About Mohamed

I am a senior Oracle Database Administrator with over 20 years of experience in the administration, optimization, migration of complex environments, and PL/SQL development for companies such as BNP Paribas Cardif, BPCE, and Atos.

Passionate about system performance and reliability, I have managed Oracle databases (9i → 19C), carried out numerous PL/SQL developments (optimized packages, triggers, stored procedures), and also worked on PostgreSQL and MongoDB.

Recognized for my pragmatic approach, rigor, and ability to bridge the gap between technical and business teams, I am currently seeking new opportunities to leverage my expertise for performance, data quality, and advanced PL/SQL development.
