Truong P.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Jul 17, 2026.

Hi, I’m a seasoned Embedded Software Engineer with 10+ years of experience building reliable, scalable, and efficient firmware for microcontroller-based systems. My expertise spans from rapid prototyping to production-ready embedded solutions in IoT, automation, and control systems. I specialize in developing smart, connected devices that integrate modern technologies—from real-time operating systems (RTOS) to edge AI and secure cloud connectivity. Whether you're working on a new product prototype, need help with real-time motor control, or want to bring AI to your embedded device, I’m here to make it happen. My key areas of expertise include: -Embedded C/C++ for STM32, ESP32, AVR, ARM Cortex-M -Real-Time Operating Systems (FreeRTOS, Zephyr) -Motor control: BLDC, stepper, DC motors, PID, FOC -IoT connectivity: WiFi, BLE, LoRa, NB-IoT, MQTT, HTTP, TLS -Edge AI & TinyML (TensorFlow Lite for Microcontrollers, Edge Impulse) -Secure firmware: OTA updates, bootloaders, encryption, TLS -Cloud integration (AWS IoT, Azure IoT Hub, Google Cloud IoT) -Sensor interfacing (I2C, SPI, UART, ADC, PWM) -Power optimization and battery-powered system design -PCB bring-up, debugging with JTAG/SWD, logic analyzers, oscilloscopes I bring clean, modular code, deep hardware understanding, and a commitment to delivering results that work reliably in the real world. Let’s connect and make your embedded project a success.
