    Worked as a Full Stack and IoT Developer in a company focused on connected devices and custom IoT solutions.

    My role combined embedded firmware development with the creation of web platforms and dashboards used to monitor, configure and manage IoT devices in real time.

    On the embedded side, I developed firmware in C++ for ESP32-based devices using the ESP-IDF framework. This included:

    Device communication and networking
    Wi-Fi and connectivity management
    Sensor integration
    Real-time data handling
    Device configuration systems
    OTA update systems
    Performance optimization and debugging
    Low-level hardware interaction

    On the web development side, I designed and developed internal dashboards and management platforms using HTML, CSS and JavaScript. These tools allowed users and technicians to:

    Monitor device status and telemetry
    Configure remote devices
    Visualize real-time data
    Manage deployments and updates
    Control connected systems through intuitive interfaces

    I also worked with SQLite databases for local data storage, configuration management and data persistence, ensuring reliable synchronization between devices and management platforms.

    This experience gave me a strong understanding of the full IoT development lifecycle, from low-level firmware and hardware communication to backend logic, databases and user-facing web applications. It also helped me develop a practical approach focused on reliability, maintainability and scalable system architecture.
