Hello World

Hi 👋, I'm João Victor! A versatile **Software Engineer** with experience in both **backend/cloud/AI development** and **embedded systems and electronic product development**.

• 🎓 I hold a double degree in Science and Information Engineering (UFABC), and a technical certification in Mechatronics (SENAI).

• 🚀 I work on scalable backend development using Python (FastAPI), AWS cloud integrations, RAG/LLM pipelines, and real-time monitoring systems for corporate and industrial environments.

• 🧑‍💻 I also have over 7 years of hands-on experience in embedded firmware development, industrial communication protocols (BLE, MQTT, Modbus), PCB design (Altium), and embedded graphical user interfaces.

• 🌍 I’ve worked on international AI projects, hackathons, workshops, and electronic product development from prototypes to manufacturing.

👨‍💻 More about me

• 🛠 With over 7 years of experience, I've worked on projects for companies like Siemens Energy, Gerdau, Natura, and Metso. My role spanned developing Software, device drivers,machine learning ,GUIs, and Bluetooth communication protocols.

• 💻 My core programming skills include C, Python, Java, and Qt for cross-platform embedded GUIs and desktop tools. I'm also experienced in Linux-based development environments for embedded platforms such as Raspberry Pi and BeagleBone.

• 📡 I develop firmware using microcontrollers like STM32, Nordic, ESP32, and integrate them with custom hardware, low-energy protocols, and sensors.

• ⚙️ I actively contribute to the electronic product lifecycle: PCB schematic design, layout (Altium), firmware, user interface, and manufacturing using pick-and-place machines.

• 🔬 I have hands-on experience with signal processing, embedded ML, and industrial-grade sensors (temperature, vibration, acoustic).

• ⚡ Outside of work, I enjoy learning new technologies, tackling tough bugs, and turning ideas into real, functional products.
