I will design professional schematic and pcb

I am an Electrical Engineer specializing in Embedded Systems, PCB Development, IoT, and Microcontroller-based product development. I work on complete hardware solutions, from component selection and schematic creation to firmware development, PCB layout, debugging, and prototype testing.

My expertise includes:

• ESP32, ESP32-S3, ESP32-C3, ESP8266, and Arduino
• STM32 microcontrollers including STM32F1, F4, G4, and H7 families
• ATmega and AVR microcontrollers
• Custom PCB development and schematic creation
• Ethernet, W5500, LAN PHY, and PoE-based hardware
• Wi-Fi, Bluetooth, BLE, MQTT, ESP-NOW, and IoT communication
• USB Type-C, USB OTG, UART, SPI, I2C, CAN, and RS485 interfaces
• Sensors, ADCs, DACs, relays, MOSFETs, displays, and control circuitry
• Power supply development using LDOs, buck, boost, buck-boost, battery, and USB-powered architectures
• Complete electronic circuit development
• PCB layout and component selection
• IoT and wireless system integration
• Ethernet and PoE hardware implementation

I focus on practical, manufacturable, and easy-to-understand hardware solutions. Schematics, connections, and system architecture are clearly documented so the project can be assembled, tested, and mai
