality gates to prevent regressions

• Built a Shared Agent Runtime Adapter used by both products to avoid duplicated runtime logic.
• Integrated an SSE-based agent runtime into UI, mapping async events into messages/widgets/thread state.
• Established consistency conventions for event ordering and conversation boundaries.
• Designed cancel/retry/error recovery flows with observability hooks.

• Developed an ad platform admin (Campaign → Ad Group → Creative) with Next.js 15 + TS.
• Standardized fetching & forms with TanStack Query v5 + Zod + React Hook Form.
• Implemented realtime 1:1 DM with Sendbird, stabilizing message state synchronization.
• Improved production stability with Sentry and CI quality policies (e.g., Sonar gate).

• Led an online video learning web product FE (Agora based).
• Built a React Native learning app with Firestore for content and user-state management.
