About Adrien

AI LLM and Fullstack Developer (Vue, Angular, Node)
Also a C++17 engineer

My most interesting side-project: github.com/dridri/bcflight
Fully custom-coded drone and UAV flight controller for RaspberryPi with custom-designed electronic circuits.


Self-taught, I became interested in computing at the age of 6 and have developed my skills over the years in various fields ranging from system administration to web & mobile development and embedded systems.

In recent months, my expertise has shifted towards LLMs and their use in a B2B context, addressing various RAG, fine-tuning, and scoring challenges.


I had the opportunity to work for one year on the staff of the 42 school just after completing my initial training there, and then I moved on to freelance missions.

During the COVID period, I attempted to co-create an online appointment booking and business management solution (initially aimed at the beauty sector). Unfortunately, our product could not find its place in a market disrupted by COVID.
