Aqib N.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 Nov 5, 2026.

I help hardware startups and product teams build production-ready embedded systems across firmware, embedded Linux, IOT and edge AI. I am passionate Embedded Engineer with strongest work in turning prototypes into stable, testable, production-ready systems: MCU firmware, hardware bring-up, connectivity, embedded Linux gateways, MQTT/AWS IoT telemetry, camera pipelines, and edge-AI inference. EMBEDDED FIRMWARE • ESP32 / ESP-IDF firmware for Wi-Fi, BLE, sensors, MQTT, OTA, and cloud-connected devices • STM32 firmware with FreeRTOS, drivers, UART/SPI/I2C/CAN, bootloaders, and hardware bring-up • Nordic nRF52840 / nRF9160 / nRF5340 firmware using Zephyr RTOS, BLE GATT, low-power design, and FOTA • Sensor integration, power optimization, debugging, testing, documentation, and source-code handover • Services include ESP32 / ESP-IDF firmware, STM32 firmware, Nordic nRF52/nRF9160, Zephyr RTOS, FreeRTOS, BLE GATT, Wi-Fi, LTE-M, NB-IoT, LoRa, UART/SPI/I2C/CAN, bootloaders, OTA/FOTA, low-power firmware, sensor integration, and hardware bring-up. EMBEDDED LINUX • Yocto / Buildroot Linux images, BSP customization, device tree, kernel configuration, and system services • Raspberry Pi CM4, i.MX6/i.MX8, Linux gateways, modem/networking, MQTT bridges, and production device setup • Linux driver-level debugging, boot issues, hardware interfaces, camera pipelines, and field reliability improvements • Services include Embedded Linux, Yocto, Buildroot, BSP customization, device tree, kernel configuration, Linux device drivers, Raspberry Pi CM4, i.MX6/i.MX8, system services, modem/networking, MQTT gateways, and production device setup. EDGE AI / CAMERA SYSTEMS • OpenCV, YOLO, OCR/ALPR, RTSP streams, object detection, visual inspection, and safety scoring systems • Embedded Linux camera pipelines, edge inference, model integration, performance optimization, and cloud-connected AI workflows • Services include Edge AI, computer vision, OpenCV, YOLO, RTSP camera streams, OCR/ALPR, visual inspection, object detection, driver safety scoring, crack/pothole detection, embedded inference, Jetson, Raspberry Pi, and Coral TPU. BEST-FIT PROJECTS • ESP32 / STM32 / Nordic nRF firmware • BLE wearable and low-power sensor devices • Zephyr RTOS / FreeRTOS systems • IoT devices with MQTT, AWS IoT, OTA, and telemetry • Embedded Linux gateways and Yocto/Buildroot systems • Camera-based edge-AI and computer vision systems If you need someone who can own the embedded system layer — not just patch code — I can help turn your prototype into a reliable product.
