I develop embedded systems and functional hardware prototypes from firmware and hardware integration to LVGL interfaces and device-level testing. If you're building an IoT product, a connected device, or an embedded proof of concept, I can help turn your requirements into a working prototype. What I can help you build: Embedded firmware: ESP32, ESP32-S3/P4, STM32, Arduino, FreeRTOS, peripheral drivers, and hardware interfaces. IoT connectivity: MQTT, Wi-Fi, ESP-NOW, sensor integration, remote monitoring, and device communication. Embedded GUI: LVGL interfaces, touchscreen controls, display drivers, and responsive device UI. Hardware integration: Sensors, displays, storage, audio, communication modules, and power-aware embedded design. Functional prototypes: Component selection, firmware development, integration, testing, and optional 3D-printed enclosures. Engineering experience includes: Developing an ESP32-P4 multimedia player with MP3 audio and AVI/MJPEG video playback, including hardware-accelerated display processing. Building embedded touchscreen interfaces and device-control systems using LVGL. Developing sensor-based monitoring devices and connected embedded applications. I focus on practical engineering, maintainable firmware, and testing on real hardware—not just code that compiles. My approach: Understand your requirements, select the right hardware, develop the firmware and interface, integrate the components, and validate the prototype against agreed requirements. Whether you need help with an existing embedded project or want to develop a new proof of concept, let's discuss your requirements, constraints, and expected deliverables.
