The page rewrites itself for the person reading it, the same way the interfaces I build do.
Frontend engineer with 3+ years of experience building school ERP systems and booking platforms with React, Next.js and TypeScript. I currently lead the frontend of a 5-module ERP at Future Gate High School, and I built the booking platform used by 5,000+ students at Universiti Kebangsaan Malaysia.
Lubuklinggau, Indonesia. Open to remote work and relocation.
Most of my work is role-based UI: the same data, shown differently to each role. At the school that means admissions, HR, finance and inventory screens that share state across 20+ REST APIs. At Chup Online it was a responsive booking flow with online payment.
