About Sylvain

Thanks to generative AI, I can develop any type of web or mobile application, from a simple prototype to a finished application, and at a much lower cost than I would have offered a few years ago. And I also have 15 years of experience in development without AI.

A short, non-exhaustive list of what I can develop (or implement):
- a web application
- an Android or iOS mobile application, or both
- an automation application
- a rewrite of an existing application (any technology)
- an AI-based application (image recognition, video analysis, Text To Speech, Speech To Text, etc.)
- local AI (ongoing self-training)
- fine-tuning (ongoing self-training)

I am very keen on innovation, so please feel free to contact me to discuss your project. I will give you my opinion (if you ask me!) and answer your questions (if you have any), to the best of my ability.
