Hi, I'm Gabriel Duarte Guerra

Full Stack & Security Engineer — Brazil. I build production web platforms by day and tear things apart at the firmware / kernel level by night. Computer Science student, long-time Linux user, and contracted vulnerability researcher.

🧠  What I actually do

  • Full stack engineering — shipping production web platforms, real-time systems, and enterprise integrations across modern JS and backend stacks.
  • Offensive security research & responsible disclosure — auditing software for vulnerabilities and reporting them through coordinated disclosure.
  • Reverse engineering at hardware & firmware level — tearing apart binaries, proprietary device protocols, and low-level anti-tamper/DRM stacks.
  • Low-level & systems work — C/C++, Rust, and Assembly on Linux, kernel internals, and embedded targets.

❤️  Tech

  • Languages — Rust · C / C++ · Go · Python · TypeScript / JavaScript · Assembly · C# · Java · PHP · Bash
  • Web / Backend — React · Angular · Vue · Next.js · Node.js · Bun · PostgreSQL · MySQL · MSSQL · MongoDB · Supabase · Firebase
  • Cloud / Infra — Google Cloud (BigQuery, Secret Manager) · Docker · Kubernetes · Nginx · Minio
  • Security & RE — IDA Pro (+ processor module dev) · x64dbg · GDB · Valgrind · APK Tool · JadX · BYOVD / UEFI / hypervisor analysis · JWT / OAuth auditing · multi-tenant isolation · GraphQL security
  • Embedded / Low-Level — Linux kernel internals · USB HID · BLE · Modbus TCP/IP · Arduino · Microcontroller & SoC firmware
  • Linux — Arch (daily driver) · Debian · Ubuntu · Kali · Fedora · NeoVim · shell scripting
