Ever Q.

I’m an electronics engineer with 15+ years of experience in hardware development, PCB design, and embedded electronics. I help companies turn electronic concepts, schematics, and prototypes into reliable, manufacturable hardware. My specialty is PCB design with KiCad and Altium Designer, combined with hands-on experience developing embedded electronics, sensor interfaces, and industrial monitoring systems. What I can do for you PCB Design: Schematic capture, multilayer PCB layout, mixed-signal design, custom symbols and footprints, and high-density boards. Embedded Hardware: ESP32-based systems, microcontrollers, sensor interfaces, data acquisition, and peripheral integration. Analog Electronics: Analog front-ends, operational amplifier circuits, filters, signal conditioning, and power management. Industrial IoT & Instrumentation: Sensor-based monitoring systems, gas detection, industrial communications, and remote data acquisition. Connectivity & Interfaces: SPI, I²C, UART, USB, Wi-Fi, Bluetooth, RS-485, and Modbus. Design for Manufacturing (DFM): Component selection, BOM preparation, footprint verification, Gerber generation, and assembly-ready deliverables. Hardware Debugging: Troubleshooting existing designs, identifying circuit issues, and improving boards that don't perform as expected. Real-world hardware experience I have developed and integrated electronics for industrial monitoring applications, including: SO₂ monitoring for fumigation in fruit storage containers. NH₃ monitoring for industrial food-processing environments. Embedded sensor systems, custom electronics, and data acquisition hardware. My design approach I design with manufacturability, electrical reliability, and practical debugging in mind from the beginning. I have my own electronics lab, including an oscilloscope and bench power supplies for prototype bring-up, troubleshooting, and hardware verification. You will receive organized project files, clear documentation, and manufacturing deliverables tailored to your project. I can work from an existing schematic, improve an unfinished PCB, troubleshoot a failing design, or develop hardware from initial requirements. Tools: KiCad, Altium Designer, C/C++, Python, LTspice. If you need a PCB designer who understands both the circuit and the product it belongs to, send me your schematic, project requirements, or existing PCB files. I'll review the problem and give you an honest assessment of the work involved.
