With over 12 years of experience as a Tech Lead and back-end developer, I have led complex IT projects and supported companies like Sncf connect, Decathlon Societe Generale, Bnpparibas, and HAS in their digital transformations.

Strengths:
Development Expert : I design innovative technical solutions, ensuring performance and quality.
Team Management : I support teams to help them grow technically.
Technical Collaboration : I work with architects to integrate solutions into existing systems.

I am also passionate about artificial intelligence and machine learning, fields I actively follow.

My goal is to create solutions that not only meet technical needs but also enable the capture of new business opportunities.
