About
I am a Software Engineer with 7+ years of experience building scalable, high-performance web applications in JavaScript, TypeScript, React, and Vue, specializing in user-centric interfaces and global product expansion across international e-commerce platforms like TikTok Shop and Tokopedia.
Beyond writing code, I take a systems-thinking approach to how engineering teams operate. I build AI-driven tooling, agent workflows, and MCP servers that turn fragmented processes into structured, repeatable systems for myself and my teams.
