I am a PCB Designer and Embedded Systems Engineer specializing in developing reliable, production-ready hardware solutions. I have hands-on experience in schematic design, multi-layer PCB layout, and firmware development for microcontrollers such as STM32, ESP32, and Arduino. I have worked on various projects including IoT devices, sensor-based systems, and custom embedded solutions. My workflow covers the full development cycle—from concept and circuit design to PCB fabrication files (Gerber, BOM) and firmware programming. I focus on creating efficient, cost-effective, and manufacturable designs while ensuring performance and stability. I am also experienced in debugging, testing, and optimizing both hardware and firmware to meet real-world requirements. I use industry-standard tools such as Altium Designer, KiCad, and Eagle, and I am comfortable working with communication protocols like UART, SPI, and I2C. I am committed to delivering high-quality work, clear communication, and on-time project completion.
