Rizky Agung Prasetyo

Next.js Full Stack Developer | AI Enthusiast

Based in Yogyakarta, Indonesia.

Profile Summary

I'm an independent full-stack developer with a strong passion for modern web technologies. I specialize in building interactive experiences using GSAP animations, and my core stack revolves around Node.js, TypeScript, and Next.js. Driven by curiosity, I continuously explore new technologies, especially in AI, AI Workflow, AI Agents, and Large Language Models (LLMs).

I'm the creator of Maven AI, an open-source, AI-powered tool designed to simplify electronics product research and help users make data-driven purchase decisions. To challenge myself and replace the original Maven AI landing page, I rebuilt the award-winning Flow Studio website (a Site of the Day on Awwwards) from scratch using Next.js and GSAP.
