Software Engineer / AI & ML
About
I'm Arya, a software engineer based in Indonesia. Most of my work sits where machine learning meets ordinary product engineering — LLM pipelines, retrieval, and NLP systems that have to survive real inputs.
Outside that, I build web and mobile applications, run a small home server on hardware that was headed for a drawer, and write about both.
This site keeps three kinds of writing apart: Projects are things I shipped, Build Notes explain how something was approached, and the Readingis everything that isn't about code.
