Damian O.

I am a UK-based Electronics Engineer with over 25 years of professional experience in electronic product development, schematic design, PCB layout, embedded systems, prototyping, and manufacturing. I specialise in taking products from an initial idea or existing prototype through to a fully functional, production-ready design. My focus is not simply on making a circuit work, but on developing practical, reliable and cost-effective products that can be manufactured efficiently. I have developed many products using the ESP32 family, including ESP32-S3, as well as a wide range of other microcontrollers and embedded platforms. Experience includes: ESP32 / ESP32-S3 • STM32 • ARM • AVR/Atmel • PIC • Nordic and other MCU platforms I can provide firmware development in C/C++ and other languages where required, including: - Hardware drivers - Sensor interfaces - I2C, SPI, UART, CAN and other communication buses - Wi-Fi and Bluetooth/BLE - RF and wireless systems - Displays and user interfaces - Motor and actuator control - Power-management and battery-operated products - Bootloaders and firmware updates - OTA updates - Hardware programming and debugging - Production programming and testing I can support the complete development cycle: Concept → Architecture → Schematic → PCB → Firmware → Prototype → Testing → Design Optimisation → Production Through my UK-based company, I can provide more than design files. I can arrange: - PCB manufacture - Component sourcing - PCB assembly - Firmware programming - Prototype assembly - Functional testing - Fully assembled and tested prototypes - Small and medium production batches Depending on the project, I can provide a complete engineering package including: - Editable Altium schematic and PCB source files - Gerber/ODB++ manufacturing files - Pick-and-place files - Complete BOM with manufacturer part numbers - Assembly drawings - Firmware source code - Compiled production firmware - Programming instructions - Test procedures - Prototype documentation - Manufacturing documentation
