I am involved in high-stakes projects related to application DBA, Application Maintenance in Operational Condition (MCO), SQL performance, application migration, batch processing, production support, and the reliability of critical environments.

My role is to bridge the gap between business, IT, development, production, and operations: defining needs, impact analysis, technical and functional diagnostics, writing specifications, optimizing processes, securing production deployments, and sustainable improvement of operations.

I bring significant value to complex Oracle environments: taking over existing systems, reducing processing times, ensuring data flow reliability, improving data quality, providing operational documentation, recovery procedures, and team support.

Strong skills: Oracle Database, PL/SQL, Pro*C, Oracle Forms, SQL Performance, RMAN, Shell/KSH/C Shell, Unix/Linux, batch processing, Autosys, Control-M, CFT, data migration, production support, and SQL optimization.

I am primarily looking for long-term or hybrid assignments in the Île-de-France region, focusing on Technical Leadership, Application DBA, MCO, SQL Performance, application migration, and securing critical data and application platforms.
