👋 Hi, I'm Junior Gonzalez

Computer Engineering student with a focus on cybersecurity | Graduating Dec 2026

I build security-focused systems across software and hardware, with experience in Python development, embedded systems, and defensive security concepts. My interests span cybersecurity engineering, embedded / hardware security, threat analysis, and secure system design.


🧩 Interests

  • Cybersecurity and secure systems engineering
  • Embedded systems and firmware development (STM32)
  • Security tooling and automation in Python
  • System-level programming and low-level analysis
  • Reverse Engineering / Forensics
  • Defensive security research

🧠 Skills / Tools

Languages: C, C++, Python, Bash, (Learning Rust)

Development Boards: STM32, NXP FRDM-K64F, Raspberry Pi

Embedded Tools: STM32CubeIDE, Keil µVision, Zephyr RTOS

Hardware Communication Protocols: UART, SPI, I²C

Networking: HTTP/S, MQTT, TCP/IP Stack, OSI Model

Security Concepts: Secure Boot, Cryptography (SHA/AES), Hashing, Threat Modeling, Firmware Tampering

Tooling: Git, Linux, Kali, Docker, Wireshark, GDB, Ghidra


🧪 Featured Projects

  • Secure STM32 Bootloader – Firmware integrity verification and secure boot process
  • Security Automation Toolkit – Python-based tooling for analysis and data extraction
  • Embedded Signal Logger & Visualizer – Hardware data capture with Python visualization
  • Side-Channel Analysis (Exploratory) – Researching power analysis concepts on embedded devices

What I Value

  • Clear documentation and reproducible work
  • Understanding systems from the hardware up
  • Building tools that improve security visibility
  • Learning through hands-on experimentation

🌱 Current Focus

  • Deepening knowledge in secure firmware design and embedded / hardware security
  • Explore RF hacking
  • Preparing for contributions to open-source repositories
