Muhammad Arfandy Surya Nugraha

A fullstack developer with 4+ years building web and mobile applications. I've shipped Flutter apps, React frontends, and Golang, PHP & Laravel backends — spanning edtech, digital-signature, and social-investing platforms.

Lately I've been deep in Golang services and AI systems — RAG chat and an AI CV-scoring pipeline. I love a hard challenge, and seeing what I build genuinely help people at scale.
