Arslan k.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 develop production-ready embedded systems, custom PCBs, and firmware using STM32, ESP32, C/C++, FreeRTOS, CAN, BLE/Wi-Fi, and embedded Linux — from initial prototype to tested hardware ready for production. I work across both hardware and firmware, so I can handle the complete embedded product instead of treating the PCB and software as separate problems. Core expertise: Embedded Firmware: C/C++, STM32, ESP32, ARM Cortex-M, FreeRTOS, bare-metal firmware, device drivers, bootloaders, interrupts, timers, ADC and PWM PCB & Hardware Design:Schematic design, component selection, multilayer PCB layout, board bring-up, debugging, BOM, Gerber/CPL files and DFM using Altium Designer and KiCad Communication Protocols:CAN / CANopen, UART, SPI, I2C, RS485, Modbus, Ethernet, USB, MQTT and TCP/IP IoT & Wireless:Wi-Fi, BLE, LoRa, MQTT, wireless sensors and low-power battery-operated devices Motor & Control Systems: DC, BLDC, servo and stepper motors, encoders, PID control, motor drivers and real-time control systems Embedded Linux & Robotics: Raspberry Pi, NVIDIA Jetson, ROS/ROS2, sensors, computer vision, OpenCV and system integration I have worked on 25+ embedded and electronics projects, including industrial automation, autonomous systems, IoT products, motor-control systems, custom sensor electronics and embedded computer-vision applications. Some of my work includes: Industrial Automation & CAN Systems STM32-based control systems, CAN/CANopen communication, motor controllers, sensors and integration with industrial equipment. Custom Embedded Hardware Designed and developed MCU-based control boards, power electronics, sensor interfaces, communication electronics and production PCB designs. Low-Power IoT Devices ESP32-based connected products using Wi-Fi/BLE, sensor integration, power optimization and custom firmware. Robotics & Autonomous Systems Worked with ROS/ROS2, SLAM, sensor fusion, motor control, embedded Linux and computer vision for autonomous robotic systems. Edge AI & Computer Vision Deployed YOLO/OpenCV-based real-time vision systems on embedded platforms including Raspberry Pi and NVIDIA Jetson. Development stack: STM32 | ESP32 | Embedded C | C++ | Python | FreeRTOS | CAN | CANopen | UART | SPI | I2C | RS485 | Modbus | BLE | Wi-Fi | MQTT | Altium Designer | KiCad | Raspberry Pi | NVIDIA Jetson | ROS/ROS2 I can support your project through the complete development cycle: Requirements → Architecture → Schematic → PCB → Firmware → Bring-Up → Debugging → Testing → Production You receive clean source code, organized hardware files, manufacturing-ready PCB documentation, clear communication and engineering decisions made with reliability and production in mind. If you're developing an embedded product, STM32/ESP32 device, custom PCB, IoT system, motor controller, industrial controller or robotic system. send me the project details and I can help you determine the best development approach.
