Reza Mauliadi

I’m a Senior Frontend Engineer with 10+ years of experience building and scaling complex web platforms using TypeScript, React, and Next.js.

My work focuses on frontend architecture, design systems, and performance optimization across multi-product environments. I’ve led initiatives such as building shared UI platforms, migrating large codebases, and improving developer experience and delivery pipelines in monorepo setups.

Previously, I worked as an Engineering Manager at Flip, where I scaled the Flip for Business product (10k+ MAU, billions IDR in monthly transactions), grew and mentored engineering teams, and led major improvements in system performance, delivery execution, and frontend performance.

I enjoy working at the intersection of product, design, and engineering, translating complex business problems into scalable, maintainable frontend systems.
