โธ HI THERE!
Hey there! I'm Rizal, an Information Systems student and software developer who loves building cool, functional things.
My playground ranges from mobile development with Kotlin and Flutter to crafting solid web apps using Next.js and various backend tech. I'm all about that modern coding vibeโteaming up with AI as my daily pair-programming buddy to write cleaner code, explore new stacks, and build things a lot faster.
Lately, I've been spending my time diving into new tech trends and sharing my knowledge as a Mobile Dev mentor at GDG on Campus. When I'm away from the terminal, you can probably find me catching an F1 race (Forza Ferrari!) or hunting for a good cup of local coffee.
Always up for a chat about code, AI, or exciting new projectsโlet's build something awesome together!
