Freelancer profile translated to English.

Description

Being an expert in mobile app development, websites, complex backends, SQL, and AI automation for over 15 years is great, and that's me (except for AI, of course - although I have a Master's degree in AI!).

Knowing how to communicate with your client to formalize, guide, simplify, and organize needs is even better.

And that's where I differentiate myself the most from my peers.

I know what's possible within a given time and budget, and I don't want to lie like many web, mobile, or AI agencies do.

What I like:

- Projects with connected objects

- Projects with maps

- Projects with antennas

- Projects with music

- Projects with airplanes

- But also horses, motorcycles, agriculture, cities, travel...

Whether you're starting from scratch or I have to untangle the spaghetti mess left by your previous agency, I handle it perfectly.

I am also an occasional trainer, for example in C# Maui AI Coding or Web/API Security.

I can also do R&D on more complex topics, such as computer vision or LoRaWAN integration.

Feel free to contact me, I don't bite ;)
