I'm Muhammad Fiqi Firmansyah — Qyu. Writing code since the 10th grade, now pursuing Informatics Engineering at Semarang State University, Indonesia. Fascinated by the architecture of massive codebases — the kind thousands of engineers shape over decades. I study how big tech builds systems that outlive their creators. When I'm not deep in a repository, I'm reading, watching films and anime, or tracking the latest in machine learning. Software engineering and ML aren't just fields I study — they're the craft I'm committed to mastering.
