About Sacha

Hardware engineermechanical and robotics– Specialized in the design and prototyping of innovative products

Do you have a project requiring fine integration between mechanics, electronics, and embedded software?
I intervene from the idea or your technical advances to progress in technological and usage validations, certification, and production. Until reaching an industrialized and marketable product.


For 10 years, I have participated in more than 30 innovative and/or industrial projects: urban wind turbines, 3D printers, robots, electric vehicles, mini-purification stations, automated distributors…
Some have seen me intervene as lead designer, others in prototyping and optimization of existing concepts.

My added value:

CAD mastery (6000 hours of experience) in mechanical design, electronic integration, and monitoring of embedded software development

Solid network of suppliers, subcontractors, and technical partners

Concrete experience in industrialization and patent filing

Ability to prototype quickly internally thanks to a complete workshop (machines, tools, stocks)

Proven methodology to evolve a project from prototype to series with controlled risk

What I can deliver:

Mechanical design and detailed CAD


Functional prototypes (machining, assembly, testing)

Product optimization for industrialization

Technical monitoring and manufacturing coordination

I work with startups, SMEs, and manufacturers looking for a partner capable of transforming a concept into a product ready to be manufactured.

Whether as reinforcement for your teams or autonomously, on an ambitious project or one that can be produced directly, do not hesitate to contact me to discuss it.
