Useful AI, built with care.
I’m a Machine Learning & AI Consultant at Sopra Steria, working on computer vision, LLMs, and the software needed to put them into practice. Piano is the other half of how I think.
Software by day. Piano after hours.

How I work
How music shapes my work.
Software and music both ask for attention, structure, patience, and plenty of revision. Piano has shaped the way I approach technical work.
Understand
Start by understanding the people, the problem, and the data.
Build
Turn the moving parts into a system that is clear and maintainable.
Improve
Test it, listen to feedback, and keep improving the parts that matter.
Selected experience
From software to AI.
I started in full-stack development and gradually moved into data science and AI. That engineering background still shapes how I work today.

Beyond the screen
What piano teaches me.
I’ve played classical piano for more than fifteen years. It teaches me patience, focus, and how much difference a small detail can make.
Piano is where I slow down, practise, and listen.
