• In-house products and production LINE Mini Apps for enterprise clients, owned from requirements through architecture, release, and long-term maintenance.
• Developer platform work: extensibility layers that open components to source-level customization, with AI-assisted editing for non-engineers.
• Frontend architecture for multi-step consumer flows, integrated with LINE Platform services and third-party APIs, designed around their failure modes.
• Code review, debugging, and architecture support for junior engineers.
