About Me

Raditya Fauzan

Raditya Fauzan

AI · ML Engineer · Mathematics @ UI

I am a final-year Mathematics student at Universitas Indonesia with a deep focus on AI and Software Engineering. Mathematics, for me, is not just about formulas — it is the language of logic and precision that underpins every intelligent system I build.

I thrive at the intersection of clean code and smart algorithms. Whether architecting a RAG-powered chatbot, building a real-time computer vision pipeline, or optimizing a backend with FastAPI and Celery, my goal is always the same: make AI work reliably in the real world — backed by solid mathematical intuition.
