About Lucas

Engineer specialized in embedded software development, I support individuals, start-ups, SMEs, and industrial companies as a freelancer in bringing their ideas to life, from expressing the need to bringing the solution to market.

I work on targeted missions (business software, embedded systems, IoT) or global projects, in collaboration with my associate, an electronics expert. Together, we provide comprehensive knowledge to cover all stages of the product lifecycle: R&D, prototyping, industrialization, CE marking, and small to medium series production. We transform your ideas into patented, industrialized, and commercialized products, while integrating industrial constraints from the design phase.

Our collaboration allows us to combine our skills for more advanced solutions and faster development. Thanks to our Protelec structure, we have an extensive network of suppliers (France and Asia) and various equipment (electronic hardware, 3D printing, tooling, etc.), which allows us to accelerate the completion of your project.

Looking forward to discussing your future projects with you!

For electronic missions, you can contact my associate:
