About
I specialize in embedded systems, electronics, and PCB design, helping turn ideas and prototypes into functional hardware.
I can work across both hardware and firmware, including schematic design, PCB layout, microcontroller programming, debugging, prototyping, and manufacturing files.
My technical skills include:
• ESP32, STM32 and Arduino development
• C/C++ and Python programming
• KiCad, Altium Designer and EasyEDA
• Schematic capture and circuit design
• 2-layer and 4-layer PCB design
• Component selection and BOM creation
• Gerber, BOM and Pick-and-Place/CPL preparation
• PCB debugging and troubleshooting
• SMD soldering and prototyping
• Sensors, displays and communication interfaces
• UART, I²C, SPI, USB, RS-232 and RS-485
• 3D printing and prototype development
I am comfortable working from an existing prototype or developing a solution from requirements. I focus on practical, manufacturable designs and clear communication throughout the project.
I am a native Portuguese speaker from Portugal and can communicate in English.
