LUCAS FRERY

ELECTRONICS HARDWARE ENGINEER

PCB | EMBEDDED SYSTEMS | SYSTEM INTEGRATION

I develop electronic systems from initial requirements through electrical architecture, component selection, schematic and PCB design, prototype and bring-up, system integration, and validation.

About

Hardware engineering with a practical lab mindset.

I am an electronics hardware engineer specialising in PCB design, embedded systems, and system integration for UAVs, robotics, and autonomous defence platforms.

My work takes products from early requirements to validated hardware: electrical architecture, component selection, schematic design, PCB layout, prototyping, board bring-up, and measurement-led debugging. I combine practical lab work with systems thinking to turn technical requirements into reliable electronics.

I am particularly drawn to applications where hardware must be robust, measurable, and practical. My focus is on developing electronics that are not merely functional on paper, but well understood, thoroughly validated, and ready to integrate into complete systems.
