I’m Harper Liu, a software engineer with 4 years of experience building web applications and production-grade frontend features for large-scale e-commerce and operations platforms. I enjoy turning complex business requirements into fast, reliable user experiences—whether it’s building high-traffic promotion pages or improving platform workflows through better monitoring, standardization, and performance-focused engineering. Across my roles, I’ve worked with modern TypeScript/JavaScript and React, plus APIs and GraphQL, and I’m comfortable collaborating across teams to reduce error rates, improve delivery efficiency, and lower development cost. I also like using LLM-based automation to support operations work—such as generating standardized question/verification content and creating prompt debugging tools—while leading projects from architecture decisions to browser-based tooling and secure workflows.…I’m Harper Liu, a software engineer with 4 years of experience building web applications and production-grade frontend features for large-scale e-commerce and operations platforms.
