What I'm looking for

I hope to use the skills I have learned to work, get better treatment and recognition.

I've built responsive, API-driven e-commerce experiences through DoraHandmade, where I developed product-detail pages and reusable React components for a five-person cross-functional team.

I integrate RESTful APIs, handle loading, error, and empty states, and build full-stack practice applications with Node.js, Express, SQLite, JWT, ECPay, and automated testing. My recent work includes role-based authorization, admin CRUD flows, inventory validation, and payment-result verification.

Before frontend development, I spent six years validating and auditing high-volume tax data. That experience sharpened my attention to data integrity, exception handling, cross-team communication, and practical process improvement.
