Message

At PT Fanintek, I served as the primary frontend developer for PT KAI’s Integrated Talent Management System, building most of the application with React, TypeScript, and Vite. I also developed InternHub from an empty project through production release as its sole frontend developer, creating a CMS and a portal for internship applicants.

I’ve modernized legacy applications, including migrating E-OS from Laravel to Next.js and TypeScript, and continued development of PT KAI’s public information portal. In freelance projects, I developed a live tracking application and a company profile website; I also built OddlyRinaldi, a website template studio with interactive templates and an offline-first Flutter app.
