About Me

Portrait of Muhammad Hibrizi Farghana (Izi)

I am Muhammad Hibrizi Farghana — most people just call me Izi. I am an Information Systems undergraduate at Universitas Indonesia (GPA 3.79/4.00) with hands-on experience in backend, mobile, and AI-integrated application development using Flutter, Django, Spring Boot, and FastAPI. I enjoy building scalable backend systems, wiring up external services and APIs, and shipping apps powered by LLMs and real-time AI. Outside of code, I love teaching, mentoring, and watching anime.
