About Thomas

My expertise lies in instrumentation. I am particularly skilled in electronic design, mechanical design, and software development. I worked at the Paris Observatory on satellite design projects and their test benches, then in the industrial sector for product development in the photonics field.
My experience has allowed me to work on a wide range of equipment and deliver numerous instruments and industrial products that meet demanding safety and reliability standards.

Services offered:
◦ R&D and prototyping;
◦ Electronic design, custom printed circuit boards, component assembly, and wiring;
◦ Mechanical design (3D models, subtractive manufacturing, sheet metal enclosures, surface treatments, aluminum profile assemblies, motorization, and automation);
◦ Embedded software design, graphical interface design, signal processing;
◦ Optimization and creation of documentation for product industrialization (BOM, assembly procedure, user manual);
◦ Advice and support for carrying out conformity tests for CE marking (electromagnetic compatibility and electrical safety);
◦ Series production.

I have a vehicle and am available. Do not hesitate to contact me to discuss your projects.
