I’m from Guarulhos, São Paulo, studying at a public high school and passionate about technology, mathematics, and building systems from scratch. I love exploring computer science in depth, learning new things every day, and spending my free time playing soccer and basketball. My dream is to study abroad, grow as a developer, and create projects that make a real difference in the world.

My name is Diego, and my journey in technology began when I was 10 years old, experimenting with Python and trying to understand how computers truly work beneath the surface. Over time, what started as curiosity became a defining part of my life. I enjoy studying complex topics such as mathematics, low-level programming, computer architecture, and artificial intelligence. I am a scholarship student in Prandiano, an advanced mathematics program focused on problem-solving and logical reasoning. This has helped strengthen my ability to think deeply, learn independently, and approach challenges with creativity and discipline.

Rosetta-6502 is my main personal project: a cycle-accurate virtual machine that emulates the classic MOS 6502 CPU architecture. The goal is to recreate the processor with full precision, including its instruction set, timing, memory interactions, interrupts, and hardware behavior. The name “Rosetta” is inspired by both the Rosetta Stone, a key artifact for language translation, and Apple’s Rosetta, which translates between PowerPC and ARM architectures. My project follows the same idea: translating and deeply understanding how computer architectures work. Rosetta-6502 is written in C, with some assembly routines for critical components. It aims to be a platform for studying computer architecture, experimenting with low-level systems, and running 6502 programs with accurate behavior. The CPU and clock systems are functional, and memory modules are actively being expanded.
