🎯 Systems Analysis & Self-Taught Low-Level Enthusiast 📍 Pelotas-RS, Brazil
☕ Fueled by coffee, logic, Pink Floyd on my headphone, and Tolkien's universe.
My journey into software development was driven by a relentless curiosity to "pop the hood" and see how things work at the deepest level. Entirely self-taught, I've gone down the rabbit hole of C, C++, Reverse Engineering, and Cybersecurity, seeking the learning to interact directly with memory and the bare metal.
While I leverage Python to build modular architectures and AI frameworks, my primary focus and true passion lie in systems programming, binary analysis, and exploring hardware architecture.
I am currently pursuing an Associate Degree in Systems Analysis and Development at UniSenac, with long-term plans to pursue a Master's degree in Computer & Electronic Engineering. Drawing from my practical experience operating industrial machinery and SCADA systems, my deep dive into low-level execution and embedded development is driven purely by my own independent studies and hands-on experimentation.
My most ambitious projects right now involve writing a bare-metal Ring 0 interactive shell from scratch, developing robust C firmware for ESP32 microcontrollers, and building a local-first, multimodal AI framework.
- ⚙️ x86-RealShell: A bare-metal x86 real-mode interactive shell built from scratch in Assembly, exploring Ring 0 privileges, bootloaders, and hardware drivers.
- 🔌 Embedded Firmware: Building finite state machines and managing real-time tasks for the ESP32 using C and the ESP-IDF.
- 🔐 Reverse Engineering & Systems Programming: Diving deep into C/C++, binary analysis, and low-level execution for security and modding.
- 🤖 L.I.A. (Local Intelligent Assistant): Developing a modular, multimodal AI framework utilizing Python and the MCP protocol for local automation.
| Project | Stack | Description |
|---|---|---|
| x86-RealShell | Assembly x86 | A minimalist Ring 0 bare-metal shell with a custom 2-stage bootloader and hardware drivers. |
| Ghost Shell | C / C++ | Custom shell environment for low-level system exploration and execution. |
| L.I.A. Framework | Python / MCP | Personal AI assistant with semantic memory, screen vision, and dynamic plugins. |
| NativaStub Gen | C++20 / x64 | Automated Syscall stub generator that parses ntdll.dll to extract SSNs and bypass EDR hooks via Direct Syscalls. |
- 🔧 Mechanics: Tearing down and maintaining my Honda CG 150 Fan engine.
- 📖 Lore & Audiobooks: Always ready to learn more of Middle-Earth lore or get immersed in dramatized audiobooks.
- 🎮 Gaming: Co-op sessions, RPGs, and Souls-Likes, whenever the coffee permits some downtime.
- 🎧 Playlist: A chaotic but perfect focus mix of classic rock and psychedelic.
