I build software across the stack — from hardware emulation to cloud applications.
I'm a Brazilian developer interested in emulation, Android, graphics drivers, and the systems behind everyday software. I enjoy following a problem through the stack: an instruction that behaves incorrectly, a rendering issue, a failing build, or an API that needs a better design.
My work spans C, C++, Kotlin, and Java, alongside web development with Laravel, typescript and Linux infrastructure. I also have experience modernizing Java and PHP applications, building integrations, and automating repetitive work.
A Game Boy emulator written in C99 with SDL3, built to explore how the hardware works by implementing it.
- SM83 CPU, memory bus, scanline PPU, timers, interrupts, and joypad input.
- Basic MBC1, MBC3, and MBC5 cartridge banking.
- Boots and runs some DMG ROMs, including Tetris; accuracy is still a work in progress.

Temporary file sharing with expiration, optional passwords, and download limits.
- Java 26 Lambda handlers with API Gateway, S3, and DynamoDB.
- Direct browser-to-S3 transfers through presigned URLs.
- React and TypeScript frontend, Terraform infrastructure, and local AWS emulation with Floci.

My open-source interests center on Android, graphics, and emulation, including contributions to the Mesa/Turnip ecosystem and the Eden emulator. My repositories bring together original projects, experiments, and forks used to investigate and adapt existing software.
I'm always interested in conversations about emulator internals, Linux, Android, rendering, and useful tools. Reach me on Telegram or LinkedIn.
Curious enough to dig deeper. Persistent enough to keep going. Purple by choice.
