Hi, I'm Muzammil — Turning Electronic Ideas into Reliable, Production-Ready Systems With years of hands-on experience in PCB design and embedded development, I specialize in creating efficient, compact, and cost-effective solutions for IoT, automation, and consumer electronics. I’ve successfully delivered everything from simple sensor modules to complex, multi-layer PCB systems with integrated firmware, always focusing on quality, performance, and long-term reliability. 1. What I Offer: Complete Embedded Systems & PCB Design Services -Custom PCB Design & Development: Expertise in schematic design, manual PCB routing, and component placement using tools like EasyEDA, Altium, KiCad,Cadance and Proteus. Capable of designing single-layer, double-layer, and multi-layer PCBs optimized for space, thermal, and electrical performance. -Firmware Development & Microcontroller Programming: Skilled in C/C++ for developing firmware on microcontrollers such as ATTiny, ESP32, STM32, and AVR. Includes integration with sensors, displays, actuators, Neopixels, and real-time control using timers, interrupts, and power modes. -IoT System Integration & Wireless Communication: Development of Wi-Fi, Bluetooth, GSM, and LoRa-based solutions using MQTT, Blynk, and custom cloud platforms. Ideal for smart home devices, wireless monitoring, remote control systems, and low-power connected applications. 2. Tools, Platforms & Prototyping Skills -Design Tools: EasyEDA, Altium Designer, KiCad, Proteus -Firmware & Languages: C, C++, Arduino IDE, PlatformIO,Espressif -Prototyping & Testing: BOM creation, Gerber file preparation, breadboard testing, soldering, and hardware debugging -Simulation: Circuit simulation for pre-production logic and waveform validation -Interface Development: Basic HMI and control feedback using OLED/TFT displays, capacitive touch sensors, and haptic actuators 3. Why Work with Me? -End-to-End Development: I deliver complete embedded systems, from concept to production-ready design. -Reliable Circuit Design: My manual routing and structured component placement help ensure signal integrity, noise immunity, and thermal efficiency. -Efficient and Detail-Oriented: My work is grounded in precision, clear documentation, and readiness for manufacturing and scaling.
