Project details
Do you need an expert view on your electronic design before taking it to the next step (PCB layout, production....)?
If you need a second pair of eyes, I can issue a full review of your schematics and provide a detailed report.
I'll pinpoint any potential problem I detect, possible parts alternatives, and check the design against your specifications. I'll also suggest modifications to improve specific points such as power consumption, noise, stability, robustness, or lower BOM costs.
The 3 options are as follows:
- 1: Hobbyist/personal projects only. Any project you are working on in a non-professional setting and not meant for mass production.
- 2: Projects in a professional setting. The review will take production concerns, reliability and costs into account.
- 3: as 2 but for projects with additional safety concerns, such as products that must comply with safety-related standards, in particular medical devices.
Please contact me before placing an order so that we can make sure your particular project is a good fit for this service. If you need an NDA signed, you can send it to me via message and I'll send it back signed.

Redesign LED Clock PCB (KiCad-Based)
Working with Guillaume on our clock electronics development was a genuinely great experience. He operates with a level of autonomy that is hard to find — give him a challenge, and he will find the solution. Every technical hurdle we encountered during the project, Guillaume resolved independently, bringing creativity and solid engineering know-how to each problem.
His deep understanding of electronics, combined with his self-sufficient work style, meant the project moved forward smoothly even when the problems were complex. If you need someone who can take full ownership of electronics development and deliver results, Guillaume is your person — we wouldn't hesitate to work with him again.
