// FRONTEND ENGINEER
Ahmed Rayhan
Primadedas
Design systems built to hold — from a two-person startup to a national health ministry.
Engineer, builder, organizer
I build design systems that don’t break — whether the team is two people or the platform serves a country. Seven years doing that in React and Next.js, and teaching 1,800+ developers to do the same.
Frontend engineer with 7+ years specializing in React and Next.js, with a track record of building scalable systems from the ground up — from clean architecture and design systems to CI/CD pipelines that cut hosting costs by 71%. Most recently led frontend at a US-based edtech startup, managing a team across US–Indonesia timezones, while building national-scale healthcare systems for UNDP and Indonesia’s Ministry of Health. Beyond engineering, I contribute to the developer ecosystem through community organizing and regular technical speaking on frontend and Firebase topics.
Also a mentor at GoTo Impact Foundation and instructor at Skydu Academy.
This site runs on Prima UI — the design system I built from scratch. // PRIMA UI
