Mohsin A.
Robotics & PCB Engineer | Sensor Designing | Control Systems
I’m an experienced and passionate electronics engineer with 4+ years of practical expertise in hardware development, PCB design, circuit simulation, microcontroller programming, and robotics. I work on everything from basic electronics prototyping to complex, multilayer PCB and firmware design for commercial, academic, and industrial applications. My strength lies in designing end-to-end systems that combine intelligent firmware with robust and optimized hardware. Whether you need a simple circuit designed or a complete robotic solution built from scratch, I bring a comprehensive skill set that ensures performance, reliability, and scalability. What I Can Do for You 1) Custom PCB Design & Layout I design single- and multi-layer PCBs using EasyEDA, Altium Designer, and Proteus. Each layout is optimized for performance, manufacturability, and clean routing. I ensure proper DRCs, ground planes, and signal integrity — producing ready-to-order Gerber files with BOM and schematic documentation. 2) Circuit Design & Simulation Using NI Multisim, Proteus, and LTspice, I simulate analog/digital circuits to validate concepts before hardware testing. This helps minimize costly prototyping errors and ensures reliable, functional designs. 3) Microcontroller-Based Systems Development I develop firmware for controllers like Arduino, ESP32, and STM32 using Arduino IDE, PlatformIO, and STM32CubeIDE. My applications include sensor integration, real-time control, motor driving, and wireless communication — written in modular, optimized C/C++ code with complete documentation. 4) Robotics & Autonomous Systems I design intelligent robots for real-world use, education, and competition. One of my flagship builds is REAPER: 🚨 Reconnaissance Engaged Autonomous Patrol and Engaging Robot – A rugged 4WD robot equipped with real-time video surveillance, AI-based human detection, and autonomous patrol functions. REAPER integrates wireless control, onboard vision, and advanced control logic, designed for security, monitoring, and tactical applications. Other robotics projects include: i) Robotic Arms Controlled via EMG Signals – Interpreting muscle activity to control servo motion ii) Wireless ESP32 Rovers with Camera Modules – Live video, autonomous pathing, and remote control iii) Competition Bots – Line followers, edge detectors, balloon busters, and obstacle avoiders iv) Custom Controller Boards – Built-in L298N drivers, servo support, power regulation, and modular design 5) IoT Systems & Wireless Communication I build connected systems using ESP32/ESP8266 for smart automation, data logging, and wireless control. My solutions support WiFi/BLE, MQTT/HTTP APIs, OTA updates, and mobile-friendly interfaces. 6) Debugging, Optimization, and Documentation Need help fixing or enhancing your electronics project? I troubleshoot circuits, refine firmware, and optimize for power, thermal, and signal efficiency. Every project is delivered with clear documentation: schematics, BOMs, PCB files, and code comments. Tools, Platforms & Skills 1) PCB Tools: EasyEDA, Altium Designer, Proteus, NI Multisim, LTspice 2) Microcontrollers: Arduino (Uno, Nano, Mega), ESP32, ESP8266, STM32 3) Languages: C, C++, MicroPython 4) Frameworks/IDEs: Arduino IDE, PlatformIO, STM32CubeIDE, FreeRTOS (basic) 5) Protocols: I2C, SPI, UART, PWM, WiFi, BLE 6) CAD: AutoCAD (for enclosures, layouts), Fusion 360 (basic) 7) Expertise: Real-time debugging, signal filtering, sensor calibration, motor control What Sets Me Apart 1) End-to-end system design: concept to circuit to firmware 2) Battle-tested builds: used in competitions, research, and demos 3) Maintainable code and schematic structure 4) Quick response and support for project scaling 5) Prototyping to production-ready solutions Project Types I Work On 1) Smart robotic platforms and mobile surveillance bots 2) EMG-based assistive robotics and gesture-controlled systems 3) IoT automation, data loggers, and remote monitoring 4) Custom PCB design and microcontroller programming 5) Educational kits for STEM electronics and robotics 6) Motor driver boards and intelligent actuators 6) Wireless telemetry and real-time sensor platforms Let’s collaborate to turn your idea into a functional, reliable, and efficient reality — whether it’s a smart device, a robotic system, a custom board, or an embedded product with full firmware-hardware integration.
