About

I'm FA Chalik, a frontend-focused fullstack developer based in South Jakarta with 5+ years of professional experience. I'm currently the sole frontend engineer across three AI products — Knowledge Chat, Intelligent Document Processing and Credit Scoring — owning the UI architecture, the shared design system and the observability setup. Part-time, I build the frontend for Medira, an AI hiring platform. Before that I spent three years at Infomedia Nusantara (Telkom Indonesia group) building enterprise web apps.

My core is React, Next.js and TypeScript, and I work across the stack with Node.js, NestJS, PostgreSQL and Docker when a feature needs it. I also published an IEEE paper on CNN image classification, so I'm comfortable working alongside ML and data teams.
