Hi, I'm Bruno Marsola 👋

Embedded Systems & OT Security | São Paulo, Brazil 🇧🇷

Transitioning from IT operations into industrial embedded systems and OT cybersecurity. Currently building firmware projects in C/C++ and studying industrial networking and ICS security.

🔧 What I'm working on

  • 🌡️ Embedded temperature monitor — DHT22 driver in pure C, I²C via ATmega328P registers, hysteresis alarm logic
  • 🔌 UART protocol tester — custom serial framing with CRC8, automated test suite in Python/pytest
  • 🔲 FPGA FSM in VHDL — finite state machine described, synthesized and simulated in ModelSim
  • 📦 Embedded datalogger — multi-sensor acquisition, FatFS SD card, Python dashboard

🛠️ Tech stack

Embedded     │ C / C++  •  VHDL  •  Arduino / ATmega328P  •  FPGA (learning)
Scripting    │ Python  •  Shell Script  •  Ansible
Networks     │ TCP/IP  •  VPN  •  Firewalls  •  Industrial Protocols (in training)
Tools        │ Git  •  Linux  •  Zabbix  •  Grafana  •  SIEM (Wazuh)
